A stunning Art Deco platinum ring featuring an antique cushion cut 9.03-carat Ceylon sapphire flanked on either side by three baguette diamonds arranged in a stepped pattern. The sapphire is graded on the GIA scale as vB5/4 (medium tone, moderate-strong saturation, violetish blue color), with eye-clean clarity and excellent cut. The stone's internal characteristics suggest Ceylon as the most likely origin. The overall look is a lovely cornflower blue with a tinge of violet mixed in. The stone is brilliant and easily stands up to the side diamonds, graded as F/VS1. The shank is stamped with French hallmarks for platinum and for 18K (the prongs holding the sapphire are 18K white gold). The interior of the shank is stamped with a serial number and a maker's signature that is now obscured. A stone of this size and quality, complete with a serial number, would suggest a major Parisian house as the maker.
