The initial measures approximately 0.7cm/0.27" top to bottom and comes with a 16" sterling silver chain. The necklace also comes with a matching pouch (5.5cms x 6cms / 2"x2.3") and black ribbon tie that I made from complete scratch out of 100% white cotton twill fabric. The seams are overlocked and I printed the initial to compliment the necklace, perfect as a gift! Note: The initial does not have any stamp to state it is 925 sterling silver, this is because it is so tiny, that any stamp would distort it. The chain is super delicate and in a curb style. It is stamped with 925 on the lobster clasp Model photo is just for scale.
