The PROJECT: This poison ring for this particular 4 carat radiant cut diamond (VVS1). 22 karat yellow gold. Matte finish ( the diamond will *pop* more ) "Make it heavy". Two years later, the ring feels even more important, with gravitas to spare, character weathering into the metal, the snap as crisp as ever. They don't make them like this anymore.....oh wait....yes, we do. Road and cocktail tested, this ring says it for you. Available in 18 and 22 karat gold.
