Sterling Silver Queen\'s Jubilee Hallmark Polished Heart Pendant Necklace, P3636_JFH As anyone with a love of fine jewellery and its craftmanship will know, the UK hallmark provides a unique and identifying feature to any design. Dating back to the 15th century, UK hallmarking has provided customers with a sign of excellence, origin and approval on all jewellery passed through their Assay Offices for inspection. In a very special year for hallmarking, with the British Hallmarking Council sanctioning a commemorative component mark to celebrate Her Majesty the Queen’s Platinum Jubilee, C W Sellors celebrate these special marks in their new ‘Hallmark Collection’. Across a range of collectable Rings, Necklaces, pendants, and a newly commissioned Heart design, the hallmarks are brought to the fore to wonderfully showcase the quality of the piece chosen worn. Providing a unique and collectable addition to any jewellery collection, each piece carries the official assay marks of the year it was manufactured - 2022 (X), the makers/sponsors mark – C W Sellors (CWS), the metal standard – 9ct Gold (375) or Sterling Silver (925 & Lion), the Assay Office – Birmingham (Anchor) and the new Platinum Jubilee Mark (Orb).Necklace can be worn at different lengths between 16 to 18 inches.
