Howardite cab ~
Offered here is a small (by request!) but fascinating cabochon of howardite, from northern Nevada. This unsual and very rare form of opal in silicated tuff is sometimes called 'rattlesnake agate', for obvious reasons, and also bears a resemblance to open woodgrain. It has figure so unusual, once you see it, you'll never forget it. The pattern in this cab reminds me of crazy venetian blinds or zippers, oddly enough. The highly translucent 'holes' of agate give the stone an outstanding quality of depth. The stone has a high rounded dome, a strong symmetrical shield shape, and a glassy polish both front and back.
Size: 22x19mm
Weight: approximately 18 carats
