In underwater pearl farms, the cultivators carefully embed bits of mantle tissue and mother-of-pearl seeds or shell beads into the insides of bivalve mollusks, for example, clams.

After this “surgery,” the clams convalesce in a “healing facility” for four to six weeks. They are then exchanged to confines somewhere around seven and ten feet submerged. Here, they are permitted to develop for one to six years. The development time frame relies on upon the farm conditions, the mollusk species, and the fancied pearl result.
Cultured pearls can be recognized from naturals by a X-ray examination at a gemological research facility. This can uncover the seed used to begin the arrangement of nacre layers. (It may likewise be conceivable to see the seed if a pearl has a drill gap).
False or fake pearls are simulants. While cultured pearls are genuine pearls, simulants are not pearls by any stretch of the imagination. With different surface medications, materials, for example, glass, shell, and plastic can be made to impersonate a pearl’s luster. Fake pearls have been around for quite a while.

The Pearl Science Laboratory plays out a few tests on arbitrary pearls all through the strand to decide its general grade. The pearl surface is amplified and checked for considerations. The nacre quality and profundity is checked, by using optical filaments and x-rays. The luster is controlled by correlation. In the event that all tests are performed and each quality element surpasses or meets the criteria, the strand is considered Hanadama grade. It is essential to note that lone roughly 50% of the strands submitted for Hanadama investigation are acknowledged accordingly by the Pearl Science Laboratory.
How Hanadama Pearls Are Graded And Selected

Every pearl in any given strand will fluctuate, and each Hanadama strand will constantly have pearls with nacre profundities running from .40 mm to 1.00 mm or more. It is difficult to ensure predictable nacre profundity inside a solitary strand.
The Beauty Of Hanadama Pearls
