If you wish to look at necklaces which are personalized, you would want to opt for those which have initials on them. Some come with chains and pendants that have initials as pendants. Another option is engraved necklaces that have the initials engraved on the necklace.
Decide On What You Want
For engraved necklaces, you need to have an idea of what you want. Getting a customized necklace might be expensive but you would get the design you are looking for. Engravings of initials or of a special sign or symbol that has meaning for you will make such a necklace a worthy treasure for a lifetime.
Accordingly, you could decide on the material you wish to opt for. Customizing engravings on a gold necklace is possible but might not be easily done on sterling silver or tungsten. If you are looking for initials, these are easily found on fashion jewelry as well as seen below.
