This classic two tone ring has been crafted by our master jewelers from the finest 925 solid Sterling Silver. They have then added another dimension of luxury by setting 21 of our triple Diamondeau? - flawless simulated diamonds in bands of 3 around the ring. These flawless gems rate so highly on the Moh's scale of hardness that they can even cut glass like a mined Diamond and are harder than Emeralds. Magnificent presentation case.
