I purchased 2 Tennis Chains, one was a 14k yellow gold 3.5 mm round moissanite and the the other was a 925 Silver 4mm round moissanite chain. Obviously you could tell the difference in the quality and craftsmanship on the 14k Tennis Chain. The 925 Silver chain was also not bad at all. If you have a very hairy neck these chains will pull your hair, if you have a little bit of neck hair you will be fine. Overall my experience with Olivia was great, there company had slightly more expensive jewlery pieces when comparing similar items but Olivia assured me that was because there quality and craftsmanship was superior then the competitors.
