This fine and impressive antique pendant has been crafted in 18 ct yellow gold with a platinum setting.

The pendant displays a central four claw set 1.80 ct cabochon pear cut opal, which suspends and articulates via a platinum set paired leaf design incorporating two pavé set Dutch cut diamonds.

This suspended design is bordered by an oval shaped wreath decorated setting embellished with Dutch cut diamonds, displayed within the foliate ornamentation.

The pendant suspends from a contemporary 18 ct white gold trace chain via an integrated ring loop to the upper border of the design, and secures with a conventional spring-loaded bolt ring fastening.

The tapering elongated bale is accented with three pavé set Dutch cut diamonds.

The reverse of the bale is hallmarked with the 18ct gold fineness mark (750) and the chain features the makers mark, the common gold guarantee mark (750 scales), the 18ct gold fineness mark (750) and the Birmingham Assay Office hallmark (anchor).

This impressive antique opal pendant with diamonds has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as 18 carat gold and platinum.
