Tsehay Mewcha, Wegeltena, Delanta Woreda, South Wollo Zone, Amhara Region, Ethiopia
Measures: 14.4 cm tall x 11 cm wide
Precious opals are a hydrated amorphous form of silica (amorphous meaning a non-crystallized solid), unlike crystalline forms of silica, which are classed as minerals. Australia is the locality most associated with precious opal. The precious opals of Ethiopia were only discovered recently in 2008.
Opals are formed over thousands of years when rain frees spherical silica particles from sandstone. These microscopic particles spread deep into underground cavities and are then compressed into a closely-packed interlaced structure. When miners bring them forth from the earth to the surface, sunlight travels through this microstructure creating the dazzling kaleidoscope of flashing rainbow colors that we see here.
This opal may be unique. The colors are like no other we have seen from Ethiopia. There are several names given to opal (Black Opal, Boulder Opal, Fire opal, etc.). This piece begins an entirely new genre - Candy Opal.

Seafoam Green Fluorite Crystal Mineral Specimen – Dongpo Ore Field, China
Located in Edison, NJ
This is an attractive example from the Dongpo Ore Field of China. The best Dongpo fluorites are known for translucent crystals with great form and an attractive light green tone. This is a prime example featuring three sharp, cuboctahedral crystals in a saturated, seafoam green tone. The fluorites have multi-stepped faces along their sides and central faces that are smooth, acting like windows into the translucent crystals. The crystals’ lustrous sheen further highlights their intricate structure. They have formed atop a contrasting matrix (host-rock) of bladed, beige dolomite crystals. The dolomite is sharp and has formed in dense intergrown rosettes. Peeking out from under the dolomite and fluorites is a shimmering matrix of druzy, white quartz that frames the piece overall. The juxtaposition of textures, colors, and species makes the already colorful fluorite crystals...
