Quartz (var: Ametrine) (superb large crystal) (2,075 grams)

Item Description

Ametrine is a unique and beautiful variety of Quartz, and the finest examples are found in the eastern Bolivian jungle. This material is a completely natural purple and yellow bi-color variety of Quartz (AMEthyst + ciTRINE). The crystals get their bi-colored appearance as distinct triangular sections form on opposing rhombohedral faces of the crystals. When the Ametrine crystals are sliced across the "c" axis, you can see the classic "pinwheel" or "radiation" pattern that is well known in this material. The vast majority of gemmy Ametrine crystals are severely etched and it's incredibly rare to find euhedral crystals. Here we have a very large, incredibly sharp, well-formed, thick hexagonal crystal with good internal gemminess showing a mostly purple interior, but you can clearly see small sections of yellow when the termination is backlt. Not only is this a monstrous Ametrine crystal, but the fact that all six pyramidal faces on the piece are increcibly smooth and sharp is RARE for this material! The rest of the prism faces on the piece are layered or "built up", but and eventually the color transitions inside the crystal from a purple hue to a nearly white tone. A very cool, rare and superb example of this material only found in one place in the world in crystals like this! Weight = 2,075 grams. If the crystal were to be sold as carving rough, it would be around $2/gram, so it's EASILY valued at $4,150 based upon the value of the gem rough alone. PLEASE NOTE: This piece is large and heavy and it will require an additional shipping charge. Please keep this in mind when bidding and feel free to contact us with any questions or concerns.
