There is simply no way to adequately describe the beauty and brilliance in this large 20 x 18 mm Super Gem Triplet Opal. I purchased this stone from a good friend in Australia a few years ago and he was very reluctant to let go of it. I guarantee you wont find anything on the market that equals it, this is as good as it gets. We have set it in 14 karat gold, the pendant measures just over two inches high by one and three quarters wide.
