Hi There,
Although the photos are not so good, much closer would be better, the pearls do indeed look to me like what he sez they are. But for example it is very difficult to see the quality of even the largest abalone pearls by the photo. What the other side looks like is very important. Also the light colored one--not sure what that is about. Have only seen one other cluster of oyster pearls like that one--it had been made into a pendant. You could request some more detailed and closer photos, and see if you can find out just how he got the pearls. Not sure how much he expects to get--sometimes the seller will list the reserve price in the details. Keep us posted, please, and if you are truly interested, the seller should put up some better photos, or at least email you some.
