Natural Tridacna Clam Shell Pearl
:
Natural Pearl from the Tridacna Clam Shell
It's unusual for clams and mussels to produce pearls. Only one in 5,000 clams forms a pearl, according to Tungsten Jewelry. When they do, the pearl is quite valuable.
Clam-produced pearls are extremely rare and valuable. They are considered treasured gems because they're so uncommon.
Clams can form pearls because of their shells. A clam's shell has two half shells joined by a hinge, which is called bivalve. The shell holds the clam's soft body, a small foot, a gland and gills used to breathe. Clams feed by continually opening and closing their shells to allow water to filter through. The water contains food for the clam. However, it's this feeding process that also makes the clam vulnerable to irritants, which enter the shell when it's opened. Irritants serve as the basis for a pearl to form.
It's a widely held belief that every grain of sand trapped in a mollusk's shell eventually becomes a pearl. This is false. Mollusks naturally filter sand out when they open and close. If they didn't, our oceans and bays would be loaded with mollusks producing pearls.
When an irritant, such as a piece of shell, parasite or some other particle enters the clam, it triggers a reaction. This reaction causes the clam to secrete multiple layers of a calcium carbonate-type substance, which coats the irritant. Over time, as more layers of secretion coat the irritant; a pearl forms.
Tridacna clam pearls are non-nacreous. The pearls do not have the luster and brilliance of nacreous pearls, but instead the matte-like appearance of porcelain, commonly referred to as porcellaneous.
From a biological point of view, a clam pearl is considered a kind of pearl, being the natural product of a shelled mollusk. However, from a gemological point of view, it is said to be a non-nacreous pearl, also known as a calcareous concretion, lacking the luster and iridescence of "true pearls."
Pearl formation is a defensive response to an irritant, which is covered by a “nacre-like” substance.
Pearls have a matte-like luster of porcelain and are known as porcellaneous. They lack the luster and iridescence of nacreous pearls.
The nacre-like substance is made up of conchiolin and the crystalline form of calcium carbonate known as calcite.
We buy natural pearls directly from the divers throughout the Indonesian archipelago.
Sumbawa Island
:
Sumbawa
is an Indonesian island, located in the middle of the Lesser Sunda Islands chain, with Lombok to the west, Flores to the east, and Sumba further to the southeast. It is in the province of West Nusa Tenggara.
Sumbawa
lies within the Pacific Ring of Fire. It is a volcanic island, including Mount Tambora which exploded in 1815, the most destructive volcanic eruption in modern history (roughly four times larger than the 1883 eruption of Krakatoa, between Java and Sumatra, in terms of volume of magma ejected). The eruption killed as many as 72,000. It also apparently destroyed a small culture of Southeast Asian affinity, known to archaeologists as the Tamboran kingdom.
Remarks
:
This is NOT a cultured pearl
This NATURAL Tridacna Clam Pearl is extremely rare.
This pearl was found by local divers in the pristine tropical waters off the cost of the Island of Sumbawa.
