A Brief Introduction to Diamonds
Diamonds are the crystallised form of carbon and develop within the Earth's mantle - the layer between the crust and core. Between 150 to 200km below the surface, extreme pressure crushes carbon atoms together into a covalent bond, changing the element’s structure and forcing its atoms into a new one. Every carbon atom is covalently bonded to four other atoms. Over the course of time, under intense heat between 900 and 1,300 °C, more and more atoms bond together and form diamond crystals. The strong atomic bond is the reason why diamonds are among nature’s hardest and most durable materials.
After the formation process, which can take billions of years, diamonds are pushed up through the Earth’s mantle and eventually into the outer crust by volcanic eruptions. Diamond bearing pipes of igneous rock, known as the Kimberlite, allow the transport of diamonds to minable depths. Once extracted from the ground, diamonds are cleaved, cut and polished to enhance their beauty. Today, approximately 130 million carats are mined annually, in countries including South Africa, Brazil, Botswana and IndiaLearn more about the history of Diamonds
After a rough diamond is extracted from the ground, it is assessed to determine its suitability for being cut into a specific shape. Only when it has been cut, finished and polished it can be graded by a Gemologist, with quality proven by a diamond certificate. Diamonds are assessed under controlled conditions, based on their characteristics such as colour, polish, dimensions. Steven Stone sells only diamonds certified by GIA - the strictest body with ethical standards and the highest integrity of certification.Learn more about Diamond certificates
Steven Stone’s collection offers a wide selection of engagement rings, wedding rings, pendants and earrings with diamonds in various shapes. The shape of the diamond refers to the stone viewed from above and is the most significant feature, as it affects the diamond’s brilliance. The classic, extremely versatile and most popular shape to wear is the Round Brilliant cut diamond, followed by the beautiful square Princess cut diamond. If you like the vintage look in stones, the perfect choice would be step cut diamonds with larger facets, such as the Emerald, Asscher or the Cushion cut. Below is a list of the different diamond shapes available at Steven Stone.
Colour, Clarity, Carat & Cut are vital when determining the quality of a diamond. These quality categories contain information such as inclusions, weight, shape, cloudiness. All of these factors affect the stone’s visual appearance and therefore, the price.
