Chairman's Notes

Burmese sapphires are among the most desirable gemstones, celebrated for their rich blue colour. Some of the finest stones exhibit a rare phenomenon known as "silk" that gives them velvety appearance. With majority of stones unearthed from Burma (Myanmar) are rubies, with fewer than 10% of the gemstones being sapphires, making them extremely rare and among the most coveted sapphires in the world.
