18k gold signet ring with onyx - 1970s

Antique signet ring for men fashioned in 18 karat gold. The large rib-like shank holds an oval natural onyx, characterized by an intense black. The chromatic contrast between the brightness of the gold and the darkness of the gemstone makes this jewel particularly refined. It has been perfectly preserved.

Ho fatto pulire e controllare i miei gioielli, quando li ho rivisti ho fatto un salto indietro nel tempo di molti anni, oggi rivedo finalmente questi monili di nuovo brillanti e luminosi come quando mia madre li acquistò da giovane per indossarli e viverli in ogni buona occasione. Non so proprio cosa dirle se non un grazie di cuore. Grazie anche per le riparazioni eseguite a perfetta regola d'arte.
