A square-form halo pendant featuring a central claw-set cushion-cut yellow stone, possibly a fancy yellow diamond, surrounded by a border of small round brilliant-cut white diamonds. The pendant is constructed from 18 carat white gold and is suspended from a sterling silver fine trace link chain. The chain is fitted with a carabiner style clasp. The reverse of the pendant bears full UK hallmarks including the maker’s mark RJW, the Common Control Mark scales symbol, 750 (indicating 18 carat gold), a leopard’s head for the London Assay Office, and a date letter. The jump rings on the chain are stamped 925 for sterling silver.
