Translation of "cameo" into Arabic

And my wife's grandmother's ring was in there, her mother's cameo.

وخاتم جدة زوجتى كان هناك ايضاً, و الحجر الكريم الخاص بأمها

Likely during the 16th century, conchs of the Cassidae and Cypraeidae families were found to be particularly suitable for cameo engraving.

ويرجَّح انه خلال القرن الـ ١٦، وُجد ان محار فصيلتَي الخوذيّات والوَدَعيّات يلائم خصوصا نقش الكامِيُو.
