The stone is doing things your resin gets blamed for

You poured a clean batch. The clear quartz vanished into the resin like it was never there. The chips drifted to the bottom of the mould. Something porous burped bubbles across the surface overnight. A customer left a suncatcher in a south window for a summer and the amethyst came back grey.

None of that is a resin problem, and none of it is bad luck. It is material behaviour, and it is knowable before you pour.

Clear quartz disappears in clear resin because their refractive indexes nearly match — quartz 1.544–1.553, cured epoxy around 1.55–1.60. The stone is still there. Light just stops noticing it.

That is the sort of thing a supplier should tell you and almost none of them do. So the table below is the one we would have wanted when we started: every stone we sell in volume, and how it behaves in the thing you are actually selling.

What each stone does in the thing you are selling

Mohs hardness from standard gemmological references; fade and solubility notes from GIA and the International Gem Society; dust hazards from OSHA. Where the crystal internet and the mineralogy disagree, we went with the mineralogy.

Stone Mohs In resin In a sunny window Around water Dry sanding / drilling Maker's verdict
Clear quartz 7 Goes nearly invisible Stable Fine Silica dust Let points sit proud of the surface instead of drowning them
Amethyst 7 Good, stays visible Can fade in strong light Fine Silica dust Great in resin, wrong for a permanent sunny window
Rose quartz 7 Good Generally stable (GIA) Fine Silica dust The “rose quartz fades” rule is a myth — it is the rare pink quartz that fades
Citrine (heat-treated) 7 Good Can fade in strong light Fine Silica dust Almost all citrine is heat-treated amethyst. Label it, keep it out of the window
Black tourmaline 7–7.5 Excellent, opaque Stable Fine Wet-cut The safest dark stone for anything that lives outdoors
Obsidian 5–5.5 Excellent, glossy Stable Fine Sharp edges Volcanic glass. Beautiful in resin, chips can cut — wear gloves when sorting
Agate / carnelian 6.5–7 Excellent Natural colour stable Fine Silica dust Slices are the workhorse of coasters and suncatchers
Dyed agate slices 6.5–7 Excellent Dye can fade Fine Silica dust Natural agate colour does not fade; the added dye can. Disclose it, keep it indoors
Fluorite 4 Good, watch deep pours Some fade Never submerge Cleaves easily Slightly water-soluble and heat-sensitive from about 100 °C. Not for coasters
Selenite / satin spar 2 Only fully encapsulated Stable Dissolves slowly Soft, scratches About 2 g/L soluble. Fine sealed in resin, never in anything that meets a wet glass
Malachite 3.5–4 Good, stunning colour Stable Avoid Copper dust — high hazard Gorgeous and the one stone we would never dry-sand. Wet-cut or leave whole
Tiger's eye 7 Good, great flash Stable Fine High hazard dust Never dry-sand or dry-grind it
Pyrite 6–6.5 Good Stable Corrodes in damp Wet-cut Keep it dry and fully sealed or it will weep and stain over time
Lapis lazuli 5–6 Good, porous — seal first Stable Brief only Wet-cut Seal-coat before embedding or it will bubble on you
Howlite (often dyed blue) 3.5 Good, very porous Dye can fade Porous Soft Dyed howlite is sold as “turquoise” all over the internet. We label ours
Angelite 3.5 Good Stable Converts to gypsum Soft It is anhydrite. Water changes the mineral itself — keep it dry

Rule of thumb that covers the rest: fully encapsulated stone is protected; any stone left proud of the surface lives with whatever your customer does to the product. Soft (under Mohs 5) and porous stones want a seal coat before they go in.

What to buy, by what you make

Chips are sold by weight in graded sizes, so the same order is the same size next time. That is the difference between a craft supply and a production input.

Which chip size, and what it costs per piece

Approximate piece counts per kilogram, from our own chip sizing chart. Divide your bag price by the count and you have the number most makers never work out: material cost per finished piece.

Grade Piece size Pieces per kg What it is for
Crushed mini Sand to 3 mm Thousands Geode resin fill, jar layers, inlay
Tiny 2–10 mm 150–240 Spell jars, bottle fill, small resin work
X-Small 3 mm–1 in 100–160 Keychains, charms, scattered resin pieces
Small 0.5–2 in 50–100 Wrapped pendants, focal chips, trays
Medium 1–2 in 20–50 Statement pieces, wands, larger decor
Large 1.5–3 in 8–20 Display pieces and one-offs

Worked example: a 1 kg bag of tiny chips at a listed $20 with roughly 200 pieces is about 10 cents of stone per piece. If that stone is the hero of a $22 keychain, your material anxiety is not really about the stone.

What we do not sell

So you can plan the rest of your supply list. We would rather say it here than have you find out at checkout.

Resin, moulds and pigments

We sell the stone that goes in them, not the chemistry. Buy resin from a resin specialist and keep your supplier relationships clean.

Findings, wire and keyring hardware

We carry stretch cord and waxed cotton cord, plus coil cage pendants and pre-set pendants — but no jump rings, no wire, no blanks.

Glass prisms

Most “crystal suncatcher” kits are cut glass. We sell natural quartz points, slices and chip strands instead, which is a different look and a different story to tell.

Cabochons

Not stocked. Drilled points, drilled tumbles, slices and pendants cover most of what people want cabochons for.

Where makers buy stone, and what it costs them

An honest look at the alternatives, including where they beat us.

Where you buy Consistency between orders Minimum What it costs you
Stonebridge wholesale Graded sizes, weekly restock, live inventory None You apply once and pay before it ships
Marketplace listings Varies by seller and by batch None Highest cost per gram of the lot, and the grade drifts between orders
Flat-rate bulk sites Usually one grade, one price Often per-style packs A single price per kilo no matter the stone — you overpay on common material
Offshore direct Good if you can inspect 50–500 pieces per stone Weeks of transit, customs, and cash tied up before you know it sells

If you need one unusual stone once, a marketplace is genuinely fine. Wholesale earns its keep when the same piece has to exist a hundred times.

Frequently asked questions

Real questions from makers, answered properly. Marked up with FAQ schema so search engines and AI assistants can quote them.

Buying and wholesale

Where can I buy crystal chips in bulk in Canada?

Here, from an Ontario warehouse. We stock 150+ chip varieties in five graded sizes plus 1 kg production bags, ship in 2–5 business days to most of Canada, and there is no minimum order. Because we import directly rather than reselling, 1 kg chip bags list from about $9 to $40 depending on the stone, before your wholesale discount.

Do I need a business number or tax ID to buy wholesale?

No tax ID is required. You tell us what you make and where you sell it — a market booth, an Etsy shop, an Instagram page or a storefront all qualify. Approval usually takes under one business day.

Is there a minimum order?

None, and no per-style minimums either. That matters in this category: several bulk suppliers require five bags per style, which forces you to gamble on a stone before you know it sells.

Can I sell products I make with your crystals?

Yes. That is what wholesale is for. There is no licensing, no royalty and no restriction on selling finished goods you have made from stone you bought here.

How do I know the chips are real and not dyed or glass?

Our listings say so. Anything dyed, heat-treated or lab-made carries “Enhanced” or an equivalent note — dyed agate slices and enhanced citrine, for example. Trained gemologists check shipments in Kitchener. Dyed material is legitimate to sell; selling it as natural is not.

Will the next bag match the one I ordered last time?

That is what the grading is for. Sizes are sorted to a published spec and restocked weekly with live inventory on the site, so a repeat order of the same grade behaves like a repeat order.

Resin technique

Can you put crystals in resin?

Yes — stone does not dissolve or react in epoxy. The three things that go wrong are optical (clear stones disappear), physical (stones sink) and chemical (porous stones release air and moisture). All three are preventable, and the table above says which stones do what.

Why did my clear quartz disappear in the resin?

Because quartz has a refractive index of about 1.544–1.553 and cured epoxy sits around 1.55–1.60. When two materials bend light almost identically, the boundary between them stops being visible. Use coloured or opaque stone, or let the point sit proud of the surface.

How do I stop chips sinking to the bottom of the mould?

Pour in layers. Let a base layer gel until it is tacky, place the stone, then pour over it. Stone is denser than resin, so anything poured in one go will settle — that is physics, not a resin defect.

Why do my stones make bubbles in the resin?

Porous stone holds air and releases it once covered. Druzy, geode, lava, howlite, turquoise and lapis are the usual offenders. Brush a thin seal coat over them, let it go tack-free, then embed.

Do I need to wash the chips first?

Wash them, then dry them completely. Dust makes a dull surface and moisture makes a hazy, cloudy cure. Damp inclusions are one of the most common causes of resin that “went cloudy for no reason”.

Will UV resin cure underneath opaque crystal chips?

No. UV light travels in straight lines, so anything sitting in the shadow of an opaque stone stays soft. Cure in thin layers and flip the piece, or use a two-part epoxy for anything thick.

Does the heat from curing resin damage stones?

Deep pours can reach 50–120 °C. Most quartz-family stones shrug that off, but dark fluorite can lighten from around 100 °C, and cleavage-prone stones dislike fast temperature swings. Pour soft or heat-sensitive stone in shallow layers.

Sun, water and safety

Which crystals fade in sunlight?

Amethyst, citrine, kunzite, some fluorite and celestite are the documented faders — GIA notes that amethyst and citrine colour “can fade with prolonged exposure to intense light”. Dyed stones can fade too, because the dye fades even when the mineral would not.

Which crystals do not fade, for suncatchers and window pieces?

Clear quartz, rose quartz, black tourmaline, obsidian, natural agate and carnelian, tiger's eye and most jaspers hold up in a window. That list is your suncatcher shortlist.

Does rose quartz fade in the sun?

No, despite what most crystal blogs say. GIA describes rose quartz as “generally stable when exposed to light and heat”. The stone that genuinely fades is the much rarer crystalline pink quartz, which is a different material sold under a confusingly similar name.

Which crystals cannot get wet?

Selenite and satin spar dissolve slowly at roughly 2 g per litre. Angelite converts toward gypsum with water. Fluorite is slightly soluble and should never be submerged. Pyrite corrodes in damp air. Everything above Mohs 6 with a non-porous surface is generally fine.

Can I use selenite in a resin coaster?

Only if it is fully encapsulated, and even then we would not put it under a sweating glass. A coaster is the single wettest product a maker sells. Use quartz, agate or jasper instead.

Is it safe to sand or drill a piece with crystals in it?

Not dry. Cutting, grinding or sanding quartz-family stone releases respirable crystalline silica, which OSHA links to silicosis and lung cancer and which the IARC classes as a Group 1 carcinogen. Work wet, or outdoors with a proper respirator. Malachite adds copper dust and tiger's eye is worse again. Finished, polished pieces are not the hazard — the dust is.

Which crystals are toxic to work with?

Handling stone is not the risk; making dust from it is. Malachite and azurite are rated high for copper dust, tiger's eye high for fibrous dust, and all quartz-family stones carry silica risk when cut dry. Nothing on our site is dangerous to hold, wear or sell.

Is it safe to put crystals in candles?

Stone is not flammable, but anything in the melt pool changes how a candle burns, and stones can crack, shift or get extremely hot. If you sell candles with stone on top, test-burn the design and keep stone out of the flame path. Our witch-shop page goes into this properly.

Pricing and selling

How do I price a handmade crystal product for a craft fair?

Standard craft-fair guidance is (materials + labour + overhead) × 2.2 to 3.0, and impulse items sell best between $10 and $40. The number most makers are missing is material cost per piece — divide your bag price by the pieces-per-kilo count on our chip sizing chart and it stops being a guess.

How much stone do I need per piece?

Roughly: a resin keychain uses a pinch of crushed or tiny chips, a coaster takes 20–40 g, a standard spell jar holds 15–30 g, and a wrapped-tumble charm is one stone. A 1 kg bag of tiny chips runs to roughly 150–240 pieces.

What sells best at craft fairs?

In this category, price point beats product: $10–$40 impulse items move, and wrapped tumbles, keychains, small resin pieces and spell jars dominate that band. Larger statement pieces are worth having on the table because they make the small items look like a bargain.

When should I order for holiday markets?

September. Ontario shipping is 2–5 business days year-round, but the stones that sell out are the ones everyone else is also buying in October. Ordering in September gives you time to make the stock, not just receive it.

Buy the stone like a production input

Apply once, get approved in about a day, and order graded chips, tumbles and points with no minimum. Ordering for the holiday market season? Most makers place their big restock in September.
