Wonderful 18 carat gold ruby and diamond ring.
Modelled as a snake, his tail twisting around his neck in a loop, his head set with a very pretty pear shaped ruby. 
His eyes are little gold balls, and his head and neck are cleverly marked with tiny indents to form scales.
He holds in his open smiling mouth a rose cut diamond set in silver with a gold back.
