Quartz, Tabular, Stovall Trail, McCurtain County, Oklahoma, Dr. David London Collection L-254, Miniature 2.5 x 6.5 x 7.2 cm, $450. Online Sept. 30.
Sharp group of quartz crystals with no point of attachment showing both classic prismatic and tabular crystallography. Localized clay inclusions add nice contrast. A rare specimen from alpine-type quartz veins in southeast Oklahoma. In the words of Dr. London "The quartz veins in SE OK are alpine-type, which is why the quartz has so many habits: very low temperature, lower than veins near Hot Springs (AR)." A very aesthetic specimen in great condition. Self-collected by Dr. London in October 2001.
