Sterling silver ring with crystals

This ring has crystals set into the band all the way around. The band is quite thick and sturdy. The crystals are good quality. But, I cannot say what brand they are. They hold thier clarity and sparkle, and do not go dull....even when the ring is dirty. The three larger crystals are set in prongs. The others are set into the band. The ring has an RF stamped inside it. Country of origin is China.
