Rocks and Talks
On Saturday, we went down to Albuquerque for the Treasures of the Earth Gem and Mineral show. They have great silent auctions, my hubby even got into the bidding! We picked up some awesome specimens for our collection for next to nothing.
The fluorites for $2, 3 and $4. I like fluorite, can you tell?
This massive herkimer diamond for $4.
Aaannd…these little beauties for $16. Also herkimer diamonds, which aren’t really diamonds at all, but rare and special. Wikipedia says this about them:
Herkimer diamond is a generic name for a double-terminated quartz crystal discovered within exposed outcrops of dolostone in and around Herkimer County, New York and the Mohawk River Valley. Because the first discovery sites were in the village of Middleville and in the city of Little Falls, respectively, the crystal is also known as a Middleville diamond or a Little Falls diamond.
Herkimer diamonds became largely recognized after workmen discovered them in large quantities while cutting into the Mohawk River Valley dolostone in the late 18th century. Geologists discovered exposed dolostone in Herkimer County and began mining there. The popularity of mining for double-terminated quartz in the Herkimer County outcroppings is what led to the name, Herkimer diamonds. Currently, Herkimer diamonds can be found in large quantity in at least Herkimer, Fulton, and Montgomery counties, and double-pointed quartz crystals have also been found in abundance in Tibet and Afghanistan, as well as in other countries.
These quartz crystals, which geologists theorize formed extremely slowly in small solution cavities or vugs, have 18 facets (6 sides) and two terminations. There are also larger cavities that are several feet in diameter that are called “pockets”. Herkimer diamonds are found clear, cloudy, smoky or even containing a variety of rare impurities. Impurities (rare and general) can include clusters, scepters, fluid inclusions (sometimes incorrectly called enhydros), phantom, and bridge crystals. A fluid inclusion is a pocket within a crystal containing liquid, usually water, sometimes also methane or oil, and rarely, smaller crystals. A phantom is a crystal containing other visible crystals of the same type, a skeletal crystal contains a series of crystal edge outlines inside the crystal and a hopper crystal has its faces replaced by a step like pattern.
I got to visit some friends including my bestie, Tamara. She crocheted a bed for my bengal, Hootie. He absolutely loves it and guards it from our other cat.
