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.
