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...
