There are no pearl farms in the Gulf of Mexico. If there were, it would be illegal for them to sell living mollusks. Long ago I investigated relaying pearl oysters. The process required years of quarantine and intensive biomass studies that would assure they'd not displace indigenous species...
I understand the grief of losing pets, having lost and continuing to miss loyal companions.
However, pearl farming at any level is not a simple task.
The oysters seen at pearl parties are not from pearl farms. They are reared in Chinese factories. Previously harvested pearls are placed inside...
Welcome to the club! I've got DISH, so my range of motion is radically decreasing. It's not painful insomuch a stiffening. Ken follows me on Facebook and I'm always flattered when he likes my pearl posts. I'd rather not impose upon a retired person directly, but perhaps posting the call there...
We were ascended to the TEM lab for high resolution imagery of fixed specimens. Though ground breaking, there were limitation issues. Although we were able to observe modified e-cells, the fixer masked otherwise discernible properties. Namely hormones and some proteins. We then evolved into...
I agree to the extent if were exclusive to that. However, gemology isn't though, it's based on the evolution and acceptance of science not perpetuating myths or giving up. Nacre isn't my only issue with the labs. The absence of proper postmortem analysis is limited to hamstringing themselves...
As to point 1, changing the classification from non-nacreous to slightly or moderate aragonite ought not imply a change in valuation in most cases. Of course, there are outliers. I'm not entirely familiar with variations in melo melo, thus unable to speak to aragonitic scale, but can with...
Call for Industry Adoption: The Aragonitic Scale for Pearl Classification
A Necessary Evolution in Pearl Classification
For centuries, pearls have been classified under a rigid nacreous vs. non-nacreous framework. This outdated system fails to acknowledge the continuum of aragonite deposition...
A very good question. I considered this in the differential diagnosis. The valves of Order Ostreidae as we know them are highly calcitic in structure, thus broadly present as white. However in this specimen, the color and surface of the conjunctions appear highly nacreous. Matching this point...
This shell presents with two conjoined pearls. Each would have a term of growth within the vestibular mantle as a loose pearl then were erupted into the extrapallial cavity which eventually became fused to the shell. Upon examination of the inner surfaces, the creature had a considerable history...
Even with my zero fluency in oriental languages, I was bewildered why a knot-less strand of mismatched shaped freshwater pearls with a cheap clasp needed a certificate in the first place.
Of course, giving credence to buyer beware admonishments and the need to get a second opinion.
And yes, implying common sense terminology as opposed to scientific descriptions of the object constituency.
It's clever, but not an elaborate fake. The flame pattern (if you can call it that) is superficial as opposed to radiating from the nucleus.
X-ray analysis would reveal an absence of nuclear material, instead a striated pattern of bisected growth fronts in the views.
