On a recent trip to China my wife bought for a sizable sum a large black pearl (14mm) at an upscale jewelry store in a very modern mall (a store that should be reputable dealer). Unfortunately, after we got home she dropped it on a tile floor and it broke into two pieces. The inside is not at all like the outside and my wife now thinks she was sold a fake. I am not convinced either way. The inside does not look like what I would expect the inside of a pearl look, but I have never seen the inside of a pearl. It seems to me that the inside may be consistent with a cultured pearl. I am attaching pictures of the broken pearl and hope you may be able to tell from looking at them whether this is a true pearl (cultured or otherwise) or a fake. If it is a true pearl, would anyone be able to venture an approximate price before it was broken. Thanks.
