This lovely unheated Ceylon sapphire is a beautiful deep cornflower blue–one of the most desirable hues for a sapphire.  Sri Lanka (formerly called Ceylon) is famous for its gemstones, especially sapphires.  The government has maintained regulation over mining to prevent large-scale environmentally destructive mining from occurring, encouraging small-scale artisanal mining.  This sapphire was acquired directly from a mine owner in Sri Lanka, and then recut here in the United States for maximum beauty and brilliance. The gem is 100 percent natural and untreated in any way.

This sapphire is extremely clean, with just a few tiny inclusions only visible with 10x loupe.  The classic rectangular cushion shape was recut here in the US to increase the brilliance of the gem.  The sapphire weighs 4.29 carats and measures 8.9 x 8.1 x 6.6 mm.  It would make the perfect gem for a unique engagement ring!
