Does ultraviolet lighting give a preliminary impression of whether the pearl is natural or cultured?

 

[pattye]

No, ultraviolet lighting isn't helpful at all. There's no need to take ultraviolet photos at all. Only the photos that show clear photos of the pearls on white background allow us to see the luster, color, blemishes and qualities of the pearl.

 

[BWeaves]

I agree with Pattye.

Thank you for your reply. Honestly, I asked this question because when I shine a violet light on pearls, some pearls glow blue, some pearls glow green, and some pearls don't react at all to the light! This is an experience I learned from examining natural diamonds; they glow blue when exposed to violet light

If the pictures are not clear, please let me know so I can try to take clearer pictures.

In any case, this is not a test for natural vs. cultured in pearls. X-Ray Flourescence (not UV) will determine freshwater vs. saltwater. For natural determination X-Ray and increasingly Microtomography is required, as applied and interpreted by experienced technicians.

Thanks for the clarification. I am not saying that this violet light test is an accurate test, but I am asking if this test can be a preliminary test through which necessary tests can be followed up.

UV is not a preliminary test for natural vs. cultured. Only a professional with the proper experience and technology can make that determination. You seem to have an idea the pearls may be natural. What has given you that impression, sufficient to merit such curiosity?

It's human nature!!! Curiosity drives us to find easy, simple and inexpensive solutions. We learn from our experiences and we will not stop learning until we die. There is a proverb that says (curiosity has killed many cats).

Re curiosity just be aware that natural pearls comprise a very small percentage (less than 5%, probably closer to 1%) of the market. The only bases for suspecting natural origin would be direct purchase from an area or dealer specialized in natural pearls, pearls from mollusk species known not to be cultured, or pearls incorporated in antique jewelry. Even so, a lab analysis and certificate is typically required for resale as a natural pearl.

The smaller pearls strung in a circle appear to be cultured Chinese freshwater pearls.
The large pearls in between these circles appear to be cultured baroque akoya pearls.

Thank you all

My thoughts, exactly.

The clasp appears broken and was originally intended for a 3 strand necklace. I can't help but wonder if it was chosen to deceive someone into thinking these pearls are antique (over 100 years old), which they clearly are not.

It's certainly an odd choice of clasp, Pattye.

This necklace is old, but I don't think it's very old (100 years old). I think it's from the 1970s, and I bought it in this condition about 25 years ago. I haven't had any alterations done to it. The clasp is silver with no stamps or manufacturing marks.
