An Art Deco Lavender hued Natural Star Sapphire & Diamond Ring
This pretty stone is set in a Platinum Ring Mount with twenty six small round Diamonds and six Baguette Diamonds.
The inner shank marked Platinum and faintly engraved MHL to MGZ, my guess is that this was given as an Engagement Ring in the 1920's.
Finger size: 6 USA L 1/2 UK 12 Japan
