Roselane Antiques has dated this piece to the 1950s.
The briolette cut continues and covers the complete underside of the stone. This gives a special effect looking down on the topside of the ring with the gemstone catching the light from every angle.

The Aquamarine is encased in a smooth finished platinum surround. The millegrain detail adds that finishing touch drawing the eye to this stunning ring.
Although the Aquamarine is 9+ct the diamonds that surround it are not overshadowed. The bright and lively diamonds also edged in millegrain beading complement the central stone perfectly.
Aquamarine approx: 9.5ct.
Diamonds approx: 1.50ct.
Clarity approx: VS-VS1
