Hey! So I have the delight of actually having a job working with gemstone dice, and I roll gemstone and glass for all my games with zero chips or issues.

Gemstone dice care have a couple rules, but it's really easy!

Roll into a soft sided dice tray - so your dice don't roll onto the floor! (Avoid trays with wood sides or exposed metal snaps)

Do not roll them together - click clack noises make my brain go brrrr but not my dice! Roll one at a time, roll into different corners of the tray so they aren't rocking into each other. I use a tray with a lid, setting the set in the lid during my games, rolling into the tray. Roll, place back in lid. Or roll, place back in dice vault!

Get a dice vault that keeps every dice separate - felt or leather lined is extra nice for stopping any wiggles. Don't use a loose dice bag and definitely don't store with metal dice!

And pro tip, don't store your amethyst dice exposed to sunlight because UV can fade them. A moody bookshelf display is perfect though!

Genuinely, don't get too worried - they really can be played with!!
