What stone could the blue and black necklace be? I x-rayed them to see the difference between the pearls and them.Hello @cenkbaba and welcome to our forum.
Hard to say with the photos...you should go to a Dentist for better photos. Pearls look amazing under dental X rays.
They are definitively nice looking baroque pearls. The larger and rounder one looks cultured to me, maybe a South Sea pearl.
The x rays display mostly "bands" inside the pearls, so I would say these are cultured...but maybe the x-ray machine displays these bands as a fault....thus, very hard to be conclusive.
Well, very likely you have cultured pearls...and not natural pearls. But if you really believe these ara natural: have them sent to a reputable gem lab such as Liechenstein, SSEF or even DANAT.How lucky are you, the value of pearls is known in your countries, I am offered one tenth of it. )
You can use our guide: https://www.pearl-guide.com/threads/pearl-weight.449304/I think natural pearls are valued in carats (or grams) rather than size. Is there anyone who has information about the average gram value?
That is what I saw as well. But the x rays are not the best. Retesting with dental xrays would be best.The xray views, though low resolution have visible bisected growth fronts at the nucleus.
These are cultured pearls.
You state microscopic examination but have not provided supporting documentation of the type, examiner or protocol.... of the pearls showed white or off-white (cream) bodycolors, while reddish or brownish stains could be found on the surfaces of a few. Microscopic examination revealed overlapping aragonite platelets typically seen in nacreous pearls, as well as evidence of aging, including delicate chalky outer surfaces, worn and peeled layers, and surface cracks in some cases ( figure 7). However, many of the samples still displayed good surface conditions, a high luster, and a strong orient from underlying nacreous layers, reflecting their once-fine quality ( figure 8). ...-

You have also stated the items were aged, but have not provided evidence of this either.
In either instance, these are not tests typically performed by jewellers instead by accredited labs which provide documentation/certification.
At first I was skeptical. Upon examination of the X-ray views, observing size, shape and uniformity, I'm certain these are cultured pearls.
As such, these presumptions are outrageous.
Yes, having a laboratory test will be the definitive result.You state microscopic examination but have not provided supporting documentation of the type, examiner or protocol.
