Knowledge & EducationRubies were thought to ward off misfortune and ill-health. They are given as a symbol of success, devotion and integrity.



The king of gemstones owes its popularity to its intense fiery color and symbolic values. The shades of ruby are countless: they range from pink through blood red to darkest purple. The most highly regarded color is what is known as “pigeon blood” red; a dark, saturated shade of camine red. The more intense the color and vivid the sparkle, the more sought after is the ruby. Another important characteristic to consider when valuating rubies is that the vast majority of rubies come in sizes under 5 carats. Stones over 5 carats are extremely rare and those over 10 carats are an irregularity in nature.

Natural rubies are commonly heat treated to improve the color and brilliance of the stone. Since most rubies have undergone this standard treatment, to find a ruby that is unheated is very rare and therefore they fetch significantly higher prices.


The first discoveries of rubies are only vaguely traceable to the 15th century. Burmese rubies have a long history and represent the finest quality rubies found on the global market, most of which come from the famous Mogok mines, which are also known as “The Valley of the Rubies”. These are the most sought after of rubies due to their scarcity, the best of which come in a vibrant “pigeon’s blood” red color and high luster.


Rubies were first disovered in Thailand during the early 1400s near Chantaburi, in the south east of the country on the border between Thailand and Cambodia. Thai rubies are often known to be darker than their Burmese counterparts, but the finest Thai rubies display an incredibly high level of clarity and brilliance and come in a vivid red color known in the trade as “imperial red”.


In 2008 new ruby deposits were discovered in Mozambique. The finest quality rubies coming from these mines have similar characteristics to those from Burma; they are of a vibrant red color with a fine luster.


Ruby deposits were first discovered in Tanzania around the 1950s. These rubies are often a softer shade of red, usually with a tinge of orange hue. They usually have a very good clarity and a soft luster.

Other Ruby Sources Include: Afghanistan, Cambodia, India, Kenya, Madagascar, Nepal, Pakistan, Sri Lanka, Tajikistan and Vietnam.
