Hellyerite, Heazlewoodite, Zaratite Locality: Lord Brassey Mine, Heazlewood district, Tasmania, Australia (Locality at mindat.org) Size: 10.4 x 7.8 x 4.4 cm. A very rich, very rare and fine cabinet specimen from Tasmania. The rich, emerald-green coating of the rare nickel carbonate, zaratite, hosts powder-blue hellyerite and light bronze heazlewoodite. Hellyerite is a rare nickel carbonate and heazlewoodite is a rare nickel sulfide and the Lord Brassey Mine is the Type Locality for both species. The matrix also contains chromite. The Lord Brassey mine is an old abandoned nickel mine. You do not see much available. Older, exceptionally rich and rare combination material. Mineral

Helvite Locality: Wushan Spessartine Mine, Tongbei, Yunxiao County, Zhangzhou Prefecture, Fujian Province, China (Locality at mindat.org) Size: 3.5 x 3.1 x 1.3 cm. The helvite sits at the junction of a sculptural cluster of feldspar crystals, attractively accented by muscovites. This helvite crystal has superb luster, a sheen almost metallic in nature. It is 1.5 cm across at widest, and presents fully and dramatically front-and-center. The little freestanding accent crystal is itself about 8 mm. Mineral

Henmilite Locality: Fuka mine, Bitchu-cho (Bicchu-cho), Takahashi, Okayama Prefecture, Chugoku Region, Honshu Island, Japan (Locality at mindat.org) Size: 4.2 x 3.4 x 2.8 cm. An altered, lightweight, white, volcanic rock, hosts dozens of glassy and gemmy, deep purple-blue crystals, of henmilite, with crystals reaching .35 cm across. Henmilite, first discovered in Japan, is a very rare calcium, copper, boron hydroxide. This is a superb miniature of high quality from a remarkable find at the type locality, long thought unproductive, about 5-6 years ago. Mineral
