Spinel- Gem octahedron
Pein Pyit (Painpyit), Mogok, Sagaing district
1.5 x 1.3x 1.2 CM (thumbnail)
Transparent, blood red and complete. A single octahedron of Spinel from the famed Mogok gem field. The edges show typical rounding or "melted look" that is classic for this area. These are extracted as gem gravels by hand work as has been done for centuries. Since the mineral is so hard and abrasion resistant the form stays relatively sharp and lustrous. with 10-20 x magnification only slight signs of abrasion can be seen. 16.8 Carats in weight. A nice colorful octahedron of "ruby" Spinel.
Spinel -Classic old locale

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 symetrical 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. lusterous 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.
A sizable old location piece with a Dr. Krantz in Bonn label (a little different than most Krantz labels we have seen) there are several sharp octaherdral crystals etched from a calcite matrix. This is not a highly esthetic piece but it is a classic vintage and it does show the blue to purple octahedrons well.
