An important sapphire and diamond 3 stone trinity ring with a WOW factor second to none. Worn as an engagement ring or statement cocktail piece, it is hard to miss. Centered by a near 7 carat oval gemstone with an incredible, vivid cobalt blue and flanked by a pair of triangular cut diamond trillions weighing a combined 1.78 carats, they are of an icy-white F color with a fiery brilliance. With a huge amount of finger coverage yet still sitting relatively low on your hand you will enjoy flaunting this vintage heirloom, recently acquired from a San Francisco area estate.
