| Overview: Stylish vintage invisible set ruby & diamond ring (circa 1980s to 1990s) crafted in 18 karat yellow gold.
Round brilliant cut diamonds total an estimated 0.50 carats (estimated at G-H color and VS1-2 clarity). The rubies total an estimated 2.25 carats. The rubies are in excellent condition and free of cracks or chips.
The invisible setting is a complex technique of cutting gemstones to fit very close together. This allows the gem setter to cover the surface of the mount with a floating gemstone mosaic look, resulting in a dramatic and unique piece of jewelry. Patented by Van Cleef & Arpels in 1933 and known as the 'Mystery Setting', the resulting jewels from the famed French jewelry house are some of the most memorable jewels ever created.
The statement flower ring is beautifully crafted with the rich red rubies adding a nice pop of color on the hand. Diamonds add shimmer to the outer petals and center set cluster. The medium rise ring (7.5mm - 0.29 inches) sits comfortably on the finger.
The ring is in very good condition and was recently professionally cleaned and polished. Specifications:
