Properties of Burmese Ruby
Apart from its spectacular color, Burmese Ruby is a highly durable gem with a hardness of 9 on the Mohs scale. The stone’s specific gravity is 4.00, and it has a refractive index of 1.76 – 1.78. Burmese Ruby’s birefringence is of 0.008.
Finding high quality, natural Burmese ruby gemstones that are over 1 carat in size is difficult due to their rarity. This rarity is one such reason why these gems come at extremely high prices.
Color
There is no denying the fact that Burmese rubies are not always flawless. The value of Burmese rubies gets affected by the subtle differences in their color and the inclusions that they contain.
Those gems that have highly saturated medium dark red tones are considered the best. Whereas, such rubies that are either too dark or too light red do not come at extremely high prices.
Cut
The cut of a Burmese ruby plays an important role in giving it the status of the best ruby gemstones ever. These gems are available in a variety of cuts.
But, cushion cut, oval cut, round cut and emerald cut are highly common cuts for these rubies that enhance their beauty even more. Other than these cuts, one can also get Burmese rubies to inheart cut, pear cut, briolette cut, and marquise cut.
Treatments
A Burmese ruby stone price also depends on the treatment that it goes through. The stone’s color can be enhanced using heat treatment. Such treatment also improves the transparency of the gem.
Heat treatments of Burmese ruby gemstones are almost permanent and treated Burmese rubies don’t really require special care or precautions during use.
Other than the heat treatment, low-grade Burmese rubies may also undergo fracture-filling treatment with lead glass. This also helps in improving the color and clarity of these stones.
Although extremely difficult, finding a red Burmese ruby that is pure, natural, high-quality and untreated is a valued possession and, thus, may command a high price.
Sources
