Gemstone dice aren’t resin. They’re prettier – and more fragile.
If you’ve spent a decent amount of money on a set of natural gemstone or art glass dice, you probably want them to last for years – not shatter on their first drop.
This guide has no sales pitch. Just real-world advice on how to use, clean, store, and avoid that heartbreaking “crack” sound.
Universal rules – for every gemstone dice set
These rules apply no matter if your dice are amethyst or opalite.
1. Always roll on a dice tray. No exceptions.
Hard surfaces – wood, tile, glass – are killers. Gemstones and glass are hard but brittle. One drop can chip or even split a die.
Get a dice tray with felt or leather lining. It’s cheap insurance.
2. Don’t lend your dice to just anyone.
Not because you’re mean. Because other people might not handle them like you do. Especially anyone with metal dice – metal + gemstone on a hard tray is a disaster waiting to happen.
3. Avoid extreme temperatures.
Don’t leave your dice in a car in summer. Trunk temps can reach 60–70°C (140–160°F). Thermal shock can crack stones. Also keep them away from heaters, radiators, and freezers.
4. Store separately – away from metal dice.
Metal dice have rough surfaces that can scratch gemstones. If you own multiple sets, use a storage box with individual soft compartments.
Natural gemstone dice care (by material)
Different stones have different personalities. Let’s go through the common ones.
1. Amethyst, Tiger’s Eye, Red Jasper, Howlite (quartz family)
Hardness: 6–7 – fairly tough.
Good: Not easy to scratch.
Bad: Hard doesn’t mean tough. Still breaks when dropped.
Cleaning: Use a dry soft cloth (eyeglass cloth works). Occasionally you can use a slightly damp cloth, but dry it immediately. No soaking.
Don’t do: Long soaks in water, ultrasonic cleaners. Soaking can make the surface go cloudy.
2. Lapis Lazuli
Hardness: 5–5.5.
Special: Deep blue with golden pyrite flecks. Sometimes the surface can be a bit powdery.
Cleaning: Do NOT wash with water. Dry soft cloth only. No alcohol, no hand sanitizer, no perfume.
Storage: Best kept in a small separate fabric pouch to avoid rubbing against other dice. Rubbing can cause surface powdering.
3. Fluorite
Hardness: Around 4 – very delicate.
Looks: Beautiful greens, purples, blues. But it’s soft and easily scratched.
Cleaning: Avoid whenever possible. If dirty, use a dust blower or an extremely soft brush. Try not to use water. Fluorite soaked in water loses its shine and becomes “frosty.”
Usage: This is one of the easiest natural stones to crack. If you own fluorite dice, roll them gently on a padded tray – no hard throws.
4. Moonstone & White Labradorite
Hardness: 6–6.5.
Special: They have cleavage planes – internal weak lines. A bad hit can split the stone along those lines. So they’re more impactsensitive than quartz stones of similar hardness.
Cleaning: Light wipe with a soft cloth. No chemicals. No water washing.
Storage: Separate soft pouch. Never toss them loose in a box with other dice.
5. Obsidian & Snowflake Obsidian
Hardness: 5–5.5, but extremely brittle.
Nature: Volcanic glass. When it breaks, it breaks like glass – sharp edges.
Cleaning: Dry cloth. If you use a damp cloth, dry immediately.
Important: Don’t let them knock against other hard objects. Impacts leave small white chips.
Strong recommendation: Use a dice tray with an extra soft mat, not just felt. Obsidian is truly fragile.
6. Organic gemstones (amber, coral – if you have any)
Very soft. Heatsensitive. Acidsensitive. Alcoholsensitive. Basically, treat them like museum pieces.
Cleaning: Only a dry microfiber cloth. No water, no cleaners. These dice are better for display than daily rolling.
Special cases & common myths
1. Can I clean my dice with alcohol?
Natural gemstones: Mostly no. Lapis and fluorite especially hate alcohol. Alcohol can seep into tiny cracks and even corrode some minerals.
Art glass: Occasionally you can use lowconcentration alcohol (e.g., 70%), but rinse with water immediately and dry. Honestly, plain water and a soft cloth works just as well.
Bottom line: Don’t overthink it. Water + soft cloth is the safest.
2. My dice just fell on the floor. What now?
Take a breath.
Inspect for chips, cracks, or white spots.
If nothing obvious, you’re probably fine. Just be more careful next time.
If there’s a small chip or nick – you can still use it, but don’t make it your “main roll” die. It’s now a bit fragile.
3. Can I do the salt water balance test?
The salt water test is for resin dice to check for bubbles. For gemstone dice – strongly not recommended.
Why? Natural stones have tiny microscopic pores and internal fractures. Salt water seeps in. When it dries, salt crystals remain inside the cracks, slowly widening them or even corroding the material. Not worth it.
4. Why do my gemstone dice look less shiny over time?
Oils from your hands, dust, and sweat build up. That’s normal – not damage.
The fix: wipe them regularly with a clean soft cloth. Natural stones have micropores. A quick wipe now and then brings back most of the shine.
Storage & everyday habits
Best storage: A softlined box with individual compartments – each die has its own “bed.”
Avoid: Hard plastic compartment boxes without padding. The dice bounce around and knock into each other, leaving tiny white marks.
Traveling: Put the dice box in the middle of your backpack, surrounded by clothes. Don’t put it at the bottom under heavy weight.
Rotate your sets: If you own several gemstone sets, use them in rotation. Don’t abuse one set every session. Give them rest.
Quick self-checklist
Once in a while, check your dice:
Fingerprints or oily look? → Needs a wipe.
Dust in the engraved numbers? → Dry soft toothbrush (no water).
Small white marks from bumping? → Store them separately, get a compartmented soft box.
Looking less shiny than before? → Clean and dry, usually fixes it.
A few honest words at the end
Gemstone dice aren’t consumables. They’re collectibles. They’re part of your tabletop ritual.
A little extra care, and they’ll stay with you for years.
Here’s the truth: Expensive doesn’t mean unbreakable. Care is what really matters.
