I can't deny that these dice are insanely pretty, the light refection is just stunning to behold, and they feel really nice in your hand. However, functionally, they aren't great. The numbers are really hard to read, you either have to lean in close, or pick them up to tell what number you rolled. Like I said, they're pretty, but they're designed to go on your shelf and be part of your collection, rather than being part of your game, which is a shame.
Even more stunning in person, these dice diffract light internally meaning they change colours like precious opals *and* look like they are glowing from within! The etching is beautiful and makes then easier to read. Would recomend a dice tray with this set, they are far too pretty to risk getting scuffed or damaged
