Ceylon Blue Extraordinaire - Vintage Platinum Sapphire & Diamond Ring. This magnificent ring is crafted from platinum, hallmarked Pt 900 for platinum.  Featuring a natural oval fancy cut (no heat treated) sapphire, 4 natural tapered baguettes, 18 natural round brilliant cut diamonds, Art Deco Revival styling and quality custom workmanship. The expertly claw-set sapphire takes centre stage in this ring, displaying a beautiful Ceylon cornflower blue colour, with a violet hue.  The sapphire is enhanced by bright, white sparkling diamonds. The gallery on this ring is exquisite and finely crafted. There are two levels to this ring, the first is set with the incredible sapphire and the second houses the diamonds which enhance the sapphire beautifully. The setting of the sapphire starts with a protective platinum bezel and claws, this allows the true beauty of the sapphire to show.  The shoulders  display a lovely split detail, leading down to a substantial smooth and polished shank.  This Vintage Art Deco Revival piece would make a very unique engagement, anniversary ring, or wonderful addition to any fine jewelry collection.

Note: Appraisal included with this ring.  Gem Identification Report included from Japan.  It is not that often that pieces come with such an elaborate report. The report alone is valued at $500.
