DISCOVER THE PEARL COLLECTION

 

Birth and culture of pearls

Pearls are formed inside the shells of mollusks, primarily oysters and mussels, when an irritant such as a grain of sand or a parasite enters the shell. To protect itself, the mollusk secretes layers of nacre around the intruder, forming a pearl over time. Pearl farming involves intentionally introducing this type of irritant into the mollusk, followed by careful care until the pearl is ready to be harvested.

Differences between sea pearls and freshwater pearls

• Sea pearls : Derived from marine oysters, they are generally rounder and more uniform. They form in marine environments and are often more expensive due to their rarity and exceptional luster. Famous varieties include Akoya pearls, Tahitian pearls, and South Sea pearls.

• Freshwater pearls : Cultivated in freshwater mussels, primarily in rivers and lakes. They tend to have a variety of shapes, from perfectly round to baroque (irregular). They are generally more affordable than sea pearls.

 

White freshwater pearls

White freshwater pearls are the most classic and recognizable. They are often associated with elegance and purity. Their white color is the result of a natural process in freshwater mussels.

Features :

• Color : Pure white, cream or light ivory.

• Shape : They can vary from perfectly round to baroque (irregular shapes).

• Use : Very popular in necklaces and bracelets, they are worn daily thanks to their classic and timeless style.

 

Pink freshwater pearls

Pink freshwater pearls are prized for their romantic, soft hue. They are produced in a similar way to white pearls, but their color varies depending on water conditions and the minerals present.

Features :

• Color : Pale pink, salmon or intense pink.

• Shape : Just like white pearls, they can be round or baroque.

• Use : They add a subtle touch of color to jewelry and are ideal for more casual or romantic looks.

 

Black freshwater pearls

Contrary to what their name might suggest, black freshwater pearls are not truly black. They can have shades of blue, green, purple, or even bronze. Their unique hue is the result of special treatments or rare natural conditions.

Features :

• Color : Midnight blue, emerald green, dark purple, bronze or intense black.

• Shape : Often baroque, but can also be round.

• Use : Black pearls are ideal for creating bold, modern jewelry, often used in avant-garde designs.

 

Mother of pearl

Mother-of-pearl, also known as nacre , is the iridescent material that makes up the inside of the shells of some mollusks. It is used in the manufacture of jewelry and decorative objects because of its unique luster.

Features :

• Color : Iridescent, with reflections of all the colors of the rainbow.

• Shape : Mother of pearl is usually flat and can be cut into different shapes for jewelry making.

• Use : Used for inlays in jewelry, watches, buttons and other decorative objects, mother-of-pearl brings a luxurious and artisanal touch.

World production

The majority of freshwater pearls are cultivated in China, which represents about 80% of world production. Marine pearls, on the other hand, are mainly cultivated in Japan, French Polynesia (Tahitian pearls) and Australia (South Sea pearls).
