Crystal chips are one of the most versatile crystal materials. They’re used for resin art, candle tops, planter decoration, aquariums, jewelry making, gift bottles, and many other applications. But before anyone orders, the same three questions always come up:
- How big is a chip, actually?
- How many do I get for 100 g?
- What shape should I expect?
using real photos from our own stock — no stock images, no guessing.
1. How big is a crystal chip?
Chips are sold by size range, not exact measurement, so no two pieces in a batch are exactly alike. Here is the full range we carry, with everyday objects for scale:
| Size range | Feels like | In inches |
|---|---|---|
| 3–5 mm | grain of coarse salt | 0.12–0.20" |
| 5–7 mm | sesame seed to mung bean | 0.20–0.28" |
| 7–9 mm | pea-sized | 0.28–0.35" |
| 9–12 mm | small beads & pea-sized pieces | 0.35–0.47" |
| 12–15 mm | dime-sized | 0.47–0.59" |
| 15–20 mm | cherry-sized | 0.59–0.79" |
Quick reference: a US dime (17.9 mm) is wider than most 12–15 mm chips, while a penny (19.05 mm) is close in size to a 15–20 mm chip. A quarter (24.26 mm) is wider than all the chip sizes we carry.
2. How much do I get? 100 g in real pieces
Chips are sold by weight, and 100 g ≈ 3.53 oz. Because a bigger chip weighs more, the piece count drops fast as the size goes up. All four piles below are exactly the same weight and were photographed at the same camera distance, so what you see is a true side-by-side comparison:
| Chip size | Pieces per 100 g | What it suits |
|---|---|---|
| 5–7 mm | 450–550 pcs | resin casting, candle tops, tiny bottles, shaker fills |
| 7–9 mm | 150–170 pcs | bracelet & jewelry filling, small planters, pockets |
| 9–12 mm | 90–100 pcs | decorative bowls, aquariums, display trays |
| 12–15 mm | 35–45 pcs | palm-stone accents, statement jars, single-piece details |
Counts are ranges, not promises. Density changes from stone to stone, and a flat flake weighs less than a chunky nugget of the same width. Order by weight, plan by range.
3. Which chip shape should I choose?
Shape is the one thing we cannot guarantee as a filter — it is decided by the stone type and by the batch. In practice you will meet three shapes:
- ROUNDED NUGGET — chunky, rounded shapes. The most natural-looking of the four; ideal for decorative bowls, planter tops, aquariums and displays where you want volume.
- IRREGULAR — flat faces & defined edges. Those flat surfaces sit flush, so this is the best pick for resin embedding, mosaics and geometric layouts.
- FLAT — thin, flat flakes. Light and easy to glue, perfect for jewelry settings, thin-layer crafts, cards and bookmarks.
Note on the third photo: the pale aquamarine chips are shown in hand — very light stones disappear against white paper, and the hand doubles as a scale reference.

## Crystal Chips in Art & Creative Projects
Crystal chips are not only used as decorative fillers. Their natural variation in color, size, and shape also makes them a versatile material for creative and mixed-media artwork.
1. Crystal Chip Mosaic & Canvas Art
Use crystal chips to create abstract patterns, flowing designs, landscapes, and decorative compositions by gluing them directly onto canvas or other surfaces.
Smaller chips are particularly useful for detailed areas and smooth color transitions, while larger chips can add texture and dimension.
2. Floral & Botanical Crystal Art
Crystal chips can be arranged to create flower petals, leaves, stems, and complete floral compositions. They can be used to create decorative flower arrangements in vases or botanical-inspired artwork.
Combining different crystal colors, sizes, and shapes allows artists to create layered petals and textured floral designs.
3. Resin Art & Decorative Crafts
Smaller crystal chips are widely used in resin art, candle decoration, miniature projects, terrariums, decorative bottles, and other DIY crafts.

Start with size if you already know your project. Start with shape if you already know your look. And if you’re stocking a shop, buying larger quantities can help reduce your cost per piece.
