I've been working with a customer in the UK for some time trying to create his dream set of Tahitian pearls for his wife. The request: top-gem, Tahitian pearls, dark bodycolor, strong peacock overtones.
The strands ranges from just over 9 to 10 mm. The bracelet is in the 8-9 range, and the earrings are nearly 11 mm. The customer I made this for bought the pair of intense peacock Kamoka pearl earrings a couple months back. He wanted a set that were the same color, but those pearls are really difficult to come by in rounds.
