8 Carat Sapphire Engagement Ring in Platinum Yellow Gold.  This spectacular 8 carat sapphire is prong set in yellow gold with the rest of the ring finished in platinum. The stone makes a statement for more reasons that just its size. The sapphire is emerald cut and is set in 18 karat yellow gold, contrasting the diamonds and platinum around it. Being prong set allows for more light to bounce through the stone from all angles, bringing out more of the gorgeous deep blue. Sitting on the shoulders are two trilliant cut .37 carat diamonds whose outside edges seem to flow seamlessly from the corners of the emerald cut sapphire. The clean modern design of this ring allows the sapphire to take center stage while subtle elements like the metal contrast and the angles of the accent stones speak to the skilled craftsmanship involved in this rings creation.
