Corundum var. Sapphire
Mogok, Pyin-oo-Lwin District
2.5 x 1 x .9 CM (thumbnail)
A pair of Sapphire crystals are perched on each other showing perfect textbook form. This shows the classic habit with lightly frosted faces, translucent with some transparent gem areas. Almost colorless with a faint blue to yellow hue, this is complete, a floater and undamaged. A choice thumbnail with far better form than is typical.
A well formed Russian Sapphire cluster in rosette form that is well exposed on the Marble/Calcite matrix. The Corundum cluster is 3.2 M across and has a subtle color zoning. Contrasts well with the matrix, a clean and distinctive specimen.
From a little known Chinese locality, These Corundum crystals are well formed and similar but noticeably distinct from the better known Madagascar specimens. Individual crystals reach 1.6 CM and are a blueish hue in daylight but have a more purple-red look in some artificial lights. The color change is subtle but clear. In very good condition, the crystals are well exposed and have a small amount of translucency at the edges.
