Burmese Gems - Overview
Introduction to Myanmar's legendary gem production from Mogok and other regions, including ethical considerations.
Introduction
Myanmar (Burma) produces some of the world's finest gems. The Mogok Stone Tract
in Mandalay Region has been mined for over a thousand years and remains the global
benchmark for ruby quality. [1] "Pigeon blood" (vivid red
with a slight blue modifier and strong UV fluorescence) was coined specifically to
describe ideal Mogok ruby and is now applied by laboratories to exceptional stones
regardless of origin. [1]
Diagnostic significance derives from Mogok's marble-hosted geology. The low-iron
environment allows chromium fluorescence to dominate, producing the strong red glow
under long-wave UV that distinguishes Mogok ruby from iron-rich, fluorescence-suppressed
basalt-hosted material. Short rutile silk, calcite crystals, and negative crystals
with fluid typify the Mogok inclusion suite.
Beyond ruby, Mogok produces exceptional sapphire, red and pink spinel, and peridot;
Kachin State supplies the world's dominant jadeite output; Mong Hsu provides volume
ruby requiring heat treatment. US sanctions, active 2008–2016 and reinstated 2021,
make compliance a live issue for buyers in regulated markets.
