I really like this Torbenite from Spain. Very unusual to find a cluster of this material on the market. I love all the crystals clustered together on this piece. Discounted to $100!

25.25 Gram Wet Ethiopian Opal with a Phantom Opal egg in the center! For some reason this piece reminds me of a clam, and the phantom is a big pearl! A cool piece for a collection. Will be shipped wet! $150. Available on @over_100_dollar_gems
