BURMESE RUBY
one of the most favourable origins for rubies
Among all kinds of colored gemstones, ruby is the most expensive gem variety, among which Mogok (Myanmar) is one of the most favourable origins for rubies. For hundreds of years, rubies had held a supreme position in the East. The best proof of this is the Sanskrit nicknames for rubies: Ratnaraj and Ratnanayaka, meaning ‘king of gems‘ and ’chief of precious stones‘ respectively. Ruby‘s color is determined by the trace element ’Cr‘, and color is the most essential factor when it comes to market value for rubies. The most desirable rubies possess the purest vivid red or with a very slight purple tone, known as ‘pigeon blood red’.
PIGEON’S BLOOD
In the international gemstone industry, the authoritative appraisal agency SSEF (Swiss Jewelry Research Institute) and Gübelin (Gübelin Laboratory) have a strict unified grading standard based on color and quality for the use of ‘pigeon blood red’. To be classified as so, the rubies must be rich, saturated, and uniformly bright red, with no distinct secondary tones (such as blue or brown), and a very subtle purple tone is acceptable. Its three specific indicators: tone, saturation and lightness, must refer to the authoritative appraisal institution ‘standard colorimetric stone’ for grading assessment. Its body color should show strong fluorescence under UV irradiation. The fluorescence is caused by the higher chromium content and the lower iron content, which makes the ‘pigeon blood red’ gemstone seem to have energy flowing out from within.
