A stunning early Victorian ring with a hidden shaped ‘poison’ panel behind the head of the ring. The central pearls are mounted on either side with graduated turquoise cabochons.
 
They are held in silver crimped collet settings and the ring is in very good antique condition.
 
The pearls have a silver white tone with lustre, and the turquoise match well.
A rare example of this type of ring.
