Schlumberger design that was made by Andre Rapicault for the wife of Farnham Lefferts who was President of Tiffany in the 60’s and 70’s.
Yellow and white diamonds frame one of the first Tanzanites to come out of the mines after Tiffany took them over and named the stone. A bright, vivid hue of purple/blue that is not found in today’s Tanzanites, this ring represents extraordinary, iconic design, pedigree and quality. Ca. 1970’s. Size 5 3/4 , 10.69 grams.
