Cursive letters and one small heart.
Choose one initial or two, and they flow along the chain in a soft handwritten script with a tiny stone set heart beside them. It sits low inside a sweater's neckline in October and out in the open on a strappy top in June. Up close it reads like a signature you would recognize anywhere.
Two initials for the two people who share your last name. One initial when the story is just about you.
