1950s Vintage Ruby and Diamond White Gold Trilogy Ring
Located in Jesmond, Newcastle Upon Tyne
A fine and impressive vintage 0.56 carat ruby and 0.25 carat diamond, 18 karat white gold multi strand trilogy/three stone ring; part of our vintage jewellery and estate jewelry collections. This fine and impressive vintage trilogy ring has been crafted in 18k white gold. The multi-stranded setting displays a central eight-claw set 0.56ct round cut ruby. The ruby is flanked to either side by a claw set transitional modern brilliant round cut diamond, totalling 0.25ct. The stranded ring shoulders conjoin with the feature setting and amalgamate to a plain shank. This 1950s ruby and diamond trilogy ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18k gold. This vintage dress ring is supplied with an IDGL diamond and gemstone grading report card. Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone. Condition This impressive vintage engagement ring is excellent quality, set with an impressive ruby displaying fine colour and brilliance; there is a slight loss to the ruby under one of the claws, this does not detract from the aesthetically pleasing appearance and the ring has been priced accordingly. The ring is an excellent gauge of gold and is in excellent condition. Reflections in photographs may detract from the true representation of this fine small ruby trilogy...
