This older specimen has the most intense glassy luster, high transparency, and internal limpid brightness that you could ever imagine in a Mexican amethyst. Its grape juice color has a clean and sharp "feel" to it, that just places it at the absolute top of its game. I have handled a thousand Las Vigas amethysts, and yet this one stuns me every time I hold it. It is really bright and stunning in a case. This piece is perfect and complete all around. It was in the collection of Bryan Sage, who left his collection by bequest to the University of Arizona in the 1990s. For its size, it is among the best examples I have seen of this otherwise common material.Joe Budd Photos
