EVER2000Custom Name Necklace, 18K Gold Plated Nameplate Personalized Jewelry Gift for Women

How long of the chain is suitable for 20yr old?

I was wondering if u can put a blue diamond stone into the heart that separate two names pleas

Can you have 2 capital letters, i.e. mrsdoe w/ “M” & “D” in caps? Can you do a hyphen or space, i.e. mrs-doe, mrs_doe, mrs.doe or mrs doe w/cap m & d?

Can I use dashes “/“ in the customization?
