I am revising this review after having some email conversations with the seller. This product is 18" inches in length, however, just note that due  to the size of the pearl and the fact that it does not drop down, but it on the chain like a bead, it takes up a bit of room and thus, seems to be shorter in length when  you put it on your neck, sort of like a choker. I hope this clears up any misunderstanding. I do like it though and may get the pink pearl as well. Very good quality.

Decided to splurge a bit and buy this as it was advertised as a high quality pearl. It is pretty and I like the sparkly chain, the way it catches the light. However, I do not think the chain is 18" as stated, but 16", so be careful there. Still it fits and dress's up a pair of jeans and t-shirt or whatever you wear.
