This bracelet is a nice thick silver with semi precious rectangular and square stone in a patterned bezel setting. Not positive, but believe the stones are Turquoise, Lapis, Gaspeite, Agate and possibly spiny oyster and conch shell. This 925 sterling Taxco Mexico silver cuff bracelet showcases a mosaic inlay motif, with inlay of a variety of stones, and the silver work has been punctuated by a niello darkened finish! Bracelet is simply gorgeous with the vibrant stones set in a blackened niello background to give a kind of depth to the mosaic feel to the cuff. The item was photographed in natural light and accurately reflects the color of the item. Minor variations in color perception may be due to differences between various computer and phone displays
