If you searched for a tumbled crystal numbers set, these five options are better understood as assorted polished-stone collections rather than numbered sets: none is described as including numbered crystals. I would start with National Geographic for an educational collection with an identification sheet, Fantasia for broad variety, or DANCING BEAR if larger individual stones and a booklet matter more than a fixed assortment. The central tradeoff is clear: bulk collections offer more stones or varieties, but their contents can vary, while smaller assortments may be easier to sort or use in projects. I rank these options by how well their stated contents, supporting materials, and typical stone sizes serve different buyers—not by a promise of numbered pieces.

More Details on Our Top Picks
National Geographic Polished Stones and Crystals, 2 lb Collection
I put the National Geographic collection first because it balances a substantial two-pound quantity with the clearest learning support in this lineup. Its polished assortment names familiar types such as agate, amethyst, quartz, tiger’s eye, sodalite, hematite, and jasper, and the included identification sheet and learning guide give a beginner somewhere to start when sorting the stones. That makes it more useful for a family activity or basic geology display than a bag that arrives with stones but no reference material.
The main tradeoff is scale: pieces are approximately half an inch, smaller than DANCING BEAR’s typical one- to 1.25-inch stones. Small pieces can work well when a buyer wants many samples for a sorting activity, craft, or decorative arrangement, but they are less suited to handling one stone at a time or making a statement display. Stone varieties may vary, too, so I would not treat the named list as a guaranteed inventory. Compared with Fantasia’s typical breadth of at least 15 types, this collection’s advantage is its guide—not a stated higher variety count. It is my best all-round choice when the stones need to teach as well as decorate.
Pros:- Two-pound collection offers a substantial quantity.
- Identification sheet and learning guide support basic stone sorting.
- Named examples include quartz, agate, amethyst, tiger’s eye, and jasper.
- Can serve learning, craft, and decorative projects.
Cons:- Stones are approximately half an inch, smaller than DANCING BEAR’s typical pieces.
- Stone types and varieties may vary, so the exact mix is not fixed.
- No numbered-stone format is specified.
Best for: Families, beginner collectors, and educators who want a substantial assortment with a basic identification reference.
Not ideal for: Buyers who need larger individual stones, a fixed list of exact varieties, or numbered pieces.
- Brand:Blue Marble
- Collection:National Geographic Premium Polished Stones
- Weight:2 lb
- Typical stone size:Approximately 1/2 inch
- Named stone types:Agate, amethyst, blue quartz, rose quartz, tiger’s eye, sodalite, hematite, assorted jasper
- Included materials:Identification sheet and learning guide
- Recommended age:8 years and up
- Model:NG12PROCK2LB
Our verdict“I rank this first for its useful learning materials and generous assortment, provided small, variable stones suit the project.”
Fantasia Premium Brazilian Tumbled Natural Stones, Assorted Mix, Small, 0.75–1 in, 2 lb
For buyers who care most about seeing many different stone types in one collection, Fantasia’s two-pound mix has the strongest stated variety claim here: it typically includes at least 15 types. Its stones are described as tumbled, polished, and hand graded, giving the assortment a more curated angle than a listing that only promises random rounded stones. Against National Geographic, Fantasia emphasizes material variety rather than an identification sheet or learning guide.
That breadth comes with uncertainty. The selection can differ from the pictured mix, and natural imperfections or minor chips may appear, so I would not choose it for a perfectly uniform display or a project requiring a known stone inventory. The listed size is 0.75 to 1 inch, smaller than DANCING BEAR’s typical range but larger than National Geographic’s approximate half-inch pieces. It sits between those choices on handling size while offering a wider typical variety count than either product specifies. I see it as the best fit for a collector or craft user who values color and variety more than predictable contents.
Pros:- Typically includes at least 15 stone types.
- Two-pound quantity suits sorting and multi-piece projects.
- Stones are described as tumbled, polished, and hand graded.
- Listed size range is 0.75 to 1 inch.
Cons:- The mix varies and may differ from pictured stones.
- Natural imperfections or minor chips may occur.
- No identification guide or numbered pieces are specified.
Best for: Collectors and crafters who want a broad, colorful assortment and can accept variation and minor natural flaws.
Not ideal for: Buyers who need exact stone types, consistently flawless pieces, or a learning guide included in the package.
- Weight:2 lb
- Stone size:0.75–1 in
- Material:Assorted natural stones
- Finish:Tumbled and polished
- Typical variety:At least 15 stone types
- Package dimensions:6 × 6 × 2 in
- Manufacturer:Fantasia Mining, Inc.
- Number of pieces:1 package
Our verdict“I recommend Fantasia when variety is the priority and a changing mix matters less than an exact inventory.”
DANCING BEAR Tumbled Polished Gemstones, 2 lb with Rock and Mineral Booklet
DANCING BEAR is the stronger pick when a buyer wants stones that are easier to handle individually. The listed size is approximately 1 to 1.25 inches, making these pieces larger than both National Geographic’s half-inch stones and Fantasia’s 0.75- to 1-inch range. A 27-page illustrated rock and mineral booklet adds a useful reference, although it is a booklet rather than the identification sheet and learning guide supplied with National Geographic.
The two-pound amount matches those two alternatives, but its mix is random and can include duplicates, dyed stones, and changing colors. That makes it less dependable for someone planning a precise set of different specimens. Compared with Fantasia, it offers larger typical pieces and a named booklet, while Fantasia claims a typical minimum of 15 stone types. I would choose DANCING BEAR for a hands-on display or sorting activity where stone size is more important than a broad guaranteed selection. It is not a numbered set, and its varied contents do not provide a reliable route to a complete, labeled sequence.
Pros:- Typical stones are approximately 1 to 1.25 inches.
- Includes a 27-page illustrated identification booklet.
- Two-pound assortment includes a range of polished stone types.
- Larger pieces are easier to handle than National Geographic’s half-inch stones.
Cons:- Stone selection, colors, and sizes vary, and duplicates may occur.
- Materials may include both natural and dyed stones.
- No numbered pieces or fixed stone inventory are specified.
Best for: Families and beginner collectors who prefer larger pieces and want an illustrated rock and mineral booklet.
Not ideal for: Buyers who need a fixed mix, no duplicates, exclusively natural coloration, or numbered stones.
- Brand:DANCING BEAR
- Weight:2 lb
- Typical stone size:Approximately 1 to 1.25 inches
- Included booklet:27-page rock and mineral identification booklet
- Materials:Natural and dyed stones
- Age range:3 years and up
- Educational objective:STEM
- Assembly location:Eugene, Oregon, USA
Our verdict“I favor this set over smaller collections when easy handling and a booklet matter more than a predictable assortment.”
Rockcloud 1 lb Assorted Tumbled Polished Stones
Rockcloud’s one-pound assortment is the practical middle ground for buyers who want polished stones for several kinds of small projects without taking home a two-pound collection. Its approximate 0.7- to 1-inch pieces are larger than National Geographic’s listed stones, while the smaller total weight makes it a more limited supply than the three two-pound options. The rounded shape and smooth finish are a sensible match for crafts, jewelry making, or home decor.
Its weakness is predictability. Stone types are selected at random, and the details say size and color may vary; the product also describes artificial color enhancement. That makes it a less straightforward choice for a buyer seeking an all-natural, known mix than Fantasia, which specifically describes natural stones, or a buyer seeking learning materials like those included with National Geographic and DANCING BEAR. The supplied color specification is green, but the assortment is still described as variable. I would treat it as a general-purpose craft assortment, not a reliable numbered collection or a clearly documented specimen kit.
Pros:- One-pound quantity is lighter than the three two-pound options.
- Approximate 0.7- to 1-inch size suits many small craft uses.
- Rounded, polished stones have a smooth finish.
- Described for crafts, jewelry making, and home decor.
Cons:- Specific stone types are selected at random.
- Size and color may vary; artificial color enhancement is listed.
- No learning materials or numbered stones are specified.
Best for: Crafters who need a moderate quantity of smooth, rounded stones for mixed decorative or jewelry projects.
Not ideal for: Collectors who need a fixed list of stone types, an identification guide, or a clearly unenhanced natural assortment.
- Brand:Rockcloud
- Quantity:1 lb (about 460 g)
- Typical stone size:Approximately 0.7–1 inch
- Stone type:Assorted natural gemstones
- Stone cut:Rounded
- Listed color:Green
- Treatment:Artificial color enhanced
- Item weight:16 oz
Our verdict“I would choose Rockcloud for general craft use when a one-pound assortment is enough and exact stone identities are not required.”
Assorted Tumbled Gemstones and Crystals, 0.7 lb
This is the lightest collection in the lineup, at 0.7 lb, and its 8–10 kinds of polished oval stones offer variety without a two-pound bag. The description gives a little more shape and size information than a general random-stone listing: pieces are approximately 1.5 to 3 cm, with a polished finish. It also guarantees black tourmaline and an amethyst cluster, which gives buyers two named inclusions to expect.
Those guarantees have limits: the package also promises a permeable plaster piece, and the remaining assortment varies. Buyers should not assume that the pictured mix will arrive or that the package contains a fixed list of 8–10 specific gemstone types. Compared with Rockcloud, this option lists a smaller total weight and a clearer oval shape; compared with National Geographic, it lacks an identification sheet or learning guide. I rank it fifth because its guaranteed inclusions and variable assortment offer less predictability for buyers who want to sort or teach from a documented stone list. It makes sense when compact size and the named pieces matter more than a learning reference or exact matching inventory.
Pros:- Lightest listed collection at 0.7 lb.
- Contains 8–10 kinds of polished stones, though the mix varies.
- Black tourmaline and an amethyst cluster are guaranteed.
- Oval pieces are approximately 1.5 to 3 cm.
Cons:- Most of the assortment is not fixed and may not match the pictured mix.
- The listed guaranteed inclusions also include a permeable plaster piece.
- No identification guide or numbered stones are specified.
Best for: Buyers who want a lighter assortment with oval polished stones and guaranteed black tourmaline and an amethyst cluster.
Not ideal for: Anyone who needs a fixed variety list, a learning guide, a numbered sequence, or a consistent match to product photos.
- Weight:0.7 lb (300 g)
- Stone size:About 1.5–3 cm
- Finish:Polished
- Shape:Oval
- Assortment:8–10 kinds; varies by package
- Guaranteed pieces:Black tourmaline, a permeable plaster piece, and an amethyst cluster
Our verdict“I recommend this compact option only when its guaranteed named inclusions and lighter quantity matter more than a predictable full assortment.”
How We Picked
I compared these products as tumbled crystal assortments, not as numbered sets, because none of the supplied product details promises numbered stones. That distinction matters: someone who needs consecutive numbers, a particular count, or a labeling system should not assume an assorted gemstone collection will provide it. I gave more weight to clear information about weight, typical size, variety, and included learning materials than to broad claims about possible uses.
My ranking reflects the needs these products serve. National Geographic leads for its combination of a two-pound quantity and an identification sheet with a learning guide. Fantasia follows for its stated typical breadth of at least 15 stone types, though it does not offer the same named educational materials. DANCING BEAR earns a place for its larger stated stones and illustrated booklet. Rockcloud suits a lighter general-purpose assortment, while the 0.7-pound collection is the most compact but also has the narrowest guaranteed-content information.
I also accounted for variability and tradeoffs rather than treating every assortment as predictable. Several products say types or colors vary, and some may include duplicates or imperfections. I have not treated a possible stone as guaranteed unless the product details say so. The ranking is a practical guide to choosing among these specific descriptions; buyers seeking exact numbered pieces should verify that requirement separately before choosing any of them.

Factors to Consider When Choosing Tumbled Crystal Numbers Set
For a search framed around a tumbled crystal numbers set, the first question is whether an assorted stone collection is actually what you need. These products are described as mixed polished-stone assortments; none promises numbered pieces. I would choose by the intended task—learning, display, crafts, or a smaller selection—then check whether size and variable contents suit it.
Check whether you need actual numbered stones
None of the five descriptions says that its stones are individually numbered or arranged in a numbered sequence. If you need numbered objects for a classroom activity, matching exercise, game, or inventory, do not assume that a mixed gemstone bag will work. The included booklets and guides help with identification, but they do not turn the stones into a numbered set. I would confirm the labeling format directly before buying for a task that depends on numbers.
Match piece size to how the stones will be handled
Size changes the way an assortment works. DANCING BEAR lists stones around 1 to 1.25 inches, the largest stated typical range here, while National Geographic lists pieces at about half an inch. Fantasia sits between them at 0.75 to 1 inch, and Rockcloud lists approximately 0.7 to 1 inch. The compact 0.7-pound assortment gives a 1.5- to 3-centimeter range. Larger stones can be easier to hold and display individually; smaller ones may be easier to group in a tray or use in small crafts. Check dimensions against the intended use rather than relying on a product photo.
Choose between variety and a known inventory
Mixed assortments trade predictability for variety. Fantasia states that its mix typically includes at least 15 stone types, while National Geographic names examples but says varieties may vary. DANCING BEAR also lists possible types, with duplicates possible. Rockcloud selects types at random, and the 0.7-pound package varies despite guaranteeing a few inclusions. These details are useful clues, not a promise that every package contains the same inventory. If a project needs specific stones, look for a fixed list and verify it before ordering.
Decide whether learning materials matter
Two options include references that make sorting more approachable. National Geographic supplies an identification sheet and learning guide; DANCING BEAR includes a 27-page illustrated rock and mineral booklet. I would favor National Geographic for a simple starting point alongside a varied assortment, and DANCING BEAR when larger individual pieces are a priority. Fantasia, Rockcloud, and the compact assortment do not list comparable guides in the supplied details, so buyers may need a separate reference if stone identification is part of the activity.
Read material and finish details with care
A polished finish describes how the stones are presented, not a guarantee of identical surfaces or color. Fantasia describes natural stones and notes that imperfections or minor chips may occur. DANCING BEAR says its mix can include natural and dyed stones, while Rockcloud lists artificial color enhancement. If natural coloration or a uniform appearance matters to your project, pay close attention to those disclosures. These are assorted products, so finish and appearance can differ from the product image or from one piece to another.
Use total weight as a quantity guide, not a piece count
The three larger collections—National Geographic, Fantasia, and DANCING BEAR—are each listed at two pounds. Rockcloud is one pound, and the compact assortment is 0.7 pound. Weight can help compare how much material is supplied, but it does not tell you how many stones will arrive: larger stones account for more weight per piece, and sizes vary. For a group activity or project requiring a specific count, verify piece quantity rather than estimating from package weight.
Frequently Asked Questions
Are any of these products a numbered tumbled crystal set?
No supplied description identifies individually numbered stones or a numbered sequence. These are mixed polished-stone assortments. National Geographic and DANCING BEAR include learning references, but those materials are not described as numbering each stone. If numbers are necessary for your project, verify the format with the seller before choosing one of these options.
Which option is best for learning to identify stones?
I would start with the National Geographic collection because it includes both an identification sheet and a learning guide alongside a two-pound assortment. DANCING BEAR is another useful choice, particularly if larger stones appeal to you, and it comes with a 27-page illustrated booklet. In either case, the actual mix may vary, so the guide does not guarantee that every named example will appear in the package.
Which assortment has the largest stated stones?
DANCING BEAR lists stones at approximately 1 to 1.25 inches, the largest typical range among these products. Fantasia lists 0.75 to 1 inch, Rockcloud approximately 0.7 to 1 inch, and National Geographic about half an inch. The compact assortment uses a centimeter range of approximately 1.5 to 3 cm. Because these are assortments, individual sizes can still vary.
Which product is the strongest choice for stone variety?
Fantasia makes the clearest variety claim, stating that its two-pound assortment typically includes at least 15 stone types. That is a typical mix, not a fixed inventory, and the selection may differ from the pictured stones. The compact assortment says it contains 8–10 kinds, while National Geographic and DANCING BEAR list examples but do not give the same stated minimum variety count.
Can I use these assortments for crafts or decoration?
The product details describe several options for craft or decorative use. National Geographic lists crafts and arrangements, while Rockcloud is described for crafts, jewelry making, and home decor. The right choice depends on the needed quantity and size; Rockcloud supplies one pound, while three alternatives offer two pounds. Check each product’s variation notes and material details if matching colors or a uniform appearance matters.
Conclusion
I would choose National Geographic for a beginner-friendly collection with an identification sheet and learning guide, and Fantasia if a broad, typically varied mix matters more than fixed contents. For larger individual stones and an illustrated booklet, DANCING BEAR is the clearest match. Rockcloud makes more sense for a moderate craft supply, while the 0.7-pound assortment suits someone who wants a lighter package with a few guaranteed inclusions. None of these is specified as a numbered set, so buyers who require numbered crystals should confirm that feature rather than relying on an assorted tumbled-stone collection.
