Extremely Rare Polyhedral Agate - Brazil (1970s) across the Bering Land BridgeTo have an agate specimen similar to this in your collection is something special to say the least. Most of these agates that have found their way on the market have either been gobbled up by private collectors or cut into many slices to maximize profit. Do not miss your chance at a such a rare mineral specimen! Unlike many of the other specimens in our galleries, this piece has very defined crystal formations in the center! Size: 3. 41 x 2. 70 x 0.
