Sarah was great when I accidentally ordered silver as opposed to gold. She was very helpful and the new necklace came back great and was a very easy process.
I love my necklace but it is just not long enough. The extension piece gives it much more versatility. However, I feel it throws the balance of the necklace off. The weight of the pendant is not enough to keep it at full length (I think the extra weight of the extension is the problem) and I frequently (at least once an hour) have to adjust the pendant forwards. I love the necklace though and it doesn't stop me from wearing it
