Quartz

I meet with several of the best miners of Arkansas Quartz several times per year. This piece is by far one of the best I've seen in years. It is a "burr," Quartz, which just means the Quartz is growing in a 360 degree fashion around a sandstone matrix. What makes this stand out is the largest crystal is a pristine double terminated crystal measuring over 11 cm (+4 1/4 inches). It also has penetrating crystals inside the center that adds significant character and depth. There are dozens more crystals, the second largest is over 8 cm (over 3 inches), all the points are in great condition without dings (one near the bottom out of about 35 got scuffed). There are two spots where you can see the matrix from where it was attached to the host rock. 

It displays nicely and weighs nearly 2 pounds (almost 900 grams).
