Mabe Pearls

Mabe Pearls are large, hemispherical cultured Pearls that grow attached to the inside shells of oysters. Mabe Pearls are of hemispherical shape, grown against the inside of the oyster's shell, rather than within its tissue. Mabes occasionally appear in nature. Cultured mabes are cultured intentionally by using a hemispheric nucleus, rather than a round one; and by implanting it against the oyster's shell, rather than within its tissue. Mabe Pearls are suitable for casual and formal occasions depending on how you coordinate. That is the Mabe Pearls. 

Hemispheric Shape - A Distinct Characteristic

The Pearl then develops in a hemispheric form, with a flat back. While in the oyster a Mabe Pearl is actually considered a blister Pearl not a mabe Pearl. After the blister Pearl has been 'worked' it then becomes a mabe Pearl. Blister Pearls are worked by cutting the Pearl out of the shell with a circle-bit drill.The nucleus is then removed and replaced with a resin.The back of the Pearl is capped with a piece of mother-of-Pearl to complete the Mabe Pearl.

What is a Blister Pearl?

A blister Pearl (also called a button Pearl) is a Pearl that developed attached to the inside of a mollusk's shell. This type of Pearl must be cut off the shell, and is therefore hemispherical. Because of their shape, blister Pearls are mostly used for earrings.

What is Rainbow Mabe Pearl?
In general, you would think that all Pearls are round shaped or spherical. However, Mabe Pearls are not completely round. They come in various shapes. The subtle hues give it a unique presence, a quality that can't be found in other Pearls.

Mabe Blister Pearl
Some people call blister Pearls "Mabe Pearls". This is only accurate if the blister Pearl was grown in a Mabe oyster. The Mabe oyster is a penguin wing oyster that produces blister Pearls with better luster, iridescence, and color than other species. Mabe Blister Pearls have a rainbow spectrum of colors on their brilliant nacre - hence they are also called Rainbow Pearls. Nearly all Rainbow Mabe Pearls sold today are semi-spherical Pearls or so called 'The Mabe Blister Pearl' These are hemispherical, taken from Mabe oysters, and give off a unique rainbow-colored sheen. Thanks to developments in Pearl culturing technology in recent years, we now have been able to cultivate a few spherical Mabe Pearls, in addition to the original hemispherical shape. Though Mabe and South Sea half Pearls are the same shape, we make a clear distinction between them, as they are cultivated from different species of oyster.

Blister Pearls are left attached to the shell backing and the shell is polished to a smooth surface. Blister Pearls are often cut into lovely freeform shapes, showing both the inner shell and the Pearl. They can also be cut so that just the round Pearl is left. These are in essence "half-Pearls" and are often used in earrings, rings, and pins where a flat back is desirable.

Mabe Pearl is also used to refer to the process of creating a half-Pearl - even when the Pearl was not grown in a Mabe oyster. These half-Pearls are manufactured by a specific method - the cultured blister Pearl is cut off the shell, the manually planted nucleus is extracted, the inside of the nacre coating is painted, the void left by the nucleus is filled with an epoxy, and the Pearl is finished by covering the bottom with a polished piece of mother-of-Pearl.

Back to 'All About Pearls' Summary
Ever since the ancient Egyptians first started creating jewelry, Pearls have become one of the highest regarded gemstones. Even today Pearls still hold their value due to the rarity of "mother nature" creating this form of jewelry. Pearls are created from a core. The core of a natural Pearl is simply a fragment of shell or fishbone, or a grain of sand that strays into the unsuspecting Pearl oyster's shell. To protect itself from this irritant the oyster secretes multiple layers of nacre, forming a Pearl...
