I bought this necklace for an inexpensive gift but am considering keeping it myself.  The luster is not up to the quality of more expensive pearls that I own, but I did not expect it to be.  I did not measure the pearls but they are quite large.  The clasp is not the traditional "pearl clasp" but it is a silver ball with the same type of security feature (a hook that pushes into the ball).  The necklace does not hang smoothly just yet, but the pearls are heavy enough that I expect it to stretch out just a bit, and I am considering adding a pendant to make it hang more smoothly.  The 18" length is comfortable, and would show well if worn with a v-necked blouse.  The necklace arrives in a white imitation leather drawstring pouch.  I am giving it four stars because it is not perfect, but it is worth the price I paid.
