This necklace is a great gift for best friends, sisters, mother, daughter or your significant other. The necklace length is 20 inches. It comes on a card that says "You and Me Forever!" The infinity symbol is 15/16 of an inch long and 3/8 of an inch wide. You can also choose to have birthstone crystals on the necklace. I can do up to 3 crystals. And to have your initials stamped on a tag. I can do just one initial or up to 3 characters. I have a heart tag and a circle tag. Once you've added this listing to your cart there will be a box to leave me notes. Let me know what birthstones you'd like on the necklace and the initials for the tag.
