5.6. Artificial products
Products which are composites or imitations (5.84).

5.7. Assembled
See composite (5.42) cultured pearl and assembled cultured pearl blister (5.7).

5.8. Assembled cultured blister
assemblages of a purpose-grown cultured blisters (5.49) which have been cut from their shell, the original bead (5.124) upon which they grew being removed and the cavity filled with various types of man-made materials, and backed by a layer of shell, the assemblages being held together by an adhesive; commonly known as Mabe (5.97) or Hankei (5.79) and occur in both fresh and saltwater environments. Not to be confused with cut cultured pearl (5.50). (Mikkelsen, 2003, Walker, 2001).

5.9. Arabian Gulf
An area in Southwest Asia that is an extension of the Indian Ocean located between Iran and the Arabian Peninsula.

5.10. Arabian Gulf pearls
natural pearls (5.118) produced from the Pinctada Radiata (6.52).

5.11. Bahraini pearl
a natural pearl (5.118) from Bahraini waters in the Arabian gulf produced from the Pinctada Radiata (6.52).

5.12. Baroque
an irregularly shaped natural (5.118) or cultured pearl (5.48). Baroque was originally a French adjective used to describe objects or pearls that were not symmetrical in shape. (Mikkelsen, 2003).

5.13. Basra Pearl
a natural pearl (5.118) from the Arabian gulf produced from the Pinctada Radiata (6.52).

5.14. Bead for cultured pearls
a sphere (usually) or other shape (occasionally) originally formed by cutting and polishing a nacreous shell used to accommodate the nacre (5.110) secreted from a cultured pearl sac (5.47). The bead eventually forms the centre of a beaded cultured pearl (5.15).
Note: Atypically, beads formed from natural (5.118) or cultured pearls (5.48) of various types or other materials may be used, however, in such circumstances the product shall be described as containing an atypical bead or the type of bead shall be named, e.g., an ―atypical bead cultured pearl‖, a ―turquoise bead cultured pearl‖.

5.15. Beaded Nacreous Cultured Pearl
beaded cultured pearls are usually nacreous (5.111) formations secreted in the interior of a pearl oyster (5.137). A bead (5.14) is inserted into the mollusc along with a piece of mantle tissue which eventually forms the cultured pearl sac (5.47) around the bead (5.14) which is in turn responsible for the secretion of nacreous layers. The outer layers of beaded nacreous cultured pearls are concentric and composed of a complex scleroprotein named conchiolin (5.44) and of calcium carbonate (usually in the form of aragonite). See nacreous cultured pearls (5.48).

5.16. Bivalve

5.18. Black Cultured Pearl
natural colour, cultured black pearl produced using either Pinctada margaritifera (6.49) (the Tahitian cultured pearl (5.171), Pinctada mazatlanica (6.51) or Pteria sterna (6.59) or other pearl oysters (5.137). The colour is not caused by any subsequent processing.

5.19. Black Natural Pearl
natural colour, natural black pearl produced by Pinctada margaritifera (6.49) Pinctada mazatlanica (6.51) or Pteria sterna (6.59). Colour not caused by any subsequent processing.

5.20. Bleaching
to remove, lighten (make whiter) or alter (e.g., from black to brown/bronze) colour by means of chemical and/or physical agents or light. (Shouguo, 2001, Sanchez, 2004).

5.21. Blister cultured pearl
a cultured pearl, (5.48) that has perforated the mantle of the mollusc and has adhered, through layers of nacreous or non-nacreous secretions applied by the mollusc, to the inner wall of the shell. The subsequently formed layers of nacreous or non-nacreous material are continuous with those of the inner wall of the shell. They are round or irregular in shape and the base of the blister cultured pearl may be worked (5.185).

5.22. Blister natural pearl
a natural pearl (5.118) that has perforated the mantle of the mollusc and has naturally adhered, through layers of nacreous or non-nacreous secretions applied by the mollusc, to the inner wall of the shell. The subsequently formed layers of nacreous or non-nacreous material are continuous with those of the inner wall of the shell. They are round or irregular in shape and are secreted without human intervention (Scarratt 2001). Blister pearls are known in the Arabian Gulf as “Nimro”. The base of natural blister pearls may be worked (5.185).

5.23. Body colour
the dominant, overall colour of the natural or cultured pearl.

5.24. Bombay Bunches
strands of round salt water natural seed pearls (ranging from less than 1 mm to 3 mm)(5.159), mostly with medium to high lustre and well-matching colour. These bunches are known by the trade as Bombay Bunches and are mostly marketed in Europe.

5.25. Bombay pearls
commercial name for natural pearls chiefly from Pinctada radiata (6.52), fished from the Arabian Gulf and Red Sea and exported through Bombay, India (Mikkelsen, 2003).

5.26. Bonding

5.27. Bonus cultured pearl
See Lagniappe cultured pearl (5.93) and Keshi cultured pearl (5.91).

5.28. Buffing

Chaw = (carat weight)² x 88 / no. of Pearls135
The Chaw price depends on the grade and type of pearls.

5.33. Chinese drilling
a term applied to natural pearls that are, in general, button-shaped and drilled (5.55) with two drill-holes. Both drill-holes penetrate the pearl from different points on the flat or less-round side and meet at a point within the pearl.

Saltwater pearls wholesale : Pearls Weight and Pearls measurement

Saltwater pearls wholesale : Pearls Weight and Pearls measurement

saltwater pearls wholesaleWeight
the weight of cultured pearls shall be expressed in:

  • momme,
  • kan
  • liang,
  • carats or
  • grams

The weight of a natural pearl shall be expressed in:

  • pearl grains,
  • liang, or
  • carats ,
  • (four grains are equal to one metric carat) or methgal a unit of weight used in the Arabian Gulf that is equal to 4.5 grams,
  • note also the chaw .

IMPORTANT: It is acknowledged that the weight of a natural or cultured pearl may change over time.

NOTE: It is an unfair trade practice to misrepresent the weight of any natural or cultured pearl or to deceive as to the weight of any natural or cultured pearl. It is also an unfair trade practice to state or otherwise represent the weight of all natural or cultured pearls contained in any article unless such weight figure is accompanied with equal emphasis and prominence by the words “total weight”, or words of similar meaning, so as to indicate clearly that the weight so stated or represented is that of all pearls in the article and not that of the centre or largest one. (reference: saltwater pearls wholesale )

NOTE: The SI (Système International) generally uses the term mass instead of weight. Mass is a measure of an object‘s inertial property, or the amount of matter it contains. Weight is a measure of the force exerted on an object by gravity or the force needed to support it. (reference: saltwater pearls wholesale )

Trade codes for untreated/unmodified natural and cultured pearls that require special care and Pearls Imitations or stimulants

wholesale pearls4.9. Trade codes for untreated/unmodified natural and cultured pearls that require special care.

The code (SC – Special Care) shall only be used within the industry; it shall not to be used for the consumer. The codes are intended to facilitate the insertion of vital information on tags attached to merchandise, on invoices and or other commercial documents used within the trade.

All natural and cultured pearls (5.48 and 5.118) shall have special care advice that includes instructions that they should not be worn while carrying out heavy work, should be kept away from all solvents, should not be wrapped in cotton wool or moisture absorbing materials or subjected to high temperatures as well as ultrasonic cleaning and should be kept away from acids during the manufacturing process. This care advice should be regarded as normal for natural and cultured pearls across the product range and a code is unnecessary. However, there are particular cases were a code would be useful, examples of which are (also see Annex C)

  • Natural Abalone Pearl, (SC). – Often hollow and therefore fragile.
  • Natural Conch Pearl, (SC). – Colour may fade or change if exposed to long periods of sunlight or short exposures to x-rays
  • Cultured Conch Pearl (SC) – Colour may fade or change if exposed to long periods of sunlight or short exposures to x-rays
