Vintage Taxco Mexico 925 Sterling Silver Abalone Shell Ring - Size 7.75

Vintage Mexican sterling silver ring set with an oval abalone shell cabochon, marked with the eagle 3, HECHO EN MEXICO, and 925. The eagle is the Mexican government assay mark, stamped on silver from 1948 until it was retired at the end of the 1970s and replaced by the letter and number registry used today, and the 3 inside it is the number assigned to Taxco. Taxco is the mountain town in Guerrero that became the center of Mexican silversmithing in the twentieth century, and this ring carries the vocabulary that made its work recognizable: a hand pulled twisted rope wire framing the bezel, and applied silver beads arched in graduated rows above and below the stone.

The shell is where this one earns its keep. Abalone nacre throws green, rose, lavender, and silver blue across the dome, and the colors move as the hand moves rather than sitting still the way a dyed or printed shell would. A darker figured patch sits off center with a soft halo ringing it, the natural growth structure of the shell itself, and the curve of the cabochon stretches the color bands around it. The bezel is high and smooth, the rope twist is evenly laid, and the beads are polished bright so the frame reads as light against the dark iridescence. The shank splits into a double band at the shoulders, which keeps the mounting tall and the profile open.

Ring size 7.75. This wears as a statement piece, Southwestern in feel and unmistakably Mexican in construction.

Fun Facts:
Taxco mined silver from the colonial era but had almost no tradition of working it into jewelry until 1931, when American architect William Spratling opened a workshop there and trained local apprentices, seeding the industry that made the town's name.
The color in abalone is not pigment. Nacre is built from stacked plates of aragonite each roughly the thickness of a wavelength of visible light, so light reflecting off successive layers interferes with itself, canceling some colors and reinforcing others, which is why the greens and pinks shift as the angle changes.
