Manufacturing and Cutting
Once mined, rough diamonds are sorted into industrial diamonds or those of gem quality. Those of gem quality are classified into groups based on size, shape, quality and color. Every diamond has some unique feature so as no two diamonds are the same. After sorting, the diamonds are cut and polished requiring great skill and experience. Belgium, China, India, Israel, Russia and the USA as well as other countries have centres for facilitating this. The more proficiently a stone is cut the more reflected light and brilliance will be seen. The diamond after this process is classified by its cut, color, clarity and carat weight, known famously as the “Four Cs.” By Moti Israeli More on this subject: Israel Diamond Exchange Diamond Certificates Diamond Knowledge
Diamond Types and Grades
Cut: The art of polishing a diamond is to maximize its brilliance and fire (dispersion). A diamond that is cut too deep or too shallow will be less brilliant and ultimately, less valuable. The cut is the only factor of a polished diamond’s value that is controlled by human hands. Colour: The smallest variation in colour makes a difference. Colourless diamonds are the most admired, but diamonds are found in all colours of the rainbow. The rarer the colour, the more valuable is the diamond. Clarity: Most diamonds contain inclusions, which developed during their formation in the earth. The number, type, size, position and brightness of these inclusions can affect the clarity of a diamond. Carat: The weight, which will reflect its size, of a diamond is expressed in carats.Five carats is equivalent to 1gram and is divided into 100 ‘points’.

This pertains to a qualitative diamond with a GIA certificate. The estimation of the value of the diamond can only be done when it is not set in the jewel. Afterwards it is more difficult to estimate its value. When the jewel has a diamond that weighs 0.3 carat or more, most of the times there is a gemological certificate that is attached to it. This certificate is provided by an authorized gemological institute that determines the different parameters of the stone. There are a lot of costs and investments in the transformation of the diamonds from a raw material into a final jewel, and this transformation course includes many parties, and therefore there is a very large brokerage gap.What do you need to pay attention to in the examination of the diamond? The color of the diamond from D- very white to Z – very yellow. The shine of the diamond that is a function of the polishing work, the quality of the rock, and the manner in which it is polished. How do you make the diamond appear to be bigger?You set the diamond when it is surrounded by white gold, and to this you add rhodium which is a member of the platinum family. This gives the gold a shinier look that adds light to the diamond and creates an effect of a bigger diamond.Another method is:You surround the diamond, with little stones. This combination creates the effect of a larger diamond. The vast majority of consumers aren’t aware the importance a professional setting of the diamond has on the final result and on the price of the jewel accordingly.A good setting improves the effect of good diamonds. A bad setting can decrease the value of the jewel by hundreds of dollars. The Israeli diamond setters have a worldly good reputation.Why is it important to see the diamond outside of the jewel? You can’t determine the weight, the color and the cleanness of the diamond when it is set in the jewel, because then part of it is hidden, and usually the defects in the diamond may be in this hidden part, and you can’t see them unless the diamond is loose and standing by itself. In addition, the weight of the set diamond may not match the weight in the certificate.The quality and price of the diamond are determined by 4 criteria: Color, Clarity, Cut, and Carat. The most important factor in the diamond is the CUT that includes accurate polishing angles, exact symmetry and a perfect polish. The quality work causes the diamond to reflect a maximum amount of light, and this gives the diamond its shine and its beauty. Sometimes, a yellowish diamond that is mediocrely cleaned and perfectly polished looks better in the jewel than a white diamond that was poorly polished. Buy the unset diamond and then choose the ring in which it shall be set. When the diamond is set in the ring, you can’t see its true colors, its defects, and the work that was performed on it. Therefore, you need to see the diamond outside of the ring. Only buy a diamond that has a GIA certificate – ask for a copy of the certificate before you buy the jewel. A diamond with a GIA certificate is the real deal that gives the diamond its price and keeps it so for a long time. In every other laboratory, the diamond is worth much less. Compare the number engraved on the side of the diamond to its number in the GIA certificate. You can only do this with a microscope. In the world there are a number of price lists for diamonds that most of them are based on the: The shape of the Diamond, The Weight of the Diamond, The Color of the Diamond, The Clarity of the Diamond.
