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. With the ever increasing price of gold we feel it is important that you know exactly what you are buying, therefore we have elected to publish the grams of gold. Your name necklace will not weigh less than what we publish, this is the minimum it will weight in 99.9% of the cases it will weigh more than what we publish. 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.
