Here's my latest collection embedded pink and blue enamel kissing characters. It's made of genuine sterling silver in a heart shape with a rose gold flash plated key and has S925 (sterling 925/1000) embedded on the back. The chain is 18" with a 2" extender making a total of 20" in length and a lobster claw clasp, marked S925. The weight of this beauty, pendant and chain, total 3 grams. The measurements of the heart are approximately 15mm in height by 13mm in width. The bale is soldered and secure daily wear, and it's made for the 24/7 wearers. This is a keeper!
