Precisely. It isn't easy to calibrate Xray for pearls. Just asked dentist this morning - he says that his machine is not good enough and doubts that any medical Xray would have sufficient resolution to tell anything aside nucleated vs. non-nucleated. And even then, only if there is separation between nucleus and nacre. This coming from experiments with Akoya. Could be that he couldn't be bothered, but I doubt (great guy )

Wonder what type of parameters/setting is used to analyse pearls Anyone knows?

I can't answer your question Ana, but the GIA has a really interesting xray machine. they brought it to the Gem show here in Tucson last Feb. I got to look at some CFWP that I brought. It like a big microscope type thing.

It was not too long ago that someone was posting images from a dentist x-ray on this forum. He was really excited about the possibility of owning a double strand of natural pearls. None of us really had the heart to tell him his pearls were fake based on the history he gave and the photos. The dentist x-ray showed nothing except that the pearls were indeed perfectly round, nixing the chance of their being natural.

You cannot get any kind of detailed information about the interior of a pearl with dental X-rays. There is just no way this can properly be done unless your dentist, by some very bizarre coincidence, has invested in some expensive high resolution equipment used for jewellry nuking as have some specialized labs. Trust me on this one--I actually own a frightfully expensive dental panoramic x-ray machine, which is a pretty big piece of sophisticated equipment, but totally useless for gathering pearl info.
