Topaz

specimen number:
9731009

location:
Sakangyi, Kyauk-Pyat-That, Mogok, Mandalay, Myanmar

description:
Superb glass gem quality sharply formed crystal of topaz. In super condition. The crystal weighs 107.66 g.

The Sakangyi pegmatite field, located near Kyauk-Pyat-That within the famed Mogok Stone Tract of Mandalay Region, Myanmar, is host to gem-bearing granite pegmatites that intruded the Miocene Kabaing granite body along the Mogok Metamorphic Belt. These miarolitic pegmatite bodies formed during late magmatic evolution as volatile-rich fluids cooled and produced large open cavities, generating ideal conditions for growing exceptional gem crystals. Historically mined for over a century through both primary hard-rock excavations and secondary alluvial or colluvial gravel workings, the locality has achieved international renown among mineral collectors. While the area is globally celebrated for producing giant, world-class colorless to sherry-colored topaz crystals, it is equally prized for fine aquamarine beryl, morganite, schorl tourmaline, smoky quartz, and microcline feldspar matrices.
