Coatings have varied over time...used to be beeswax, later some lacquers. According to Strack, the most common are "transparent polymer film"

I received this baroque where the shiny part of the pearl fades quite abruptly, as can be seen around the top edge. Is this a likely example of coating?

No. That's what I believe a "chalky area", a part where nacre is not deposited well...the mantle of the pearl sac could have deposited calcite instead of aragonite. The Expert in this field (inner working of the mantle) is Dave @Lagoon Island Pearls
I have many freshwater pearls that display this kind of defect.

Correct. Calcite, though not attractive in the same way aragonitic nacre may be, is very important in the early development of molluscs. While calcite is the bane of cultured pearl production, in nature it's important in juvenile and mature to over-mature individuals to maintain shell thickness and strength.

Fireball pearls are generally mature pearls, hence it's not unreasonable to occasionally find calcitic patches.

Sometimes these layers can be peeled away, but it's not with out risk of damaging the underlying surface.

Thank you for the detailed answers guys, I really appreciate it. Love the technical answers!

Thanks Dave! Your input is always valuable and appreciated

Does anyone know what kind of freshwater pearl these are? They’re off-round with a mainly copper body colour but are multicoloured… very interesting in my opinion

 

[pearlescence]

Probably standard bead nucleated freshwaters.

 

[Pearl Dreams]

And I assume natural color.

 

[FireballFan]

Yes bead-nucleated and natural colour.

Hi Pearl dealers,

Do global economic slowdowns impact your pearl business?

Basic living allowance is guaranteed in developed countries, but welfare system in China is unfair. Retired public servants and officials have priority and privileges to enjoy high pensions of up 5000 RMB per month, Farmers who are over 60 can enjoy only 150-300 RMB per month.

Seems like those pension amounts should be the other way around. Without farmers, nobody eats...
