2ct Diamond and Platinum Trilogy Ring - Antique Circa 1920


This fine and impressive 2 carat trilogy ring has been crafted in platinum.

The pierced decorated, multi-claw basket setting displays a central 0.78ct Old European round cut diamond.

The central diamond is flanked on either side by a slightly smaller 0.60ct and 0.62ct Old European round cut diamond, completing the trilogy arrangement.

The pierced decorated, elevated and tapering ring shoulders integrate with the main setting and blend seamlessly with the plain hallmarked ring shank.

The ring is hallmarked to the interior of the shank with the maker's mark 'S.B.S LD' and the mark for platinum (PLAT).

This impressive antique three stone ring is supplied with three independent diamond grading certificates.
