KNOWLEDGE OF DIAMONDS
WHAT YOU NEED TO KNOW ABOUT DIAMONDS
One of the most well-known and sought-after gemstones is undoubtedly the diamond, which consists of carbon. Engagement rings, like many others, are typically adorned with diamonds, and there are many fits to choose from. If you already know now what diamond shape you are aiming for in the ring, you will be well on your way to finding the perfect ring.
The 4 c's
The quality of diamonds is judged on the basis of 4 C's. Carat, Clarity, Colour, Cut.
At BOLOU, you meet GIA (Gemological Institute of America) certified specialists, which is a seal of quality for the advice you receive. In addition, we work exclusively with recognized diamond suppliers and always purchased in accordance with international conventions.
Carat is a unit of weight for diamonds and 1 carat corresponds to 0.20 grams. The origin of the unit of weight dates from the time when you only had scales to determine the weight of objects. Thus, 1 carat weighs the same as 1 kernel from the fruit of a carob tree.
Very valuable diamonds are typically very clear and therefore without impurities in the composition with fine light transmission as a result. Impurities also limit the opportunities for grinding.
The clarity of diamonds is calculated on a scale with 12 steps — from flawless to included. At BOLOU, we use VS1 quality as a starting point.
The 4 C's (continued)
Although diamonds are typically associated with transparency, the vast majority of them are actually slightly brownish or yellowish. Transparent diamonds are the most valuable but are also seen in many special colors called Fancy Diamonds.
The color of the diamond has a major impact on its value. Therefore, of course, there is also a grading system for the color of diamonds. In the European and American context, we use a numerical system.
The graphic below shows an overall overview of the system. “DE” is the most valuable color, while “MZ” are the less valuable.
Naturally blue diamonds are the rarest and only 0.01% of the world's diamonds should be blue. The bluish color is due to the presence of boron, and they occur in earth layers four times as far down as ordinary diamonds.
Natural red diamonds are also rare, and only 20-30 pieces are said to exist in the entire world. That is why they are also the most expensive. A 1.56 carat red diamond nicknamed the Argyle Phoenix , for example, was sold at auction for over 2 million dollars.
The cut of a diamond is absolutely central to its appearance. Even a diamond with high clarity and nice color will appear dull if the cut is done poorly. A professional cut brings out the best in an elegant diamond.
The classic grind is brilliant grind, which BOLOU has been used to working with for decades.
