Culture pearls are born from the hand of man. A secular gesture behind the most beautiful ornaments ever carried by women around the world.
But sometimes nature is capricious and refuses to lend itself to the game of transplants. This is where the Keshis are born.

To understand the creation of a keshi you have to go back to that of a culture pearl. In order to produce a very round pearl, the grafter inserts inside an oyster perlières two natural elements: a nucleus (mother -of -pearl: the support of the future pearl) and a graft (small end of the coat of the oyster of the oyster : the mother -of -pearl manufacturer). To protect itself from the intruder (the nucleus), the oyster perlières activates his graft to create successive layers of mother -of -pearl around the nucleus and definitively isolates his invader. A pearl was born.

But then the keshi in all this?

Sometimes nature is playful and the oyster decides to manage on its own. She rejects the nucleus that she does not recognize and keeps only the graft. The graft, whose primary function is to produce mother -of -pearl, is taking action without the round support of the nucleus. He gives life to a delicate, unique and so special Keshi.

A keshi is therefore only composed of mother -of -pearl like the "wild" pearls that the lucky ones found in wild oysters a long time ago!

The gold rush ... Keshi!

The creation of a keshi is unpredictable. Its size, color and shape are only the fruit of chance and no one can know when and how it will form. Because its production is uncontrollable, it is much rarer and difficult to obtain than culture pearls.

Long shunned by the perlicultors and buyers, the Keshis were then rejected in the water! A shame when you know that today they are very sought after. Victim of their success in the Pacific Islands as well as in Europe, Keshis are a precious and desired commodity of jewelry creators.

Sensuality that breaks codes

The golden rule? There are not any. Keshi is carried alone, in superposition, accompanied by semi-precious stones, in adornments, mixed with other jewelry, at the beach, in the city, at work, on vacation, in chill or in the evening ...

Unique between a thousand and authentic like us, women, each Keshi creation has its own character, its own vibrations. Finally wear the original pearls that look like you.

Composition of our jewelry

We have always believed in total transparency when it comes to sharing the way our jewelry is created and sourced: it is fundamental to know what we wear in contact with our skin every day.

This overview gives you the keys to understanding our choices of materials and the one that suits you best.

The plating of gold is to place on the jewelry, 18 -carat gold, thanks to the passage of an electric current. This galvanoplasty method, or also designated electrolysis, can be repeated on the jewelry so as to obtain varied gold thicknesses on it.

In the jewelry industry, the term used to quantify the veneer is the micron which corresponds to a millionth of a meter. A single veneer procedure will ultimately give a gold plated equivalent to a micron. The standard in France is 3 microns.

Developed in the United States, Gold Filled is a thick layer of 14-carat gold mechanically pressed or affixed hot on a brass base.

More resistant that gold plated, Gold Daughter gives jewelry the noble appearance and aesthetic characteristics and hypoallergenic gold.

18 -carat gold jewelry is made from pure gold, which is more malleable. In order to increase its resistance, we add, to the precious metal, a quantity equal to 25 % copper and silver. The result is a golden jewel of great durability and a unique reflection.

Very resistant Against breakage, corrosion, claws and wear over time, 18 -carat gold jewelry can be worn by a large majority of people Without fear allergies.

The word "rhodié" comes from the name of another precious metal: the rhodium.

Rhodier Money is a veneer process used in jewelry which consists in covering by electrolysis a 925 silver jewel (also known as sterling silver or solid silver) with Rhodium to maintain or restore the bright appearance of jewelry.

Covering a silver jewel with rhodium is mainly used to avoid oxidation of money. Indeed, without rhodiage, the surface of a classic silver jewel oxidizes much more quickly in the air and in contact with the skin.
