This Prayer Box Pendant is Made of Solid Sterling Silver and it is antique finished to show details of the design. It measures over 1 1/4 inch tall not including the bale, and inside diameter is about 3 mm smaller than the width. You also have the option to purchase this Prayer Box with a Sterling Silver 2 mm Rolo Chain (at a discount) we think is a good match. But if it turns out that you don't agree, you may return this chain and get the credit for the difference. .
