Gemstone mining is the process of extracting gemstones from the earth, primarily through methods like underground mining, open-pit mining, and placer mining. These methods involve removing overlying rocks and sediment to access gem-bearing deposits, which are then washed and sorted to separate the gemstones
Rough diamonds are sorted and planned by experienced experts who evaluate each stone's quality and determine its potential for gem or industrial use. They use a combination of traditional methods and advanced technology to assess characteristics like carat weight, clarity, color, and shape, then optimize cutting plans to maximize the value of each rough diamond
Bruting is a process in diamond cutting that establishes the girdle outline. Once the height and width of the diamond are determined, it is then shaped along the girdle edge by grinding it against another diamond on a specially designed, high-speed lathe.
In diamond manufacturing, cleaving is a method of separating a rough diamond into smaller pieces along its natural cleavage planes. These planes are areas where the diamond's atomic structure is weaker, allowing for easier splitting. Cleaving is used to pre-shape large diamonds before sawing or to remove imperfections that would hinder cutting.
Lab-grown diamonds can be manufactured in a few weeks to a few months, depending on the method and the desired size and quality. The two primary methods for lab-grown diamond creation are HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). CVD can be faster, potentially taking just a few weeks for a small diamond. HPHT might take longer, possibly up to three months for a larger diamond
