Color Award: Pigeon Blood Red
Color Award Description: Macabre, as it sounds, "Pigeon Blood Red" refers to a color category reserved for the finest, high-caliber rubies that exhibit a vibrant and vivid crimson red color. The term is said to have originated in Burma, where locals call the most vivid rubies "ko-twe", meaning "pigeon's blood". It is said that a perfect ruby is the same color as the first two drops of blood from the nose of a freshly-killed pigeon.
Pigeon blood red is the most sought-after color in rubies, surpassed by no other. While these rubies are usually devoid of purplish/pinkish/orangish/brownish overtones, some stones may show a slight purple hue.
While Burma (Myanmar) - particularly the Mogok region - has historically produced the most legendary pigeon blood red rubies, the nomenclature is not exclusive to the country. Other localities that yield fine-quality pigeon blood red rubies include Mozambique, Madagascar, Tanzania, Tajikistan, Afghanistan, and Vietnam.

Gemologist's Comments on Clarity:
Due to their natural growth conditions and recovery methods, rubies from Burma (Myanmar) commonly have features such as growth tubes, fingerprint inclusions, rutile silk clouds, and other microscopic inclusions that may affect the transmission of light to a certain extent. For this reason, despite being fully transparent, Burmese rubies may not show luster & scintillation as prominently as rubies from other localities.
