Gordonite, Wardite Locality: Rapid Creek, Dawson Mining District, Yukon Territory, Canada (Locality at mindat.org) Size: miniature, 5.6 x 3.7 x 1.1 cm Wardite with Gordonite This is NOT one of the new wardites, but rather a more typical one in here both because it is unusually good as well for what it is, and to contrast the typical coloration to the new ones. These are SUPER-SHARP and LUSTROUS , and its really uncommon to get so many good crystals on matrix like this, and in good condition. The small yellow specks are actually eye-visible crystals of the rare species Gordonite and actually this piece is about the richest you can hope to get of that species...it richly covers the front and back, both.
