Product｜Blue Sapphire・Ceylon Sapphire・Ceylon Sapphire Quality｜<<Unheated>> This sapphire from Ceylon (Sri Lanka) has become a coveted treasure for high-end sapphire lovers with its natural beauty without heating treatment and extremely rare cornflower blue light.

It is a dream product for those who pursue blue sapphires around 1 carat. Quantity: 1.35 carats. Size is large enough for rings, suitable for both men and women.
