Not necessarily. Pricing is very subjective. It's a clam pearl. There is no dispute as such so there is no great need for a lab report. You could insure it for whatever you think it's worth. The roundness adds value, but overall it's medium quality. I wouldn't expect high offers, especially in...

Good images. I'm impressed by the near roundness. The colour and lustre are alright, but not outstanding. Again, this is typical for a clam pearl so it's not necessarily a discredit to it's quality. When pearls mature they'll get larger in size, but they'll also show their age by giving up some...

We can't have baby fine skin as adults. Pearls can't either. Thick nacre is great, but juvenile surfaces are infinitely more lustrous, uniform and valuable as gemstones.

Congratulations. This pearl presents with features typically observed in it's class. Unlike other gemological pearl types, these bivalves are distinguished by having the two halves of the shell equally sized. In pearl reared species, normally the left valve is quite flat while the right is...

They are dyed freshwater pearls. Who are the experts you claim? Most experts have no issue being named in association with their identifications. In fact, experts have weighed in here with correct ID and rationale. Black pearls are not and never have been produced in Japan and likewise, the...

I have no data on the subject, but if I we're to speculate, I'd suggest the single pearl stud is the most commonly worn ear accessory piece among women. If anything, it's the greatest allure.

There's no need to be concerned. Regular cleaning and open air drying is always recommended for most any strands or pearl pieces.

EDXRF analysis identified the ion returned to the instrument. Calcite. LRS supports this. Nothing in the report suggests this is a pearl of any origin, but instead confirms it is a section of a shell. In geometry and nature, a deviation of .1mm from a nearly 5cm object is mathematically...

I'm not dismissing history, you've neglected to specify it. If you're here to learn, great then heed what experts tell you. That's not the impression I'm getting here, which is wishful thinking over trinkets. By your own admission, you know nothing about pearls. You've spent several paragraphs...

This strand presents with extensive damage. Some cracking and peeling is visible, but the most affected areas radiate broadly around the holes. Reverted calcite occupies the space between the nucleus and pearl nacre. Reversion is sped up by heat, sunlight or moisture... especially chemical...

These scored 10-0 : FW v Marine origin. I found it impossible to mark a single point for natural origin, nor even a contentious split. Conclusion : Freshwater pearls. Rationale : Unsubstantiated provenance. Conjecture. Observations lack scientific merit. Complete absence of a protocol or...

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...

My thoughts, exactly.

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...

This is a first draft, hence incomplete. I invite your commentary and criticism that this may be refined.

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...
