Sadly I could not find a way to take a photo that shows just how glorious these dice look in actual use. (I'm not exactly a professional photographer.) These are a set of gaming dice cut from dichroic prisms. This makes them sparkle in unusual ways and colours that makes them unique of all the dice I own. They're instant eye-grabbers on the table.
I have a set of these from I think wyrm wood. They are unreasonably expensive and I never would buy glass dice for that price, but it was a birthday gift.
I did manage to almost replicate it by putting dichroic window film on a set of blanks and then putting clear over that. They are not as nice but they are some of the best dice I’ve made.
