Native American Made Sterling Silver & Opal Slide Conchos

Here is an absolutely stunning concho set! All vintage, clearly Native American made in a classic, oval shape with scalloped edges and intricate engraving. Each have a large center stone in what appears to be natural pink opal that offer a stunning, iridescent pale pink and pearl color. Comes a 6 piece set, each measuring 1 1/16″ x 3/4″ with a brass loop back mounted on the back. Will fit a leather piece/belt/strap up to 5/8″ in diameter. Not marked with a makers mark, but each are marked sterling. While vintage, clearly these have been very well cared for and are in excellent condition. Do show natural patina. Lovely set, these would be stunning on a hat band or belt!
