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 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.
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:
Due to their delicate nature, pearls have traditionally been associated with purity and innocence.
