Not enough necklace length options
Color: 2-Rose Gold-01
The pendant was as advertised. The necklace was not long enough for my wife’s preference and I ordered the longest one offered. I had to use a different company to find the length she prefers. This was her birthday present. Had to spend another $150 just to find a chain. Try offering longer chains.

This bracelet exceeded my expectations
- it's gorgeous! My niece fell in love with it, and I'm impressed that it's resistant to tarnishing. Every penny was well spent.
