How to take good care of gemstone DND DICE and glass D&D DIC

I don't use gemstone dice, but I do have a decent crystal collection a few of which are commonly made into dice. I'll add onto the advice of the blog, it will at least apply the gemstone dice.
I'd say it's also best is to make sure you have some sort of mat you're rolling on to, as some gemstones aren't as hard as others and this may help to prevent chipping. As mentioned avoid water, depending on the gemstone some will eventually breakdown when in prolonged contact with water, others can actually leak chemicals when wet as well so it's best to avoid using water and soap as a primary cleaning method if you're wanting to remove oil buildup, or anything sticky that got on your dice. Instead I recommend a spray mixture 1 part witch hazel 1 part water. Lightly spray the dice and immediately wipe with a soft cloth, make sure they are completely dry after. Hope this helps.
