Vintage Mexico Cantera Opal Sterling Silver Statement Ring

This eye-catching vintage ring is a classic piece of Mexican Silver jewelry, likely dating from the 1960s or 1970s, a period known for large, ornate statement rings exported from regions like Taxco. The centerpiece is a natural Cantera Opal, a unique type of opal mined in Mexico that remains encased in its host rock (rhyolite matrix). The opal itself displays a soft, shifting internal fire, primarily in cool-toned blue and purple flashes, with the matrix providing a natural, earthy frame. The setting features a highly decorative filigree-style bezel that gives the large face a delicate, lacy appearance. This is an authentic piece of vintage Mexican craftsmanship.

The ring is marked STERLING MEXICO. It is a size 6.5 and the face measures 1 1/8 inches long by 7/8 inch wide.
