Spinel on Calcite (Ref: 22.1-161)
Mahenge, Morogoro, Tanzania
50mm x 33mm x 31mm
Fine rich red octahedrons of Spinel up to 2.4 CM across are well-exposed on contrasting white Calcite. The luster is quite bright and while the Spinel is not really transparent it is translucent and vividly fluorescent. These Tanzanian Spinels are in some cases an excellent alternative to more expensive examples from other locales. This piece shows very classic habit and the crystals have only a very slight hint of "melted" edges. Rounded or "melted" edges is typical of Spinel crystals as they get larger, this piece is notably sharper than typical.From: Well-Arranged Molecules
