This elegant ring is made from 14kt solid gold. It is set with our Shelby Synthetic Blue Sapphire There is 3.11 carat size of sparkle. We really make all of our Sapphires. They have the same physical, chemical and visual properties as a natural sapphire. Guaranteed! They look better than any but the very best natural sapphire. It's impossible to tell the difference with just your eyes! If you use a microscope, you will see flaws in all but the very best natural sapphires. You will see no flaws in ours!! Very pretty ring!!
