PEARLS

Pearls are gemstones of organic, origin. We differentiate between natural and cultivated pearls based on whether man has been involved or not.
The typical pearly luster is produced by the overlapping platelets of aragonite and film of conchiolin nearer of the pearl surface. This formation also causes the interference of light and the resulting iridescent colors, called orient that can be observed in the pearls surface.Known for men since roman times, due that pearls do not need to be polished or cut to show it´s beauty.

NATURAL PEARLS

Natural Pearls are made by a mollusk as a defensive action resulting from the intrusion of a foreign body. They are opaque and can come in a myriad of shapes and colors. They are made of a fragile material as their structure is made of organic material and water. For this reason, we recommend that they do not come into contact with dryness, perfumes, sweat or other pearls. They should also be worn only on occasion and should be aired well.

CULTURED PEARLS

Most pearls that are currently sold are cultivated, since over-fishing natural riverbeds has caused many of them to run out. All the pearls we use at TOUS are cultured. They are formed by mollusks in a way that is almost identical to natural ones. The only difference is that an artificial core is manually inserted into a mollusk so that this begins to secrete nacre. The value of cultivated pearls is dependent upon quality factors, such as shine, surface condition, shape, color and size. Depending on the varieties and where they are produced, we differentiate between:

CULTURED SALTWATER PEARLS

Cultured saltwater pearls have their origin in Japan, where the Japanese introduced their culturing systems in Micronesia, in the Palau Islands, when these were under their protectorate during the period between the two world wars. Cultured saltwater pearls are formed in various species of marine bivalve mollusks or pearl oysters. As a rule, a saltwater oyster can only produce one or two pearls per shell. Each oyster is nurtured throughout its life cycle on the farm and cleaned regularly to ensure that it remains in good health. At present, pearl farms are to be found in the South Seas, an area stretching from Australia to the Indian Ocean, the French Polynesian atolls, Australia, Indonesia, Japan and the Gulf of Mexico.

1. AUSTRALIAN OR SOUTH SEA PEARLS

They generally range in size between 10 and 20 millimeters of diameter and are produced in the largest mollusk, the Pinctada Máxima. The cultivation period is nearly 3 years.

DID YOU KNOW THAT...?

They are known as the “queen of the pearls” due to their large size and their unmatched beauty. They can come in a range of shapes, but are usually rounded although baroque shapes are also well desired.

2. MABE PEARL

Cultivated semi-spherical pearls that grow attached to the inside of an oyster shell, instead of inside its body. They are produced in sizes that range from 10 to 17 mm in diameter.

DID YOU KNOW THAT...?

When the hemispheric pearl has been covered in with nacre, it is cut, the nucleus is eliminated, the hole is filled, and a mother-of-pearl base is incorporated.

CULTIVATED FRESH WATER PEARLS

Pearls cultivated in pearl farms, which can be found in rivers, bays and lakes all over the world. They are easily cultivated in freshwater molluscs, though as salt water cultivated pearls.

DID YOU KNOW THAT...?

The Japanese began to experiment with freshwater mussels and came to the conclusion that inserting cores was not necessary, only a small pieces of mantle was needed to get the cultivation process started.

1. ROUND

Cultured freshwater pearls without an artificial core inside; they are symmetrical and roll in a straight line. This is generally the most highly prized type of pearl. At TOUS, the most frequently used sizes are between 4 and 9 mm.

2. HALF-ROUND

Perla cultivada de agua dulce sin núcleo en su interior. Tienen forma redondeada pero no llegan a ser completamente esféricas. Encontraremos medidas similares a las de perla redonda.

3. BUTTON

A cultured freshwater pearl without an artificial core inside, symmetrical but flattened in a particular area. At TOUS, they are commonly used for bracelets and necklaces. There is a wide selection of sizes ranging between 4 to 10 mm.

4. COIN

A cultured freshwater pearl with an artificial core inside. The flat shape is due to shape of the artificial core itself that is inserted into the mollusk. The average size is usually 10-12 mm, but we have collections at TOUS where they can reach 16-17 mm. Irregularities in the shape or surface are possible.

5. STICK

A cultured freshwater pearl without an artificial core inside. Its characteristic elongated shape is achieved by the shape of the fabric that is inserted to stimulate the mollusk’s secretion of nacre. The cultivation time is between 1 and 2 years. The sizes vary: between 12-22 mm.

6. RICE GRAIN

A cultured freshwater pearl without an artificial core inside. Its size of only a few millimeters and its elongated, irregular shape are reminiscent of a grain of rice, hence its name.

7. BAROQUE

A cultured freshwater pearl with or without an artificial core inside. Its irregular, asymmetric shape is dependent upon a variety of factors, such as climate or the quality of the water where the mollusk lives. The cultivation time is 2 years.

SYMBOLOGY

INNOCENCE: Due to their delicate nature, pearls have traditionally been associated with purity and innocence. They are often worn as charms for protection against evil and for good luck.

DUE TO THEIR DELICATE NATURE, PEARLS HAVE TRADITIONALLY BEEN ASSOCIATED WITH PURITY AND INNOCENCE.
