Diamond
The diamond is a highly prized gemstone, renowned for its extraordinary beauty and brilliance. Composed of crystallised carbon, it forms under extreme conditions of heat and pressure deep within the Earth’s mantle.
What distinguishes diamonds from other gemstones is their exceptional hardness. They are the hardest naturally occurring substance known, giving them outstanding resistance to scratching and remarkable durability.
Diamonds are celebrated for their brilliance and clarity. They are admired for their crystalline transparency and their ability to reflect light. Although diamonds are often colourless, they may also display a broad spectrum of colours and shades, including pink, blue, green, red, black, brown and yellow.
Diamonds are most commonly fashioned in brilliant or round, princess or square and baguette or rectangular cuts, as well as many other shapes designed to maximise their brilliance and aesthetic appeal.
A diamond’s value is assessed according to several criteria known as the “4Cs”: colour, clarity, carat weight and cut. Larger diamonds with exceptional colour, high clarity and an excellent cut are considered the most valuable.
The diamond is the gemstone most widely used in jewellery, prized for its exceptional hardness and its ability to reflect and disperse light.
