FAQ - Pearls

Jewellery Domain offers a wide selection of pearls primarily Freshwater and Mabe Pearls

Freshwater pearls

Freshwater cultured pearls are grown in freshwater rivers and lakes. Freshwater molluscs are nucleated using a piece of mantle tissue only.

Mabe Pearls

The Japanese name is Mabe’ gia, which is where the term “Mabe” originated.  Cultivated in Ryukyu Islands of Japan and also in Australia, Indonesia and the Philippine Islands.  To culture a mabé pearl, the farmer needs to insert a plastic nucleus inside the mollusk and cement, or glue, it to the inside of the shell. After about 2-3 years of growth time, the oysters are harvested, and the blister pearls are cut out of the shells. Their nucleus is removed and the inside of the mabé pearl is lacquered and then filled with a resin and then sealed with a mother of pearl backing. You can easily find the area where they sealed the mabé pearl shut, but most jewelry will hide the seam so it will not be visible to the wearer.

South Sea Pearl: South Sea Pearls are prized for their large size, high lustre and colours ranging from white and cream, to silver, pink, lavender and gold. Australia, Indonesia, Myanmar (Burma), Papua New Guinea, and the Philippines are the primary geographic regions for the cultivation of South Sea pearls. South Sea pearl range in size from 9mm to as much as 20mm, with an average size of around 12mm.

Tahitian Pearl: The term "Tahitian pearl" is a somewhat of a misnomer, as this particular pearl variety is not actually from Tahiti. Tahiti is the largest island in French Polynesia, which is located east of Australia, in the South Pacific.  What makes the Tahitian pearls so mysterious is the beautiful colour/overtones those pearls have. The main colour of Tahitian pearls is GREEN with different overtones. Black, green peacock, silver, blue and green etc. The most valuable "black" pearls have what is known as a "peacock green" overtone or colour component.

Man-Made 'Cultured' Pearls

Almost all pearls used for jewelry today are "cultured" freshwater pearls, meaning that they have been "created" with the assistance of human intervention.  A cultured pearl is formed when a small foreign object or irritant (seed nucleus) is embedded in the tissue of a mollusk or oyster by a "seeding" technician.  By surgically implanting this foreign object or nucleus into the tissue of the mollusk, the pearl farmer can induce the creation of a pearl.

The pearls are usually harvested three to five years after the implanting of the nucleus, but it can take up to seven years before a large high-quality pearl is produced.


What Does Jewellery Domain Use on Pearl Grading?

  1. Luster
  2. Shape
  3. Colour
  4. Surface
  5. Size



Jewellers Domain uses The AAA-A Pearl Grading System
This system grades pearls on a scale from AAA to A, with AAA being the highest grade, this grading scale is common to freshwater and akoya pearls only:

  • AAA: Virtually flawless pearl. Surface luster is very high , and 95% of surface will be free from any defect.
  • AA: The surface will have a very high luster, and at least 75% of the surface will be free from any type of defect.
  • A: The lowest jewellery-grade pearl, with low surface luster and/or more than 25% of the surface showing defects.



Jewellery Domain offers many different shapes of pearls. We have baroque, off-round and perfectly round pearls.

Baroque is a general term that indicates a significant irregular pearl shape. Typically, these baroque pearls are the least expensive variety, yet certain exotic South-Sea or Tahitian specimens can be more valuable than perfectly round pearls from other regions. The baroque pearl can be abstract (asymmetrical) in its irregular shape, or it can resemble a stick, cross, or any number of other more "symmetrical" shapes.
Button pearls can represent the Off-round shape of pearls.

Perfect round is to indicate pearls that are "roundish" to varying degrees and considered to be "round" as a basic classification.


Jewellery Domain offers our customers the most beautiful colours of pearls in the market.
Pearls come in a wide range of natural colours (hues) and shades (tones), but some pearls are dyed or irradiated to suit a specific fashion trend or requirement. 


As a mollusc creates a pearl, the layers of nacre do not always adhere smoothly. Sometimes spots and bubbles can appear in the layering process.

Pearls with the smoothest surfaces are the highest-quality, most sought-after pearls. At PearlFans.com, to offer you a range of prices, we offer pearls with a range of surface qualities.


The larger the size of the pearl, the greater its value. Large pearls not only require larger oysters to produce them, but they require much more time to develop inside the oyster, depending on the size of the nucleus.

Jewellers Domain offers different sizes of pearls. Of course, the price varies on different size of pearl as well.

Freshwater pearls range in size from about 5.0-12.0mm, Akoya pearls range from 6.0-9.5mm, Tahitian pearls can reach sizes from 8-18mm and south sea pearls are range from 9-18mm.
