Diamond Knowledge: Diamond is a symbol of love and an indispensable element in industry. Diamond is one of the top five precious stones, do you know enough about it? Let Honway take you through all aspects of the diamond, from how it is created to how to select it!
Abrasives are mainly used for grinding, cutting and polishing, among which diamonds are the most commonly used abrasives due to their ultra-high hardness and wear resistance. Natural and synthetic diamonds have their own characteristics, with synthetic diamonds having a lower cost and similar performance. Diamond abrasives are widely used in cutting, polishing and ultra-precision machining fields to provide efficient grinding solutions.
Introduction Ancient Indians believed that the red in rubies came from an internal, never-extinguishing flame burning within the gemstone. They also considered rubies to be the true “king of gems.” Unlike diamonds, rubies are not controlled by monopolistic companies like De Beers, which regulate supply and spend billions on marketing annually. Despite this, rubies maintain …
Introduction Diamonds are universally recognized as the king of all gemstones. With its cubic crystal structure, diamond possesses the highest hardness of any natural material on Earth, contributing to its immense value. Beyond its unparalleled hardness, the beauty and rarity of diamonds are further enhanced by their brilliance and vibrant rainbow-like appearance. In the current …
Superconductivity is a fascinating physical phenomenon where, under specific conditions, materials exhibit zero electrical resistance and expel magnetic fields completely. The history of this field is intertwined with the contributions of many renowned scientists, significant experimental discoveries, and theoretical breakthroughs. Let’s delve into the trajectory of superconductivity, exploring how this mysterious phenomenon has been progressively unveiled and applied.
The phrase “Diamonds are merely unremarkable carbon” highlights the essential truth that both diamonds and graphite are made of pure carbon, but in different forms, or allotropes. This discovery led to the continued pursuit of methods to artificially create diamonds. After 157 years of research, scientists found that a key factor in transforming carbon into diamonds is the use of catalysts, also known as chemical agents, to accelerate the process.
Diamonds, oh diamonds, so bright and sparkling, how are they made? Natural diamonds are formed through volcanic activity, tectonic movements, and meteorite impacts. But how are synthetic diamonds created? Let Honway guide you through this fascinating journey!
Our Understanding of Diamonds Diamonds, the most precious of the five major gemstones, symbolize purity, loyalty, and eternal brilliance. They are the perfect representation of love, with diamond rings becoming the most important token of marriage. Diamonds also appreciate annually by 5%-10% or even more, making them a beloved luxury item. However, because diamonds are …

Currently, the world’s popular high-temperature and high-pressure diamond synthesizing equipment mainly consists of two-sided tops (belt, which is mainly popular in Europe and the United States), six-sided tops (unique to Mainland China), and splitting spheres (barssplitsphere, Russia) or modified splitting spheres (Gemesis Company). In 1954, before Christmas, the General Electric Company in the United States …
