The Importance of Ruby Origin: More Than Just Geography

For decades, ruby origins were often overlooked in the buying process—except for stones from legendary sources like Myanmar’s Mogok Valley. Yet, in the last 15 years, consumers and experts alike have grown increasingly aware that a ruby’s geographical origin impacts its appearance and worth.

Each mining location has unique geological conditions that influence the ruby’s chemical composition, crystal structure, and inclusions—all factors that shape its color and clarity.

The Classic Standard: Burmese Rubies from Mogok

For centuries, the Mogok region of Myanmar (formerly Burma) has set the benchmark for ruby excellence. Burmese rubies are treasured for their intense, vibrant red, a slightly purplish or pinkish red with a soft, glowing fluorescence.

This remarkable red color owes to the low iron content in marble-hosted rubies from Mogok, which results in pure, saturated hues and a brilliant luminosity under natural and ultraviolet light.

However, these prized rubies nearly always contain fine “silk” inclusions (needle-like rutile minerals) that scatter light softly—adding to their allure rather than detracting from it. Large, fine Burmese rubies are exceedingly rare, so their value climbs steeply as carat weight grows.

Mozambique Rubies: The Rising Star of Ruby Origins

A newer but equally exciting source is Mozambique, whose ruby deposits were unknown to the wider market before 2008. Since then, Mozambican rubies have surged in popularity due to their vibrant color and remarkable clarity.

Mozambican rubies fall mainly into two types:

• Maninge Nice rubies, known for brilliant color and strong red fluorescence, although often found flat with fractures that are improved by flux healing.

• Mugloto rubies, which are bulkier with fewer fractures but tend to have darker or orangier tones and weaker fluorescence, sometimes enhanced by heat treatment.

While Mozambican rubies may display slightly different hues than Burmese stones—some darker, some with varying red tones—they can rival the finest rubies in beauty and brilliance. They also offer consumers a more accessible price point, making high-quality rubies attainable without compromising on appearance.

Thanks to efforts in ethical mining and formal exports, Mozambique has established itself as the world’s largest source of rubies by volume, with significant production expected to grow in the years ahead.

Other Notable Ruby Origins and Their Influence

Besides Myanmar and Mozambique, rubies are found in several countries including Afghanistan, Sri Lanka, Madagascar, Tanzania, and Vietnam. Each location provides rubies with distinct characteristics due to differences in host rock and trace elements. For example:

• Sri Lankan rubies often exhibit a range of pink to red shades due to higher iron content.

• Basalt-hosted rubies from several locations tend to have darker color tones and less fluorescence than marble-hosted stones.

• Rubies from Vietnam and the Himalayas can rival Mogok rubies in color but are usually less available in larger sizes.
