Colorless diamonds: Diamonds were formed more than 3 billion years ago, deep within the Earth’s crust under intense heat and pressure. These special conditions caused carbon atoms to crystallize, forming diamonds. The diamonds were brought to the surface by a very deep-seated and violent volcanic eruption that is thought to have occurred a very long time ago. Fancy colour diamonds: Created in the same way as colourless diamonds, with the exception that colored diamonds undergo unique geological conditions where chemicals […]
WELCOME DEAR FRIENDS It’s all over the forehead of an autumn day when I had a diamond of one carat for the first time in my life. Of course, I’ve seen diamonds before, mostly in jewelry, but I never had such a large stone back in my hand. Until then, jewelry and gemstones did not interest me at all, and then there was a magic that continues today. It’s hard to describe the fascination when you see something for the […]
Most popular diamond shape is the round brilliant, originally developed by Marcel Tolkowsky in 1919 with a total of 58 facets. There are, however, many other diamond shapes available which are known as a fancy cut, including popular choices such as princess cut, emerald cut, oval and baguette. Deciding the shape of the diamond is a matter of personal taste and style. Over the past century, diamond cutters have perfected the round brilliant cut diamond using advanced light theories and […]
The 4 C’s of Diamonds Luxury never really interested me in my life, but on the contrary, I always appreciated modesty.

My obsession with precious stones (gemstones) led me to read all about cutting and polishing diamonds for years, as well as the equipment used in the production process. In the beginning, it was all new and mystical to me because it is challenging to get into the circle of people who are engaged in this job. Everything in this business is a secret, and many things are kept and skillfully hidden by them. Even the cost of the equipment itself, lasers are hiding from ordinary people and are not publicly available. At the beginning of the 1980s, a Japanese businessman, Mr. Takanori Tamura together with a skillful cutter (polisher) called Higuchi came up with the idea of improving the round brilliant cut. They represent the world for the first time so-called Eight Star cut, which later turned into the famous Eight Harts and Arrows cut. It was a real revolution in the industry. Cut brought to perfection. Mr. Tamura did not have such sophisticated equipment as it is today. DCD Group upgraded this cut by being a strictly accompanying line of symmetry, with colossal precision, increased the size of the diamond with its patent. We are looking forward to great commercial success because the essence was to enable the purchase of a diamond for less money.
Cutting and Polishing There are not many places in the world where diamonds are cutting. I would only mention a few places, which are: Antwerp in Belgium, Smolensk in the Russian Federation and Surat in India. Jewish masters moved their production from Ramat Gan (Tel Aviv) and New York, mostly to Surat in India due to cheaper workforce and proximity to mines.
