We decided to take one of our most popular twisted briolette pendants and slide it on to a genuine high quality leather necklace. The verdict: beautiful. Twisted briolette rubies are very rare and a huge amount of skill is required in cutting such a stone. This ruby is adorned with a single round cut diamond and set into solid gold. Single 15.25 ct ruby, 0.01 ct diamond, I-3/K. Twisted Briolette cut. Pendant suspended from 17\" genuine leather cord with gold lobster clasp.
