JTR Jewellery Reports are essential tools to improve the Jewellery Buying Experience
Jewellery Reports are the preferred report type when there is more than one diamond on a jewel or because the diamonds are very small. Jewellery reports require considerable experience and proficiency. Having a diamond attached to a jewel makes the grading process difficult. At JTR, we rely on technology and continue our research to solve these complex problems. Let's take a closer look;
AUTHENTICITY OF DIAMOND
JTR has conducted a significant amount of research to determine the source of the diamonds on the jewellery, and as a result of this research, it has achieved to identify chemical fingerprints of natural diamonds on jewellery.
In order to detect the source of the set diamonds on the jewellery, a special wavelength laser is sent one by one and the reaction of the diamonds to this laser is analyzed. This process is called photoluminescence spectroscopy. With this technique, chemical fingerprints are detected showing that diamonds are formed in nature. If an unnatural diamond is detected, this diamond is clearly stated in the JTR Jewelry Report or the product cannot receive a Jewelry Report. JTR continues to carry out research for the detection and detection automation of Natural and Lab grown diamonds.
Carat is the unit of weight of a diamond. One carat equals 0.2 grams. JTR Jewelry Reports indicate the total carat of diamonds on the jewelry. In addition, if requested, the carat weight for each group is calculated and validated according to the characteristics of the diamond groups specified in the JTR Jewelry Reports.
JTR's Jewellery Reports make an endless effort to analyze the jewellery in the highest possible resolution. For this reason, JTR has developed mathematical methods for the theoretical calculation of the weights of diamonds on jewellery.
These calculations significantly increase the time required for the jewelry reporting process. For this reason, these analyzes are performed only if requested. In cases where the Carat Calculation is not requested, it is clearly stated in the JTR Jewelry Reports that the carat value is based on the manufacturer's declaration.
Research and development activities continue on technologies that will enable the automatic calculation of carat weights in complex jewellery at the JTR Jewelry Technologies Research Center.
JTR Jewellery Reports classifies the colour of diamonds on jewellery in the range of Exceptional white+ (D) colour to Tinted Color (M-Z) colours as specified in the international standards organization (ISO) 24016 standards and the International Diamond Council (IDC) rule book. Diamond colour ranges are used to define the colours of the diamonds on the jewellery.
There are two main reasons for the formation of color in diamonds. These are the secondary elements that have entered the lattice structure of the diamond and the deformation in the lattice structure. The color saturation of the diamonds increases with the increase in the amount of secondary elements. In addition to the secondary elements, as the distance traveled by the light within the diamond increases, the diamonds display more saturated colors.
The reason for using colour ranges is that the analysis of the jewellery covers more than one diamond and therefore the results are stated in groups.
In the analysis of the diamonds on the jewellery carried out with colour reference stones, it is often not possible to determine the colour subgroups to which the colours of the diamonds correspond, due to the materials used around them. Therefore, the colour ranges corresponding to the diamonds are used for colour classification.
JTR Jewelry Reports performs the clarity analysis of diamonds on jewellery within the framework of International Standards Organization (ISO) 24016 standard and International Diamond Council (IDC) rules. In this context, clarity classes are defined between LC and P.
The clarity of diamonds is determined by a correlation of the size, type, number, position, brilliance and mirror images of the inclusions they contain. Reducing the number of inclusions, reducing their size, moving away from the centre of the diamond, and decreasing their contrast and lack of reflections positively affect the clarity and increase the rarity of the diamonds.
In JTR Jewellery Reports, clarity groups are defined as LC-VVS, VS, SI and P. Since the analyzes are applied to more than one diamond in JTR Jewelry reports, it may be necessary to use clarity groups. Within a group, more than one clarity group is defined by the pareo rule.
Diamond groups are a variable grouping system that improves the precision of jewelery reports and enables the value of a jewel to be calculated. Thanks to the grouping system, the size, cut shape, color and clarity of the diamonds are grouped. In this way, diamonds with different qualities are clearly defined in JTR jewelry reports.
As jewels get more complex, the number of groups needed may increase. For this reason, while there are 2 groups in JTR Mini Jewellery reports, JTR Large Jewellery Reports are used for products that require higher resolution analysis and supports up to 4 groups. Jewellery Cards are the compact version of JTR Jewellery Reports. Simple and practical. Jewellery Cards can only contain one diamond group.
JTR Jewelry Reports utilize advanced technologies for material analysis. The metals from which the jewellery is produced are detected using X-Ray Fluorescence Spectroscopy (XRF) and Raman Spectroscopy. For articles made of gold, platinum and silver, the purity of the metals used is also indicated.
Various coatings are used in the production of jewellery. Rhodium plating, gold plating on silver, titanium nitride plating are the platings that are frequently seen in jewellery production. If coatings that affect product value are used on article, these coatings are clearly indicated in the JTR Jewellery Reports. In jewellery production, quality wood materials and jewellery on glass surfaces are produced, albeit rarely. When materials requiring such qualified analysis are encountered, Raman Spectroscopy is used and if this method is not sufficient, JTR Jewellery Report is not produced for the jewellery.

Be sure of the value of your diamond or jewellery with one of the most secure grading report on the market
JTR takes a comprehensive approach in anti-counterfeiting and anti-fraud technologies. By combining both with the best-quality materials, we offer you the most secure grading report.
JTR Reports provide security measures against subsequent changes to the information declared on report with Micro Text.
The hologram used in JTR Reports responds to light of a latent wavelength. This radiation can only be measured spectrometrically, making it impossible to copy.
JTR Reports are secured with special markings that can only be seen under Ultraviolet light.
QRCODE used in reports allows you to connect to JTR servers and confirm that the information on the report is served by JTR. View sample
