Natural diamonds

Natural diamonds formed millions to billions of years ago in the Earth’s mantle and were then carried explosively to the Earth’s surface by kimberlite volcanoes, often with fascinating inclusions inside them.

This rarity gives them a sense of authenticity and uniqueness that many people appreciate. We offer our natural diamonds to clients who wish to own and treasure a piece of our planet’s geological history.

Lab-grown diamonds

Called the diamonds of the future, they are genuine diamonds created in a laboratory from carbon particles, using state-of-the-art machinery and processes that recreate the conditions occurring in nature underground. Chemically, physically and optically they are identical to natural diamonds, even to the eye of an expert gemmologist.
We can offer lab-grown diamonds as an alternative with a lower impact in terms of protecting mine workers.

Our selection

Our precious metals are created and alloyed in our own company. We use gold in various caratages: choose your favourite.

18K GOLD

The finest gold for making a piece of jewellery: it is ductile and resistant to wear. Its preciousness comes from its very high percentage of pure gold; out of 1,000 parts, 750 are pure 999.9 gold and the rest consists of various alloys of other metals, depending on the final colour, such as white, yellow, rose or red.

We are especially proud of our 160pd white gold, which has a very high percentage of palladium, so that the white stays the same colour forever. It is the gold most widely used in Switzerland and Italy.

14K GOLD

14k gold contains less gold than 18k: it is made of 585 parts of pure 999.9 gold, with the rest in alloy. This caratage is also available in various colours.

It is a good compromise between 9k and 18k, and is resistant to scratches and everyday wear. Here too, our 14k white gold contains a high percentage of palladium in order to offer a beautiful white. 14k gold is usually used in the USA and Russia.

9K GOLD

The lowest caratage of gold in the world of jewellery is 9k, made of 375 parts of pure 999.9 gold, with the rest an alloy of precious and non-precious metals, depending on the colour to be obtained.

Its composition does not necessarily make it more delicate than 14k and 18k, since the added alloy also serves to harden it. Its colour remains softer and paler. It is also used in Russia, France and Germany.
