8.3" Polished Deming Agate Bookends - "Big Dig" Site, New Mexico
This is a unique pair of bookends made from Deming agate that was collected from the Big Diggins (also known a "Big Dig") site in Deming, New Mexico. It features a mixture of quartz and chalcedony (jasper and agate) formations that were cut perfectly to create this striking display.
The flat contact edges have been lined with felt. Each bookend varies slightly in size, one measures 8.3" tall, 4" wide and 1.8" thick while the other is 8.3" tall, 4.15" wide and 1.78" thick.

Chalcedony is any microcrystalline variety of silica composed of very fine intergrowths of quartz and mogánite: microcrystalline minerals have microscopic crystals that cannot be observed by the naked eye. Both quartz and mogánite have the same chemical formula SiO2 (silicon dioxide), but different crystal structures. When free from impurities, chalcedony is colorless and transparent. Depending on impurities present during formation, chalcedony can form in a wide variety of colors including red, yellow, green, blue, purple, grey, white, and numerous hues in between. Chalcedony is quite hard at 7 on the Mohs Hardness Scale: this matches its main component quartz, which is the benchmark mineral for the scale at 7.
