As you can guess from the price tag, this is pure, unadulterated 925 Sterling Silver - the highest quality you can get - and so heavy it's got a Silver Hallmark as well as the 925 Silver Stamp! Big, bold and very beautiful, this is the female equivalent of a dog tag, but Tiffany-heart-shaped. Wear it plain - or get it engraved with something meaningful - or maybe a Japanese symbol. Either way, it's just plain and simple drop-dead-gorgeous. Something you'll absolutely adore and wear every day! On a 46cm (18") Sterling Silver Ball Chain. Size: 4cm (1½") x 3.4cm (1¼")
