Diamond is the hardest stone in the world which consists of 99.6% to 99.8% carbon. Thus, the diamond is the only existing jewel that is composed of a single element, and not the least! Carbon is the building block of all life on Earth.

We choose the diamond according to different criteria including carat, color, purity or size. The cut of the diamond reflects the personality of its owner as well as his vision of refinement: brilliant, pear, oval, marquise, heart or emerald.
