Sodalite var: Hackmanite Outstanding World-Class Incredibly Large Rare Orange Color Fluorescent/TenebrescentHere we have an exceptionally rare and truly mind blowing faceted gem of Hackmanite, the gem variety of Sodalite, which is best known for not only its beautiful colors and transparency, but the extraordinary visual phenomenon of fluorescence and tenebrescence exhibited when the material is exposed to ultra violet light. Hackmanite typically fluoresces a strong hue under long wave ultra violet light, and typically a softer hue under short wave

this highly aesthetic display piece is from Jefferson County

graceful hydrothermal etching patterns

"sword"-shaped crystals of Vivianite with a bit of attached red altered sandstone from Tomokoni

but the piece in general is in very good shape

Here we have an interesting and rarely seen Cassiterite from Sakangyi

The underside of the specimen shows the hollow

It's important to mention that in our experience

These crystals have a unique appearance with compressed prismatic form

amazingly well-formed cyclic twinned crystals are aesthetically intergrown with tan compressed rhombohedra of Siderite

A difficult specimen to photograph

Good green Garnet specimens are rarely seen in pieces this size

and is notably transparent (GEM QUALITY)
