Polishing and cutting lab diamonds: The world of diamonds is a huge and rich world of content, of various topics and of parameters on the basis of which the value and price of each diamond and diamond is determined. Forms of polishing and cutting lab diamonds are among the most important parameters in determining the value of lab diamonds. It is not for nothing that this is a very accurate test, since today the good, high-quality diamonds and those that get high scores have a very high value and this value will also determine the price of the diamond itself or the jewelry that incorporates the diamond which can be diamond necklace.
In order to estimate the value, you need to know a lot of things and topics, and of course you need to engage in the diamond field professionally. In recent years, and with the beginning of the production of diamonds under laboratory conditions (and not in their mining from the earth’s) the discourse on the same parameters and how they can be applied and accepted to lab grown diamonds also arises again.
Lab grown diamonds today have the same criteria of polishing and cutting and these operations are performed similarly to the way they are made in natural diamonds. These rules may change over time and there will be another way to evaluate the diamonds produced in the labs.
Introduction – Polishing and cutting lab grown diamonds
When we talk about the shape and cutting of laboratory diamonds, we are actually referring to its external shape. In the professional world there are dozens of shapes of diamonds and the way to get to each one is through different cutting and polishing. Until a few years ago, polishing was done manually by certain tools, but today, thanks to technological development, it is possible to use computers that examine closely and increase the surface area of the diamond – which allows the polishing to be performed much better and more accurately than before.
The polishing shape and final appearance of the diamond is decided in such a way that the diamond will reflect light in the maximum way, meaning that it will have as many wigs on the surface as possible so that each of them will reflect light in the best way. After deciding on the final external shape – it is possible to approach the work of cutting and polishing and choose the way in which the goal will be achieved.
Round cut diamonds
These diamonds enjoy both high popularity and high prices. When the measure is the reflection of light, then a lot of light will be reflected from a diamond whose surface area is round. At the same time, the craft of cutting and polishing to achieve a round surface is challenging and is considered extremely difficult (hence the high price of the diamond). These diamonds are very common in the form of a drop (a wide or narrow body that gets even narrower at the top) and many calculations are made before and during its polishing in order to reach the perfect shape. In the process, a thought is given to obtaining a proportional shape that will not do any injustice to any part of the diamond and, of course, that its appearance for those who do not have a professional eye in diamonds will be no less perfect. Thanks to computers and magnifying software, it is easier to get round and perfect diamonds and they integrate well with the diamond production that takes place in a scientific laboratory anyway.
Square or rectangular diamonds
Here, too, it is a very common form of polishing due to a very important feature – the loss of as little material as possible. That is, when polishing – there is not much raw material that is lost and the finished diamond will be very similar in its shape to the rough diamond before polishing. In many cases, polishing actually makes the diamond pyramid-shaped, and thanks to this shape, it is possible in many cases to polish two diamonds from one block of raw material. The square diamonds also have a special, beautiful and magnificent shape and it does not fall short of its shape and transparency from that of the round diamonds. When to choose a round diamond and when a square? Of course the answer to this question is based on the personal taste and purpose of the diamond. Diamonds of this type will be inlaid, usually in jewelry where the end of the pyramid is the one glued to the jewelry itself and thus prevents the entire diamond from moving or falling.
Marquis polishing – the oldest polishing of all!
This is a polishing method that has been in use since the beginning of the 18th century. The diamonds are obtained in this polishing in a perfect, beautiful and special almond shape and have a charm that is not seen in other forms of diamonds. Those who are interested in this form of polishing are looking for an elegant, pleasing to the eye diamond shape that radiates both everyday and luxury. A combination of two poles in one diamond. It is very important to know and note that in the shape of the marquise sharp edges are obtained that can injure and therefore one should pay attention to what the use of the diamond should be, before deciding to choose this shape. It is important to consult with professionals to make sure that the choice of Marquis is indeed correct and appropriate to the circumstances.
Emerald cutting – a sense of antiquity
A stair cut adopted by the world of diamonds from the beautiful and special emeralds. When you watch movies and see them as rectangular and stepped gems – this is exactly the form of emerald cutting. In ancient times it was easier to polish and cut the diamonds in the stairs than to polish a straight wig and hence the establishment of this method.
In addition – in the emerald cut a very large diamond area remains unharmed so not much raw material is wasted. The steps on the sides of the diamond create a special and interesting light reflection and the shape looks perfect from every direction. The disadvantage of this method is that due to the same steps that characterize the cut – it is easier to notice any small defect both on the surface and on the inside of the diamond.
Contrary to the thought that this form of cutting originated in romantic or couple ideas – the initial intention of this cut was to remove sediment and defects from the surface of the raw material. Over time, the cuts have evolved and today there are several types and shapes of hearts – elongated, transverse and those that are sub-dimensional.
This is not an easy polishing method at all, since in order to obtain a symmetrical and perfect heart, it must be examined thoroughly throughout the polishing many times, which is very difficult to achieve by polishing very small diamonds. Indeed, when purchasing or examining very small heart-shaped diamonds, it is possible, by looking at magnifying devices, to notice the asymmetries that cannot be noticed by the eye alone.
How to choose shapes for polishing and cutting lab diamonds?
As mentioned, the diamond is chosen according to personal categories based on personal preferences or according to the future use of the diamond. There are forms that are important in such and such choices and therefore the choice should be based on all the parameters related to the use of the diamond. The laboratory diamonds can also be produced and polished in the manner of the roads and under the same parameters in order to achieve perfection both in appearance and shape. Today, when laboratory diamonds are obtained with high quality and high degree of transparency and cleanliness of the diamond they are very similar to natural ones but their production process is much shorter.
There is no doubt that with the development of the field, additional methods of cutting and polishing may also develop that will bring with them diamond shapes that are not known today. when will it happen? time will tell.
Even now, there is no doubt that the lab diamonds bring with them a lot in new and promising lines to the world of jewelry and diamonds and the road is just beginning. The research is progressing and continuing and there is a lot to look forward to over time.
