11.12ct Diamond and 18ct Yellow Gold, Platinum Set Necklace - Antique French Circa 1880


This stunning, fine and impressive statement diamond necklace has been crafted in 18ct and 14ct yellow gold, with platinum and silver settings.

The central 14ct yellow gold, platinum set feature portion of the necklace is ornamented with a central 1.12ct Old European round cut diamond, flanked on either side by a slightly smaller 0.80ct and 0.85ct Old European round cut diamond.

A further eighteen individually claw set Old European round cut diamonds, graduated in size, are set to either side of the feature diamonds.

The feature diamonds setting secures with an integrated push fit clasp to the reverse of a a fully articulated 18ct gold, silver set line style chain, composed of fifty-four square links, each accented with a pavé set Dutch cut diamonds.

This versatile antique French necklace may also be worn as a bracelet, by removing the articulated line link chain via push fit fastenings and substituting it with a circular double push fit clasp.

The push fit clasp is set with a further six pavé set Dutch cut diamonds.

The line style necklace is hallmarked to the tongues of the push fit clasps with the French hallmarks for 18ct gold (eagle's head).

The feature diamond portion and line style settings have been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 14ct yellow gold, platinum and silver.

This versatile necklace/bracelet is supplied with three for the feature diamonds in addition to an independent diamond grading report card for the supporting stones.
