The pure, deeply saturated red of this unheated ruby is intoxicating. One of the most vibrant and vintage gemstone Art Deco engagement rings in our estate jewelry collection and GIA certified, this rare, round ruby from Madagascar is set in a perfect platinum setting. Weighing a bold 1.46 carats, you'll enjoy the contrast of the round gem set in a square frame enhanced by a trio of diamonds on either shoulder along with subtle hand engraving.
