by Madonna

Rubies, with their striking red hue and enduring allure, have captured the human imagination for centuries. These captivating gemstones have been revered by royalty, adorned by the elite, and cherished as symbols of love and passion. But where exactly do rubies come from? In this article, we will embark on a journey to explore the geographical origins of rubies, delving into the most prominent sources of these precious gemstones.

Introduction To Rubies

Rubies, often referred to as the “King of Gemstones,” are one of the four precious gemstones, alongside sapphires, emeralds, and diamonds. Their rich red color, known as “pigeon’s blood red” in the gemstone world, has made them highly sought after by gem collectors, jewelry enthusiasts, and the jewelry industry. While rubies are found in various locations across the globe, there are a few notable regions renowned for producing some of the finest specimens. Let’s uncover the geological and geographical aspects of these exceptional gemstones.


1. Myanmar (Burma) – The Historical Heart of Rubies

Myanmar, formerly known as Burma, holds a prominent place in the history of rubies. For centuries, this Southeast Asian nation has been a significant source of the world’s finest rubies. The Mogok Valley, in particular, has been synonymous with top-quality rubies. The rubies from this region are celebrated for their intense red color, often displaying a hint of blue, and are considered some of the most valuable.


The geological processes that have led to the formation of these precious gemstones in Myanmar are rooted in the collision between the Indian Plate and the Eurasian Plate. This tectonic activity, which occurred millions of years ago, created the ideal conditions for the formation of rubies. The ruby deposits in Myanmar are found in marble, and miners must extract them from deep within the Earth, making the process both challenging and labor-intensive.


The legendary “Valley of Rubies” has been the source of world-famous rubies, including the Sunrise Ruby, which holds the record as the most expensive ruby ever sold at auction. The history and significance of Myanmar as a ruby-producing region continue to draw attention and fascination from gemstone enthusiasts and collectors worldwide.

2. Thailand – A Hub for Ruby Trading

Thailand has played a pivotal role in the global ruby market, particularly as a trading and processing hub. While not as well-known for ruby mining as Myanmar, Thailand is renowned for its expertise in cutting, heat-treating, and enhancing rubies’ color. Rubies from various sources, including Myanmar, Mozambique, and Tanzania, are often sent to Thailand for processing and polishing.

The Thai city of Chanthaburi, known as the “City of Gems,” is a major center for the ruby trade. Here, gem dealers, cutters, and jewelry designers converge to trade, cut, and create exquisite ruby jewelry. Thailand’s skilled artisans are revered for their craftsmanship in enhancing the color and overall quality of rubies. Through heat treatment and other techniques, they can improve the appearance of rubies and make them more marketable.

Thailand’s significance in the global ruby industry extends beyond trading and processing. It serves as a bridge connecting the world to the finest rubies from Myanmar and other regions, making it a pivotal player in the ruby supply chain.

3. Mozambique – A Rising Star in Ruby Production

Mozambique, a country in southeastern Africa, has emerged as a significant ruby-producing region in recent years. Its ruby deposits, particularly in the Montepuez region, have garnered international attention for their exceptional quality. Mozambican rubies are typically sought after for their deep red color and transparency.

The geological processes that have given rise to Mozambique’s ruby deposits are tied to the region’s ancient metamorphic and igneous rocks. These geological conditions have created the perfect environment for the formation of rubies, making Mozambique one of the world’s most promising sources of these gemstones.

Mozambique’s ruby boom began in the early 2000s when a significant ruby deposit was discovered in the Montepuez region. This discovery led to a surge in ruby mining operations, attracting miners, investors, and gem enthusiasts alike. The region’s rubies have become highly regarded for their color and quality.

4. Madagascar – A Treasure Trove of Rubies

The island nation of Madagascar, located off the eastern coast of Africa, has also gained recognition as a valuable source of rubies. Madagascar’s ruby deposits are spread across various regions, with some of the most well-known deposits located in the Andilamena and Vatomandry areas. The rubies from Madagascar are known for their appealing pinkish-red and purplish-red colors.

Geologically, Madagascar’s rubies are associated with rocks of the island’s Precambrian basement complex, which have undergone intense geological processes over millions of years. These processes have given rise to the ruby-bearing veins that are mined for their precious gemstones.

Madagascar’s rubies have made their mark in the global market, appealing to both collectors and jewelry designers. The unique colors of these rubies make them distinct from those found in other regions, and they have been used to create captivating and unique jewelry pieces.

5. Tanzania – A Notable Ruby Source in East Africa

Tanzania, another East African nation, has also joined the ranks of countries producing rubies. The ruby deposits in Tanzania are primarily found in the Mtwara region, in the southern part of the country. Tanzanian rubies are recognized for their vibrant red color and are typically characterized by their clarity.

The geological history of ruby formation in Tanzania is linked to the same tectonic processes that have shaped much of East Africa. These processes have created suitable conditions for the formation of rubies, often associated with marble and metasomatic deposits.

Tanzania’s ruby industry is relatively young compared to some of the established ruby-producing regions, but it has shown promise and potential. As the country continues to develop its mining operations, Tanzanian rubies are gaining recognition in the international market.

6. Other Ruby Sources – A Global Perspective

In addition to the aforementioned regions, rubies can be found in various other locations around the world. These sources may not be as prominent, but they still contribute to the global supply of rubies. Some notable locations include Afghanistan, Cambodia, Sri Lanka, and Vietnam.

Afghanistan has a rich history of ruby mining, with deposits found in the Jegdalek and Sar-e Sang regions. The rubies from Afghanistan are known for their deep red and pinkish-red hues.

Cambodia is famous for its ruby deposits in the Pailin region. Cambodian rubies are known for their intense red color and are often referred to as “Burmese-type” rubies due to their similarities with Myanmar’s rubies.

Sri Lanka, long known for its sapphires, also has ruby deposits. Sri Lankan rubies are typically lighter in color, with pinkish and purplish tones.

Vietnam’s Luc Yen and Quy Chau regions have also produced rubies, known for their deep red color.
