What Is The Difference Between Mozambique And Burmese Ruby?
Most rubies are mined in Southeast Asia, Australia, Brazil, and India. Over the years, the majority of rubies have been discovered in Myanmar's Mogok Valley.

Mozambique Ruby
Mozambique produces the majority of the rubies used in joaillerie and high joaillerie. This is especially true for stones weighing two carats or more; for the time being, Myanmar is the leading producer of rubies in small sizes. Until recently, Mozambique's ruby production was very traditional. However, towards the end of 2012, the government wanted to solve this by granting a mining corporation a concession over the Namanhumbir deposit in the country's northeast. This extremely prospective deposit spans over 30,000 hectares. When nature is kind, we get highly crystalline rubies that are deep red and slightly orangey.
Mozambican rubies are typically purplish red to red in color, with some stones exhibiting an orange tint. The color intensity ranges from delicate pink sapphires to bright red rubies. Gem corundum has the following standard gemological properties: a refractive index between 1.760 and 1.768 (+/– 0.001), birefringence of 0.008–0.009, and a specific gravity average of 3.98–4.00. Fluorescence can range from strong to medium red in long-wave UV radiation and from medium to faint red in short-wave UV radiation.
Particles are the most prevalent type of inclusion. These oriented needles and particles frequently form in bands that follow the corundum development structure. Maninge Nice–type rubies frequently have these entire hexagonal shapes. Mugloto-type rubies rarely have a whole hexagonal outline, but instead feature straight or angular bands of particles.
The inclusions in both varieties of Mozambican ruby are the identical, although their quantity differs. Mugloto rubies have fewer mineral crystals than Maninge Nice rubies. Maninge Nice rubies exhibit more cracks, which can be attributed to their position in a primary or near-primary deposit.

The market value of a ruby is determined by various characteristics, including its size, color, purity, and size (its "cut"). All natural rubies contain inclusions; only synthetic rubies can give the appearance of being flawless. The rarer and more tiny the inclusions, the more expensive the stone. It is the precious stone that can acquire the highest values, along with colored diamonds.

Burmese Ruby
Burmese rubies are the rarest gemstone in the world due to their intense red brilliance accentuated by pink. The majority of the rubies mined in Burma are then heated to improve color and clarity. Natural color specimens that are inherently pure and bright are extremely rare. The majority of rubies produced in Burma are subsequently heated to increase color and purity. The most intense color is known as "Pigeon Blood." This is a precise shade of red with a tinge of blue.
Burma is the world's leading producer of rubies, accounting for 90 percent of global output. The remaining production is split between Thailand, Madagascar, Sri Lanka, Kenya, and Tanzania. Because some places are far more popular than others, the provenance of the stone is an important consideration in determining the price of a ruby. The most popular are those from Burma, which are distinguished by their brilliant color, silky smoothness, and extremely strong fluorescence. The Ceylon region of Sri Lanka is also known for its outstanding brilliance and purity of rubies.
Burma has closed in on itself since the military government took power in 1962, making access to manufacturing areas nearly impossible. As a result, the vast majority of Burmese rubies are handled locally by Thai traders before being transported to Bangkok to be sold.

The major criteria for judging ruby are color and intensity. Its hue has a broad spectrum that ranges from pinkish red to brownish red. The most stunning specimens have a translucent red tinge that allows light to pass through. The most sought-after and scarce color is certainly "pigeon's blood," a vivid red with a hint of blue. Rubies frequently have a secondary color. Burmese rubies, for example, are red with purple undertones. It should be noted, however, that the more obvious the secondary hues of the ruby (purple, orange), the lower the value of the ruby.

With over ten years of marketing experience, I finally decided to settle down in Bangkok to work in an area that I have always been interested in: the gemstones industry. I'm still learning how the market works on a daily basis, and I enjoy sharing my experience with those who are interested in learning more about gems in general.
