This is a lovely pair of vintage Mexican sterling silver screwback earrings by Sigi Pineda, one of the top Taxco silversmiths. Dating to the 1950s they are early Sigi Pineda earrings with classic Modernist boomerang shapes in 1″ dangles, each suspended beneath a single prong-set stone.
The stones are just lovely, shifting in colour from a violet to a soft blue-indigo-teal colour, impossible to capture in pictures. The violet intensifies and takes over in incandescent/artificial light but is not generally as purple as in the pictures. In natural light, the unusual blue colour is dominant. The stones are 1/4″ (6 mm) in diameter. So far as I’m aware, Sigi used genuine semi-precious stones but I’m not able to identify or guarantee these.
Including the stones the earrings are 1.5″ (3.6 cm) long. One is marked “281” and “STERLING MADE IN ME[xico]“. The other has the early Sigi maker’s mark of “Sigi” above “TAS[co]” in one oval (just the top of the oval has impressed). Above this is the edge of another mark, most likely a mis-stamped eagle assay mark.
The earrings are in good to very good vintage condition – in need of a clean with some age-consistent surface scratching but no damage. The screwbacks are in good working order.
