This vintage dark blue sapphire and diamond cocktail ring makes quite a statement on one's hand. The brilliant 18 karat gold really sets off the sparkling diamonds beautifully. The center oval sapphire is surrounded by 36 2.0 mm round brilliant-cut diamonds that are prong-set on two tiers. There are 16 diamonds on the first tier and 20 diamonds on the second tier for approx. 1.08 ctw. The oval sapphire is prong set in 18 karat yellow gold and measures 9 mm x 7 mm x 3.5 mm (approx. 1.75 ct). The band is split in three sections at the shoulder and tapers to a simple 4 mm wide band.
The ring is marked "18K" and has the maker's marks of "KK"" or "HH". It is hard to read. It also bears the stamp of a ship, perhaps another maker's mark.
The face of the ring measures 17 mm x 15 mm. It weighs 7.2 grams and is a size 6 3/4 US. It is in excellent condition.
