Understanding Sapphire Prices

Sapphires are the second most popular colored gemstone after rubies, and blue sapphires have been associated with royalty for centuries. The most famous sapphire in the world is the engagement ring of Princess Diana, now worn by Catherine, Princess of Wales -- a 12-carat oval Ceylon blue sapphire surrounded by diamonds.

Kashmir sapphires from the Himalayan mountains of India are the most prized, known for their velvety "cornflower blue" color caused by microscopic silk inclusions that scatter light. The Kashmir mines have been largely exhausted since the early 1900s, making authenticated Kashmir sapphires extremely rare and valuable -- often selling for $20,000-$100,000+ per carat at auction.

Ceylon (Sri Lanka) has been the world's premier sapphire source for over 2,000 years. Ceylon sapphires are known for their bright, lively blue color with excellent brilliance. Burma produces deeply saturated "royal blue" sapphires that rival Kashmir stones. Madagascar has emerged as a significant source since the late 1990s, producing fine blue sapphires at more accessible price points.
