A diamond is the hardest naturally occurring substance and consists of pure carbon. It forms deep within the Earth under extreme pressure and high temperature. Due to its brilliance and rarity, it is primarily valued as a gemstone, but it also finds applications in industry and technology.

The quality and value of a diamond are assessed based on the four Cs:Carat (ct) – The weight of a diamond, where 1 carat (ct) = 0.2 grams. Larger diamonds are rarer and more valuable.Color – Diamonds are graded from colorless (highest quality) to yellowish or brownish. The color scale ranges from D (colorless) to Z (heavily tinted).Clarity – Describes internal inclusions and external imperfections. The fewer inclusions, the more valuable the diamond. The scale ranges from "Flawless" to "Included" (significant inclusions).Cut – The cut influences the brilliance, i.e., how well the diamond reflects light. A precise cut maximizes the stone's sparkle.

Lab-grown and natural diamonds are chemically and physically identical, but differ in their formation. While natural diamonds form deep within the earth over millions of years, lab-grown diamonds are artificially produced in just a few weeks. Specialized testing equipment makes it possible to detect the difference. Subtle characteristics, along with the assurance of owning a genuine diamond, make natural diamonds more valuable. Furthermore, transparent diamonds eliminate any doubt. FELIX AMAR sells exclusively natural diamonds.
