Round on the outside and flat on the inside, the hoop of this ring widens at the shoulders as it forms the bezel, which is inset with a sardonyx gem (white on brown) engraved with an image of Fortuna.

During the Republic, Romans shunned the opulent display of jewellery. Years later, as the Empire was established, vast amounts of gold and a wide array of luxury items poured into Rome from Greece, Asia Minor, and Egypt. Taste now changed, and it became fashionable to wear sumptuous jewellery. At first, the citizens of Imperial Rome preferred jewellery that exhibited very fine workmanship. But by the 2nd century AD, they favoured eye-catching ornaments made from thin sheet gold, and richly embellished with coloured stones and polychrome glass-paste settings.
