Ruby- red Corundum
Ohngaing (Ohn Gaing; Ohn Kai)Mogok Valley, Mogok Township, Pyin-Oo-Lwin
3.1 x 1.1 x .9 CM (small miniature/ large thumbnail (toenail))
Rich red color Corundum crystal that is crude but complete and translucent throughout. Burmese (Mogok) Rubies are the most valued Ruby in the world and very few crystal specimens are available. This is a complex crystal with some etching (looks "melted" in spots) and recrystallization. Looks good on all sides, this is a sizable 24.5 Carat stone.

A big and sharp (2.7CM) main Ruby crystal is well exposed and nicely perched on the matrix. Very good color with some purple hues seen in some lighting that indicates that the core of the crystal may be a blue Sapphire. The crystal habit is the rare flattened habit with one overdeveloped face that dominates the prism. In fine condition with excellent esthetics, this also shows the crossing lines of inclusions that cause a star reflection on the terminations.
A rich red Ruby crystal that is transparent, has a slight color zoning and more purple core. This stands nicely from the encasing Calcite matrix. A second corundum crystal on the backside is broken and more blue, it is not seen from the display side. There is one clean repair that is not seen without help of 20X magnification, otherwise the Ruby is perfect and complete. The crystal is partially enclosed on the calcite with 1.9 CM exposed and seems to be about 2.8 CM overall. Very fine form and color, Mogok Ruby has been regarded as the best in the world for centuries, yet few good specimens are seen. Mined in 2016, it is now illegal to export uncut gems from Mynamar.
