This is a very dressy vintage ring, which is made of 9 carat gold and is set with a cluster of tanzanites, which surround a central opal. There are 18 tanzanites in total, 8 drop-shaped larger ones and 8 smaller round ones. The opal in the centre is basically white with just the faintest pixels of light blue, so as not to take away from the sparkle of the tanzanites. The entire ring face is 1.5cm in diameter. The inside if hallmarked as 9 carat gold for Birmingham, with an additional stamp of 9K, but there is no date letter. The ring is presumably fairly modern. It is size O and is in excellent condition.
