DATE: Art Deco, c.1930

If you know sapphires, you'll know that a 7.57 carat no-heat Burma sapphire isn't to be taken lightly... Here, mounted in a superb diamond-studded late Deco signet mount, is an exceptional example of a no-heat Burma sapphire. Clear as glass, with no inclusions visible to the naked eye, it displays an incredible velvety intense blue colour - with certification confirming the origin, size, weight, and lack of treatment. It's set in an oval ring of fine platinum millegrain, with 1.80 carats of transitional cut diamonds pavé set all round, and French control marks confirming the ring is crafted in platinum throughout.
