Pigeon's Blood
The term comes most appropriately from Burma, home to what are considered to be the finest ruby specimens on earth and where local miners have, for generations, compared the most vivid red examples to the first drops of blood from a freshly-killed pigeon.

This vernacular description was picked up by the trade, who also reserve it for the very best-in-class coloured rubies and it subsequently appeared on a laboratory certificate for the first time in 1996. Since this date, it has been adopted by most major international laboratories. Being attributed the fabled "pigeon's blood" suffix by a laboratory confers on an unheated Mogok ruby the highest pedigree and makes it significantly more desirable in the market.
