I'm obsessed with this Stella and Dot bar necklace. It comes in gold or silver and can be engraved with either a date, a single initial, two initials, three initials (which you can see is what I chose), or single or both initials with a heart between them! I love that it has a split chain and 2 length options, 16" with an extender, so it could also be 18". I also think it looks great layered or on it's own. And when it comes to personalized jewelry I think Stella and Dot has very reasonable prices!
