With gem production in ore producing areas around the world, including the declining of Myanmar, the presence of rubies larger than 5 carats should be a cause for celebration for gem collectors. The pair of 5.03 and 5.02 carats Burmese rubies are both classified as ‘pigeon blood red’ by SSEF; the incredibly matching colour and crystal makes it a true treasure in the market. The two center stones are grandly decorated by over 10 carats diamonds each, maximizing the extraordinary beauty of the rubies.
Ruby belongs to a mineral called corundum, and the ruby from Myanmar contains chromium, so it has a unique rich blood red, and also has red fluorescence, which makes the gem look like burning coal and can emit immortal fire from it. This 5.28 carat ruby ring is produced in Myanmar, a high-quality Ruby producing area. Its colour is pure and rich. It can show a unique touch of red of Myanmar Ruby under natural light. Combined with the above characteristics, it is reminiscent of power and protection, life and blood, fire and enthusiasm, Ruby has been favoured by the most important collectors in history since ancient times. Both Mughal emperors and European nobles and celebrities are attracted to it.
Among all kinds of coloured 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 colour is determined by the trace element ‘Cr’, and colour 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’.
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 colour 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 colourimetric stone’ for grading assessment. Its body colour 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.
