Howardite cab ~
Offered here is a sweet cabochon of howardite (an unsual and rare form of opal silicated tuff), from northern Nevada. Sometimes called 'rattlesnake stone', it has delightful coloration and figure, reminding me of crazy venetian blinds or zippers, oddly enough. The darkest areas you see in the pic are actually highly translucent, giving the stone an amazing quality of depth. It has a very high rounded dome of 8mm, a powerful designer shape, and a slick glassy polish both front and back, with next to none of the typical undercutting.
Size: 55x17mm
Weight: approximately 47 carats
Price: SOLD See current gemstones for sale
