Part of this information comes from personal studyand experience; theother part of this information comes from the help of trusted and knowledgeableexperts.
Inthis article, I will try to play a small role in enhancing your information,especially about the diamond cut.
Thedifference between diamonds cut and diamond shapes
A common misconception among diamond wedding rings, occurs whenwe talk about diamond cuts, people often assume that the diamond cut is thesame as the diamond shape and instantly think of heart, pear, princess, round and ovalshapes of diamonds; and they’llsay: "yes we know all kinds of diamond cuts."
However,when we talk about the diamond’s cut, we do not mean diamond shape at all. Infact, diamond’s cut is about the multidimensional and symmetrical facet of thediamond that can reflect the light that is applied to each of these facets fromthe top. As you can see any diamond shape also has a diamond cut.
Howdo they cut diamonds?
Diamondcutting is a delicate,hand-crafted art that needs alot of experienceand accuracy. As you may have noticed by now, diamonds, like any other stone, do notnecessarily have a smooth, brilliance and beautiful structure from thebeginning and must undergo subtle processes to show its shine and beauty. This process is calleddiamond cutting.
Tostart this process,the diamond experts analyzethe sample size of diamonds with the help of advanced computer software available today. Diamondexperts will analyze the results of computer analysis to decide how to choosethe shape and size of their diamond, and at what point can cut the stone to have a better diamondshape from that stone.
Through this analysis, the cutters will decide which part of the stone should becut as the table (the top flat largest facet), and which aspect should be cut as the girdle(the outside edge) of the diamond.
Afterthat, they start cutting the stone by special tools. For example, they keep thesymmetry of the cuts with some marks. They need special tools for polishing thediamond. Yes, you guessed right!It can take 3 to 4 weeks to cut a diamond.
Thereare four special and general steps to cut a diamond:
Thefirst step is cleaving. In the first step, it is necessary to convert large andirregular stones into small and controllable stones. At this point, the stoneis held in a wax-like mold so that it can be cut into smaller pieces usingblades of steel. Diamond cutters make a groove on the stone and then with thepressure of strikes of the steel blade into the groove can cut it.
Thesecond step is to saw the stone. If it is not possible to cleave the diamond because of the stone’shardness, then the diamond cutters will cut the diamond by using anothertechnique which is sawing. In this stage, they can cut the diamond stone byusing the laser or a special blade that rotating 15000 times per minute.
TheThird step is cutting that is our main topic. After cleaving or sawing thestone then we have a piece of diamond in a suitable size. At this point,diamond cutters can shape the stone with delicate cuts. Obviously, the ultimatepurpose of the cut is that while creating a beautiful stone, these cuts shouldmake symmetrical facets that are able to reflect light from the top surface ofthe stone to give the diamond a unique look.
Itis interesting to know that diamonds are usually used to cut other diamonds. This is because diamondsare the hardest stone and other things cannot cut it easily.
Althoughcutting is the most difficult and sensitive part of this process, but it is notthe end.
Thefourth and final step of preparation of the diamond is called polishing. Atthis point, the cut diamonds are polished using a special polishing wheel,which is covered by a sanding-like plate for polishing the diamonds. This way,the surfaces of the diamond are abraded smooth and then the diamond can showits highest degree of reflection and sparkle.
TheHeart and arrows pattern
Theappearance of the orderly pattern of the heart and arrow, which, can be seenwith the help of special tools, with a red or blue filter, indicates the idealcut diamond. The more symmetricalthe pattern is, the more likely you are to have a sparkly diamond.
Theshallow diamond cut
Whenthe diamond cut is too shallow, the incoming light will move through thediamond and escapes the diamond from the lower facets. In this case, thediamond cannot provide any brilliance or sparkle.
Sometimesthe size of diamonds with shallow cuts seem bigger, but in fact, their glory and beauty are significantly lowerthan diamonds with an ideal cut.
Whenthe diamond cut is too deep, the incoming light will be directed to the bottom ofthe diamond and paled light will leave the crystal from the bottom facet of thediamond. This kind of reflection will reduce the brightness of the diamond.
Othernegative features of deep cuts include that the size of deep cut diamonds seemsto be smaller than the same size diamonds with Ideal cut.
The Ideal diamond cut
Theideal cut is neither shallow nor deep. In this case, the light that isreflected in the diamond surface will return to the diamond’s top facet insteadof reflecting from the bottom and side facets. The ideal diamond cut with its unique brilliance, can actually transform a diamondfrom a simple stone into a precious jewel.
When the diamond cut is ideally, itmaximizes the light that willreflect from the top of the diamond. In this kind of cutting, there is no light thatescapes from other facets and all incoming light will be centralized in thetable facet. For this reason, diamonds with ‘Ideal’ cut are more luminous.
Whichdiamond cut is most sparkle?
If the diamond is cut ideally, thelight rays will move from each face of the diamond to another faced andeventually reflect from the top of the diamond and you can see the uniquesparkle of the diamond.
Although the overall symmetry ofthe round shape diamond enhances the sparkle, we must not forget that even around shape diamond without an ideal cut cannot display this propertyperfectly. The ideal cut should neither be deep nor shallow.

Diamond cutting, which is one ofthe quadripartite parameters (4Cs) suggested by the Gemological Institute ofAmerica's (GIA) to evaluating the diamond value, can at least visually affectthe other parameters.
In other words, excellent or idealcuts can make the diamond look more sparkle even compare with heavier caratweight. Contrary to the public perception, what enhances a diamond's value isnot only its carat weight, because if the diamond is cut properly andbeautifully, then it looks larger and more magnificent than another diamondwith the same carat weight. Keep in mind that a good cut can multiply thediamond's sparkle and diamond with more sparkle seems bigger than its trueweight.
Thus, it is not surprising to see when you want to buy a diamond ring, whatyou end up spending the most on is on the diamond cut.

Forexample, if the diamond facets are not symmetrical, different sides are notaligned, deep or shallow cuts which all have a bad effect on the diamondsparkle and its glory and shine will make the diamond cheaper.
So, the cheapest diamond cut is the poorcut diamond grade which cannot reflect the incoming light from the table facetand most of the light will escape from the underside instead of the top facetof the diamond.
Isthe price related to the country?
In addition to the cuttingstructure that affects the price of this precious stone, it should be noted thatanother pricing factor about cutting is to know where or in which country thediamond is cut. You may be interested to know that some countries are known fortheir long experience in diamond cutting with high quality. Despite such fameand quality so diamonds produced in those countries are also more expensivetoo.
For example, countries suchas Belgium, Russia, Israel, India, and South Africa are known for cuttingdiamonds, while Russian and Belgian diamonds have become world-renowned betweengemologists. So it is clear that the price of diamonds from those countries ishigher.
But it is also important to notethat expensive diamonds or only the name of Russian diamonds do not necessarilyrepresent a better product. You need the advice of a diamond expert to identifyquality and approved diamonds.
