Beautiful blue sapphires have been unearthed for over 1000 years in the old Burmese mines, and are a rare occurrence amongst a sea of rubies. Highly coveted for their rich blue hue, the exceptional qualities of these sapphires have led to them becoming one of nature’s most sought after, yet elusive gems. While the majority of gemstones mined in Burma are rubies, equally sought-after by connoisseurs are Burmese sapphires, which account for fewer than 10% of all material discovered in this area.

This geological origin combined with their unenhanced characteristics makes pieces like this highly sought after for collectors of fine quality rare sapphires.
