“Electromagnetic Wave” Inclusion in Mong Hsu Ruby

Narint Jaisanit

Recently the author examined a vivid red 1.18 ct cushion-cut ruby. This ruby contained several inclusions, such as distinctive hexagonal zoning with a blue core, a cloud of snowflake-like particles, and ladder-like particles. These inclusions combined with chemical analysis indicated a geographic origin of Mong Hsu, Myanmar. Interestingly, fiber-optic illumination revealed an electromagnetic wave-like pattern of particles (see above). Although whitish particles are common in Mong Hsu rubies, this electromagnetic wave pattern is truly unique.
