Here is a great Barite crystal from South Dakota, great crystal shape, color, luster, and clarity! Would make a great gemstone, however I think best left as is. Would make a great addition to any USA collection! $75!

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
