Diamond Cut: The Basics – Understanding the Technology Chapter 3 “to understand the various measures, tests and evaluations that are made with diamonds, and what the results of this test, diamonds, visual performance, must first have a solid knowledge of using technology and techniques to collect these data. There are many different tools that are used by gemologists and diamond grader, to establish the facts on the properties of a diamond. In this section, the focus is mainly on the most complex and least understood tools, and will also and especially for cutting tools and light developed to determine performance. Non-Contact ScannersThe Sarin machine is the most popular device in a small group of machines, “measuring instruments without contact. These tools are essentially scanners that scan the outside of the diamond and you measure all surfaces smooth stone. They do this by providing many 2-dimensional images of the silhouette of a diamond, and these images, construction of a 3-dimensional model of diamond with action, is capable of being manipulated by the gemologist. Basically, the sarin is able to reconstruct the diamond in a virtual world with great precision. This is very useful for obtaining measurements on the diamond, the examination of the cut diamond, determining the angle and much more. In addition, the software can simulate light sources so that the gemologist diamond model for different types of subject light in different strengths and different (single or multiple), angle, and more. This allows the diamond in a scientific virtual space will be fully analyzed with amazing precision. The data obtained from this analysis is very useful for determining the quality of cut diamonds, and thus its ability to reflect light. that similar Scanners Sarin is helium-scanner and scanner OGI. When Emma Parker & Co., we use gas sarin. DevicesA reflector made simple but essential tools necessary to review and critique of a cut diamond and performance of light are the “reflector device, which is well known of these devices as the ideal scope. The premise of these tools is very simple, they show the fire that is not fully covered by the diamonds in a form that is visible to the naked eye, has increased. This allows a person to observe, “back light” vs. “light leak” light in a diamond. After reading the Emma Parker & Co. Diamond tutorial, you should have a solid understanding of the function of the ideal size and other mechanisms such as the reflector AGSL ASET. If you do not Emma Parker & Co. Diamond Tutorial, please stop reading here and read it in its entirety before proceeding, as will be necessary to understand the following chapters of this tutorial. Link Software DiamCalc software DiamCalc is a wonderful program, which serves the Diamond models, which are generated by a “non-measuring instrument without contact” and put them in a visual model that can be manipulated in various conditions, angles, lighting, etc. later. It may even be the models of Diamond and simulate under “Reflector devices” as the ideal field, ASET, FireScope, and more. This program is able to “skin” of the diamond, if you want, with a look that is very similar to the real diamond. One of the most important aspects of this program is that it allows the user to specify different settings for the diamond trade in force. For example, if we know that the diamond looks good in game 1, but we want to see what would happen if the table is a different size, we can change the table in the program, and you’ll see the effects of these changes on diamond, both visually and by a reflector device. This is an incredibly powerful tool for research and demonstration. GEMEX BrillianceScopeThe BrillianceScope been developed to measure the light back-optical performance of a diamond in direct sunlight. The technology is actually a very simple design and logic. Take a look at figure 3 1Figure 3e 1
This is a basic representation of the internal workings of the BrillianceScope GEMEX. The diamond is set on a round piece of glass. The ceiling above the diamond is then closed, creating a zone entirely white diamond. (See Figure 3 2Figure. 3 2
Is produced with the permission of GEMEXLight fire optical fiber ring and then projected, displayed through an opening in the white hemisphere, through the glass in the tip of the diamond, as shown in Figure 3. 1. The movement of light in 5 specific groups of three points, stopping briefly at each of 15 points. For each set of points a camera at the bottom of the machine until the middle of the ring of light, take a photo of Triple Diamond, an image at any point in the game, “could” another on, so to speak. If these images are taken and recorded, the software breaks each image on a pixel-based, and focuses on three different products. 1. The amount of white light through the stone. This account is for brightness or brightness to the naked eye of the beholder. 2. The amount of colored light reflected through the stone. This account is for the fire, or colored light with the naked eye of the beholder. 3. The “movement” in light of the diamond, or even scintillation. This is regarded as a gloss to the naked eye of the beholder. These results are then compared and collated to form a database controlled diamonds that have been tested on your computer, and the results of these tests, the basis of the classification “comparing” system uses software GEMEX. The result is a report like the one below. Figure 3 3
Courtesy of GEMEX. The results of the report GEMEX indicated above in Figure 3 3, strongly curved, which means that from the bottom of the table in the center of the “high” class includes up to 85 Tested percentile of all diamonds while the scores from the middle of “high” character at the end of the scale to “very high” includes the 86th percentile of 100 all diamonds tested. The GEMEX is an interesting and useful to get a point for an idea of how a diamond in terms of direct light, such as direct sunlight, the direct illumination, etc. GEMEX is because only results limited to make direct light, and that his “comparing notes” is a completely subjective ranking, which is by its nature, always subject to influences that affect the block results in the control group on which the very basis of classification is schematic. Another disadvantage is that the results GEMEX can easily be manipulated by an intelligent user. Something as simple as placing a fingerprint mark on the tip of the diamond may have caused a rating much higher performance in white light, the stone when they were quite clean. A thorough cleaning of diamond and glass is absolutely necessary for a proper analysis. GEMEX checks before each analysis, a report will be issued and dismiss the reports, which show dirty or hazy, but the system can be manipulated with the results, is yet to see our view. After a huge amount of experience with BrillianceScope GEMEX, both as a sales tool and as an analytical tool that I think the technology of image-sound and the result is valid. I also found that consumers expect too much emphasis on the report, and are often found with “Cripple analysis paralysis” and the fear they should be a diamond that scores “perfect 10″ on the BrillianceScope all Letting Go by world-class diamond on a technicality from a data processing subjective, “Classification by comparing the” system. This is stupid and should be avoided. It is important to consider all aspects of a diamond when you buy a stone to power. To do this, consider an analysis of the entire body, which is the BrillianceScope informative, piece, if not essential. ISEE2Figure 3rd 4
Courtesy of ISEE2 ISEE2 machine DiamondsThe is another technology that measures diamonds Brilliance, fire, scintillation and symmetry in a controlled environment mainly by light diffuse light. The inventor states that questions ISEE2 machine diamond to 48 different lighting conditions. The ISEE2 takes 15 frames per second, and analyzes these images to break it to analyze, White Light, light colored, the Movement (scintillation) and optical symmetry (the pattern cut in stone, in this case is the search after the hearts and arrows because the right to cut more often in a 57-facet round diamond traditional pattern) appears. Once widely used ISEE2 machine for both the sale and analysis of diamonds, I can say that ISEE2 results are in line with other technologies, and for a valid test, if they are not overly weighted A consumer’s decision. As used in BrillianceScope evaluation system software is proprietary and unknown to anyone other than the developer. As for BrillianceScope this would normally not a cause for concern, as evidenced by the results in order to scientifically proven by measurements allow the ‘ideal light had been together “with the exception of one piece of information which was the machine ISEE2 by the manufacturer, with Diamonds ISEE2 developed specifically for the sale and marketing its own brands ISEE2 Diamond, which is a facet of 57 Ideal Cut Hearts and Arrows Diamond. This fact does not alter the ISEE2 d ‘technology, the performance results yet to be invalid, it raises more than a shadow of doubt rebuttable on technology that has been tested in a private testing laboratory with two diamonds and diamonds ISEE2 not ISEE2. The problem is in the evaluation report subjective “standard which is employed by the software, proprietary and therefore not recognized by consumers. So far, the independent investigation, including my own extensive use of ISEE2 suggests that the classification made clear that this technology is relatively uniform and exactly when to cut the current position with respect to the major gemological laboratories as the GIA and AGS. As to the scope Brilliance, ISEE2 interesting, if not essential source of information to consider when buying a diamond can. The greatest danger is posed by this technology, too much emphasis is often used by consumers on the importance of results. GIA Diamond DockFigure 3 5.
Courtesy of GIA The GIA Diamond Dock serves as a light source that is used to evaluate diamonds. (Figure 3. 5) The lighting environment is intended to simulate the real “light” as closely as possible. With a combination of direct light and diffused fluorescent lighting to LED, it is capable of simulating the light quite well. This is very useful for observation, photography, and “Naked Eye” light-performance analysis of a diamond. The double-diamond dock as color grading environment. TECHNOLOGIES THAT YOU DO NOT PRETAIN “CUT GRADE ANALYSIS” Triplet traditional jeweler LoupeFigure 3rd 6
Courtesy of Kassoy. Traditional Jewelers Coma “Triplet” lens is a simple tool that can be found in almost any good jeweler. It is a simple hand magnifier that can be a spectator, the diamond under magnification to check easily and in almost any position and situation. The default for this 10x zoom lenses are as different lenses are available for 20x and 30x. This special type of microscope is called a triple “, because the lens actually consists of three different lenses made for greater clarity for the viewer are available. Initially, using a magnifying glass can be difficult, but with a little practice, it is possible to collect a large amount of information on a diamond, just a good, long look at them through a magnifying glass. High-power microscope with high definition camera of Figure 3 7
Courtesy of Kassoy. Koma good source of high magnification is essential for the proper analysis of diamonds. During observation allows a diamond with a 10-triplet loupe is good, with the possibility of a zoom magnification 50x or 60x jeweler for more than diamonds and numerous gaps in learning, as well as its cut. In addition, having the ability to communicate this information to a customer sharing is essential to ensure that the customer feels confident in the diamonds they are looking to buy. When Emma Parker & Co., we use the microscope above. This is a 50x magnification microscope, produced with the glass lenses of the Leica brand, a leading supplier of optical glass. The microscope also has a high definition camera on them, can be taken by the images of inclusions and live video of the diamond can be enlarged streamed. Pictures taken by the microscope to allow customers to see, in remarkable detail the characteristics of diamond enlarged. See examples below … Figure 3 8
Red arrows point to the “Classification of inclusions in diamond. These are the flaws that have contributed to the clarity of the diamond content than that accorded to the classification of laboratory, such as GIA or AGS. Emma Parker & Co., we suggest these inclusions made with red arrows in an image under the microscope, so that our customers can be found easily in the incus their diamonds. ColorimeterFigure 3e 9
Courtesy of Kassoy. Comin market technologies today, advanced tools and accurate for determining the color of a diamond comes from. Tools, “colorimeter” have progressed so far that very closely and demanding. These machines are extremely expensive, and are not used by everyone in the industry. How many of our colleagues, we prefer to Emma Parker & Co., the kind of outdated classification of color, how the GIA and AGS nor used for quality diamonds, a white, a color grading light, and stone master. We believe that certain things must be left to the human eye and the trained observer. Written by Timothy Andrew, Emma Parker & Co. www. Emma Parker diamonds. com
