The facts
What mabe Pearl actually is
Mabe Pearl is classified as assembled product: a hemispherical nacre dome cultured against the shell, cut out, backed and capped, with the composition Aragonite nacre dome, wax or resin fill, mother-of-pearl backing plate. It crystallises in the aggregate (orthorhombic aragonite) system.
Colour comes from nacre interference; strong in Pteria penguin and abalone mabe, which is also what a laboratory looks at when it is asked whether a colour is natural.
Refractive index 1.52-1.69. Specific gravity around Variable, assembled. Cleavage: none. Those three numbers separate it from most of what imitates it.
Where mabe Pearl comes from
Mabe Pearl is produced at Pteria penguin mabe, Ryukyu Islands, Japan and Indonesia, Haliotis iris mabe, Nelson and Marlborough, New Zealand and Pinctada maxima mabe, Broome, Australia.
The locality is part of the description, not a footnote — two stones of the same weight from two of these places are not the same stone.
How mabe Pearl is treated
An assembled stone by construction and must be sold as such. The nacre dome is thin and wears through at knuckles and cuff edges, so ring use is a durability problem. Not CITES. Cheaply imitated with plastic and epoxy domes.
Treatment changes value, sometimes by a multiple, so it belongs in the description before the price and not after the sale.
What mabe Pearl is confused with
In the trade mabe Pearl is most often mistaken for, or substituted by, Round cultured pearls, Plastic domes or Natural blister pearls (which are attached to the shell and not backed).
The separation is rarely a matter of opinion: refractive index 1.52-1.69 and specific gravity Variable, assembled settle most of it in a minute, and magnification settles the rest.
What mabe Pearl is used for
Demand for mabe Pearl comes from jewellery, which is why one price per carat never covers it.
We quote each application in the unit that trade actually buys in, by the carat.
Durability and care
Mabe Pearl is 2.5-4 on the Mohs scale, with none cleavage.
Below about 5.5 a stone will be scratched by ordinary household dust, which is largely quartz. That does not make it unusable — it makes it a pendant, an earring or an object rather than a ring worn every day.
Warm water, mild soap and a soft brush. Avoid ultrasonic cleaners on anything fracture-filled, stabilised, dyed or visibly included.
What mabe Pearl costs
As a guide, mabe Pearl trades around $20-400 per piece; large fine abalone mabe $300-1,200.
That is a range, not a quote. Colour, size, clarity, cut and origin move the figure a long way inside it, and the only honest price is one given against a specific stone. Send us what you need and we will price it.
Questions
Is mabe Pearl treated, and how?
An assembled stone by construction and must be sold as such. The nacre dome is thin and wears through at knuckles and cuff edges, so ring use is a durability problem. Not CITES. Cheaply imitated with plastic and epoxy domes.
Where does mabe Pearl come from?
Pteria penguin mabe, Ryukyu Islands, Japan and Indonesia, Haliotis iris mabe, Nelson and Marlborough, New Zealand and Pinctada maxima mabe, Broome, Australia. Origin affects price, so we name the locality rather than the country on every quote.
Is mabe Pearl hard enough to wear every day?
Not really. At 2.5-4 on the Mohs scale it is softer than the quartz dust in ordinary household dirt, so it scratches with wear. It suits pendants, earrings and objects better than a daily ring.
How much does mabe Pearl cost?
Indicatively $20-400 per piece; large fine abalone mabe $300-1,200. Colour, size, clarity and origin move the price a long way within that, so treat it as a range and ask for a quote against a specific stone.
What is mabe Pearl confused with?
Most often Round cultured pearls, Plastic domes and Natural blister pearls (which are attached to the shell and not backed). A refractive index of 1.52-1.69 and a specific gravity near Variable, assembled separate it quickly.
