In order to make a claim like that, that holds water, the owner will have to prove what he says. At the turn of the century the pearls would be natural or faux. Only a lab can determine if they are naturals- a certificate from the GIA would increase the value and give an appraiser something to work with. The lab does not appraise.
As for turn of the century, provenance could help establish that. If they are natural they will be quite valuable, though pearl size and shape and length of the necklace will contribute to the value. And the clasp.

Identifying Natural Pearls by: Anonymous
A regular appraisal would need to be done, at a lab like GIA that has the technology to identify natural pearls since that might be the case with these pearls. Provenance would also be important.

Florescent Light & Black Pearls by: Anonymous
Hi Betty thank you for your question. First up, before we get into the valuation, could you do something for me please, put the pearls under a florescent light and tell me what happened to the color when you did?
