The "Silk Road" of ancient China was originally used to transport silk produced in ancient China. It was also the main road for cultural, economic and political exchanges between China and European countries at that time. The gems of various countries are also transported to Europe and China by means of the "Silk Road". But at the end of the Middle Ages, wars and plagues hampered the development of the Silk Road, and trade transport also shifted from land transport to maritime transport along the Indian Ocean.
As a result of this transformation, the gems produced in countries along the Indian Ocean have become more and more transported and traded. Since then, Myanmar has gradually become the world's leading source of rubies, and it has been centuries old.
For more than 30 years after 1962, the border areas of Thailand and Cambodia have also become the main producing areas of rubies, and Thailand has become the main trading center of ruby ​​because of its origin and heat treatment technology. In 1992, the production of rubies in the border areas of Thailand and Cambodia began to decline. In the following 20 years, rubies from Mengcun in Myanmar caught up and became the protagonist of the market. This is also due to the improvement and application of heat treatment methods in Thailand.
In 2004, a new treatment method, high-lead glass filled with ruby, was introduced. This new heat treatment method allowed the quality of the ruby ​​from East Africa to be processed on the market. Despite the controversy over the durability of lead glass filled rubies, it is undeniable that Madagascar, Tanzania and Mozambique have become important producers of rubies.
Ruby (except lead glass filled with ruby) is very durable, and some precious rubies can be preserved even after several centuries.
The rubies that are common on the market today come mainly from three types of mines. The classic marble-type ruby ​​mines are in Mogok, Myanmar, the basalt-related ruby ​​mines such as the border between Thailand and Cambodia, and the new amphibole-related ruby ​​mines such as Mozambique. Although the red color of ruby ​​is caused by chrome, the difference of iron makes each jewel of different origins attractive.
Now, the gemstone production report is getting more and more attention in the jewelry trade. Although each mine has the potential to produce high-quality gemstones, some are known for producing high-quality gemstones. For example, the prestigious Myanmar. As the oldest ruby ​​producing area in the world, Myanmar has discovered many large-grain, high-quality rubies for centuries. Its importance is unmatched. Because of this, “Myanmar†is also known as the “hometown of rubiesâ€, and rubies from this historic mining area also have higher market value. This is also reflected in the recent auction, the price of high-quality rubies broke records once and for all, and they all came from Myanmar.
