All of our jewelry bears a hallmark stamp of the government, attesting to the fact that it is 18k gold, 900 silver, or 925 (Sterling Silver). It is not a dent, or a flaw, it is the stamp, this is your protection. Please be advised, dimensions are approximate and are given as a guideline. Actual dimensions will depend on the nature of the letter, the width of an "m" will be different than the width of an "i". All sales are final on name necklaces as each one is a personalized order, a picture will be sent for your approval prior to shipping. Please read our policies.
