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.
The famed old Spinel locality of Amity was one of the first of the Eastern USA Classic locales. The exact original locality may be lost today but the Skarns in the area have yielded some nice Spinels from time to time. This is an older piece with fine octahedral Spinel crystals on a crystalline orange Chondrodite matrix. Ex Hladysz collection, this has sharp form, nice arrangement and excellent luster with no damage. Displays very well from several angles and better in person.
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.
Spinel - classic old locale
Amity, Orange County
3.3 x 3.2 x 2.6 CM (miniature)
Post Tucson 2015
A very good example of Amity NY Spinel that was world famed when first found in the 1840's. The exact locale is now lost today, but occasional small finds are made in the area. This is an old specimen in fine condition, sharp, complete and with a nice contrast to the matrix.
Gigantic stacked red-purple octahedrons in symmetrical position. The color is good the luster is glossy and there are even some gemmy zones. The largest distinct crystal face is 7.3 CM across and shows triangular hoppering. For the size this is a very impressive specimen and is from the early finds over 20 years ago.
A purplish-red large Spinel twin over 5 cm across is the base for a smaller octahedron and some additional crystals. Shows typical etched surfaces and has some very glassy faces. An attractive display piece that is also quite instructive, it presents the twinning in a textbook form with a non twinned example as a contrast.
Sharp. lustrous and with deep purple-red color, this is a fine Spinel with strong form. Gemmy with glass-like surfaces, the transparency is above average for such a large crystal. The faces alternate from a melted or rounded form to sharp prismatic. The crystal shows well "spinel twinning" and is exceptionally sharp for its size. No damage, displays well.
Deep red Spinel (spinel twinned) with good sharrp form, A very eyecatching thumnail, that is not quite a true gemmy transparency but is translucent on the edges. The color of this one is far better than most and the form is distinctive. Attractively priced too.
