Rare Trapiche Habit Rubies, Sapphires and Emeralds!!

                        

The Trapiche habit is only seen in a handful of species around the world. Famously the term is often associated with Emeralds from Colombia, and in recent years some very attractive Rubies and Sapphires have been found in Myanmar (Burma). These specimens are beloved by collectors for their unique "six leg" spoke form that is reminiscent of "star" gems, but almost in reverse, as they required backlighting to see the dark black internal "spokes". We have been big fans of this material for a long time, and have slowly been putting together enough stones to create an update. Our sources in Colombia and Myanmar have been able to directly supply us with some fine examples of these gorgeous specimens. If you've never seen Trapiches before, or if you've always wanted to pick one up for your collection, don't miss out on these attractive and one-of-a-kind specimens. Truly no two are ever alike, and what they lack in size they more than make up for in beauty.
