I made these a while back and wasn't able to sell any of them. Each ring is genuine sterling silver with 10mm cushion crystals set in them. Crystals are in dark Blue AB which has some purple to it in certain light, Clear AB, Mint green, Sage green, Lagoona blue, AB-ish color, Red, Pink and Vitrail. Very cute. Each ring is size 7. Not sizable. ( I have multiples of the Red, clear AB)
