Extracted from the heart of the most inhospitable regions, diamond has fascinated men for nearly 30 centuries. Diamond is pure carbon, crystallised 2 to 3 billion years ago and is the hardest known material in the mineral world. It can only be cut by itself. The inhabitants of ancient India attributed to diamond the power to make you invincible. Greeks gave it its actual name: ADAMUS, the unconquerable. Several months are necessary for a diamond cutter, only heir of a secular knowledge, to make this gemstone scintillate of a thousand fires, with the nuances of the rainbow. To estimate a diamond, four grades are essential: cut, clarity, colour, and carat weight. The combination of these criteria offers infinite possibilities. There is a diamond for all tastes and at every price. Mounted on a ring, it symbolizes triumph and purity of eternal love. For someone engaged......... the stone of promise.
