Set of modernist Mexican earrings bearing the Los Castillo signature, each earring featuring two male profiles, one executed in silver, the second with azur-malachite inlay. Though the Mozaico Azteca technique employed here was among the innovations and revivals the Los Castillo workshop is credited for, I believe the pair at hand was in fact designed by their cousin, Salvador Teran, when he was still working with them. The set's sheer minimalism is only tempered by the saturated color in the stone with each earring showcasing one of the two dominant colors in azur-malachite, blue and green. Measuring 1/2" tall by 11/16" wide;= the earrings weigh 7.5 grams (for the set) and are fully signed with the Los Castillo name as well as "HECHO EN MEXICO", "MOZAICO AZTECA", des. no 259 and Eagle 16 assay mark (badly stamped but present). They date ca 1950 and are in excellent vintage condition with great patina and beautiful color in the inlay which is in very good shape as well, with no damage and no repairs noted.
