This necklace is very pretty. It's mostly onyx, so it's interesting that freshwater pearl gets first billing. However, there are a two things with this product that make me give it 3 stars:

1) The beads are not individually knotted. This means that if the necklace were to break, beads would go everywhere and, given the number, would likely be difficult to locate all of them. At some point, every necklace on a string needs to be restrung, since the string breaks down over time with body fluids, exposure to various chemicals, and especially withe motion. Endless necklaces, which tend to be wound multiple times around the neck or knotted into a pattern, experience a lot more stress and wear/tear than a standard 16-20" necklace. Even if worn at the full 30" length, there is a greater potential of getting the necklace caught on something. This all means that endless necklaces are more likely to break.

2) The beads are tightly strung and give the necklace an uneven appearance. Even zooming in on the picture, you can see that there are beads that are not lying uniformly. From a distance, the necklace definitely looks better than close-up.

However, the current price ~$44 may make it worth it regardless, as it can be difficult to find even quality costume jewelry for that.
