SOLD Corundum var. Ruby
stock #SOLD 19.1-804
4.2 x 2.8 x 2.6 CM (miniature)
new year 2021
A distinct vivid red Ruby on matrix from Tanzania. The specimen is repaired (re-attached to the matrix) but the Ruby is undamaged and doubly terminated. Moderately translucent, the form is more distinct and better exposed than most from this region. Vividly fluorescent, the repair helps keep the cost low. Ex John Buckley collection, his specimen number is painted on one edge but can be removed if desired.
A single doubly terminated Corundum crystal that shows classic form and habit. This is vividly fluorescent an intense red which is normal for Ruby. The terminations are flat, smooth and have some intersecting lines visible. The crystal faces have typical very rough texture. Strong light penetrates the sides of the crystal showing some degree of translucence. Older specimen (1960's vintage) with nice form and great fluorescence.

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.
