This pair of 16mm d6 dice that are called mother of pearl. Please note that's the name of the color, not the actual material used. They are swirled mostly blue with some white and a bit of light purple included and have silver pips.
The particular die in the photo are just two of the dice that I have ordered. Thus, the actual die that you receive will be the same colors but may have slightly different markings. No two dice will be exactly identical.
