Locality: Las Vigas, Veracruz, Mexico. Size Class: Large Cabinet. Collection: Schertz Collection. This is one of the finest pieces in the auction, in terms of what is on the modern market. Amethyst (purple quartz) from Las Vigas occurs in small pockets scattered throughout the nearby mountainous terrain. Few large plates are ever recovered in perfect condition, such as with this piece. It has no damage, no repairs, and with intensely colored and glassy crystals to 4.5 cm in length, it is a major specimen for the locality. 1890 grams. Similar pieces have sold recently for record prices, and one has to see this in person to understand why by viewing how fully beautiful and three-dimensional it is. No other locality produces amethysts quite like this. While it is impossible to tell when this came out of the ground, it is undoubtedly an older specimen and the private collection it was from, was assembled in the 1980s-1990s. This example is similar to a piece that sold for 70k at auction! Size 17.0 x 15.7 x 14.5 cm.
