Vintage 14k Yellow Gold Diamond and Alexandrite Ring Size 6

Vintage custom made one of a kind cluster ring. The center stone is 3 carats and a synthetic alexandrite that flashes blue and violet. This ring is in 14k yellow gold. It is a size 6 and the face of the ring is 3/4" in diameter. It has 16 genuine diamonds of different sizes. I do not have the carat weight, but there is easily a carat present. Diamonds are eye-clean and have nice white color. 

The alexandrite has a flat pavilion tip and it looks a bit chippy, but there is no way that it could get chipped in this setting as it is well protected. 

It weighs 7.4 grams. Marked 14k.
