Since ancient times, the pearl has been considered the most magical of gems. Today, cultured pearls are an essential part of any woman’s jewelry box.
Pearls, unlike other gems that form in the depths of the earth, form inside an oyster and do not need any treatment or polishing to reveal their beauty.
In natural pearls, their formation begins when a foreign object, such as a grain of sand, enters the interior of an oyster, and to avoid irritation, it begins to coat it with the nacre it secretes.


Since the beginning of the 20th century, man learned that by introducing a small piece of nacre into the interior of an oyster, he could provoke the formation of a pearl instead of leaving it to chance. Since then, millions of pearls have been cultivated in the bays of Japan and the South Seas, but only a small proportion of oysters survive during the years necessary to form a quality pearl. Only 20% of oysters give rise to a pearl for jewelry, and only 5% will reach sufficient quality to meet the requirements of Perodri Joyeros.
There are several aspects to consider when evaluating the quality of a pearl. This is a task that at Perodri Joyeros is carried out by experienced professionals who are responsible for selecting the pearls that meet the quality required by Perodri Joyeros, rejecting those of inferior quality.
TYPES OF PEARLS
In nature, there are various types of pearls depending on the type of mollusk that produces them, which makes them different in both size and color.
