Oval Sapphire Diamond Halo Earrings in Platinum.  These modern sapphire and diamond studs have such a sparkling appearance! The earrings feature two (2) 1.25 carat oval cut sapphires wreathed in .24 carats of round brilliant cut diamonds and are set in platinum. The sapphires are set using thick prongs with a high polish that together with the diamonds give plenty of bright sparkle to contrast the deep blue. These would be perfect for a fancy evening out!
