I recently received the two hearts pendant for my birthday, but i'm now torn between the two hearts or the double loving heart pendant!! can you guys please help me decide, i've been waiting to wear my very first tiffany necklace
, but have to hold out since i'm stuck on whether or not to exchange it!
Also, do they charge for a longer chain? i got the 16 inch one, but i really like my necklaces to hang a bit lower since i feel like i have a rather thick neck so i'd like to exchange it for the 18 inch one, regardless of which one i decide on.
