Glassy octahedral crystals of Spinel from the famed gem regions of Mogok in Myanmar. At first glance this looks almost black but under good light the color is a blue to purple-red color in zones and the crystals are transparent to translucent. In person the luster is brilliant and the condition is also very fine. These crystals have the typical rounded or melted look in some places but are very sharp on most edges. Much of the Spinel from Mogok is vividly fluorescent red, this is not, but under long wave is an unusual pale green. 60.45 grams overall there are a few areas of gem clarity but most is included. A nice and very unusual Mogok Spinel.
Spinel on Quartz and Calcite
Pein Pyit, Mogok, Pyin-Oo-Lwin District
2.8 x 2.3 x 1.3 CM (small miniature/ large thumbnail (toenail))
Well exposed, complete octahedron of ruby Spinel perched on a sliver of matrix. A few tiny flecks pf Pyrite are present as well, but mostly this is about the deep red Spinel crystal. This has some of the typical pitting, rounded edges and adhering matrix but is otherwise a very pretty dark red gem crystal, There are a few small gemmy Spinel seen with magnification on the flat sides of the matrix, they are almost invisible by naked eye. Myanmar has a well deserved reputation for exceptional gem crystals, especially for Rubies. However for hundreds of years Spinel were often substituted for Ruby. The gem fields in Mogok produce far more Spinel than Ruby, and it has been increasing in acceptance as a legitimate and valued gem. This is a nice affordable crystal that is above average in quality.
