Reports & Services
WGI Gemmological Reports intend to describe the characteristics of the article submitted for analysis to the laboratory but also give a valuable and useful tool to the jewellery Industry. The Reports, with their unique online report verification number, may contain results of loose or mounted diamonds or gemstones, features and characteristics of eventual precious metals present in the article analysed.
DIAMOND GRADING REPORT
A diamond report covers the four C’s: cut, colour, clarity, and carat weight. Your diamond report will include an in-depth measurement of the proportions of your diamond, along with a detailed mapping of the inclusions which will give you a complete visual of the internal characteristics, which is useful for identification purposes.
GEMSTONE IDENTIFICATION REPORT
Gemstone Identification Reports are requested for standard identification and verification of diamonds and colored stones. This report Includes; the species of the material, detailed measurements, quality, weight as well as a detailed photograph of the gemstone.
PEARL GRADING REPORT
Pearls are unique and have a completely different set of grading parameters, compared to a diamond or coloured stone. Details that are only specific to pearls, such as: lustre, overtone and surface characteristics are the key points which influence the value of pearls.
VERBAL PRE-GRADE / EVALUATION
If you’re considering investing in a diamond or a piece of jewellery, it is essential to have the piece evaluated to ensure you are getting what you paid for.
We recommend you to have a verbal pre-grade/evaluation done on the item before buying it, so you can rest assured that the item will fulfil your expectations. Our expert team will explain the details of the quality and the value of the item so you have a better understanding of your investment.
NATURAL VERSUS SYNTHETIC (LAB CREATED) VERIFICATION
Determining a natural gemstone that has been created by Mother Nature or a synthetic stone that has been created in a lab is becoming increasingly difficult and requires special testing. Our Gemologists use advanced equipment to test the stones and distinguish if the stone is natural or synthetic.
PROFESSIONAL PHOTOGRAPHY
Capturing the beauty of your investment can be difficult with a regular camera. WGI has a team of professional photographers trained specifically in Jewellery and gemstone photography using advanced equipment. If you need a professional image of your investment for insurance or keepsake purposes, please ask to speak to our professional staff.
SARIN REPORT
A Sarin report is an incredibly detailed report, which shows the cut and symmetry of your diamond. Proportion and symmetry of a diamond are the main factors that determine the amount of light return which gives the diamond its brilliance and sparkle. A Sarin report is required when planning and re-cutting a diamond, customizing a mounting to very strict parameters, or determining ideal proportions, such as “Hearts & Arrows.”
SECURITY SEAL
A security seal is a tamper-proof container in which your diamond is sealed for security with a summary of the diamond report. The security seal is available upon request.
LASER INSCRIPTION
Laser inscriptions are microscopic and cannot be seen to the naked eye. Typically, the lab report number is inscribed on the girdle of the stone for identification purposes, however a personal message can also be inscribed on the girdle upon request.
