GemLab’s appraisals and lab reports are recognized and respected worldwide by retailers, jewelers, wholesalers, insurance companies, and law enforcement – and by consumers just like you, who need the most accurate and reliable appraisal available in the industry.
Gemstone Identification Reports are requested for standard identification and verification of diamonds and colored stones. This report will include the species of the material, detailed measurements, quality, weight, along with a detailed photograph of the gemstone in questions.
Everything included in the Gemstone Identification Report, with the addition of the region of geographic origination. Tests are conducted to determine where the material was formed and mined from. (Ceylon, Burma, Brazil…etc.)
A diamond report will cover all four C’s: cut, color, clarity, and carat weight. In depth measurements of the proportions are noted, along with a detailed mapping of the inclusions, which will give a complete visual of the internal characteristics, which is useful for identification purposes.
Pearls are unique and have a completely different set of grading parameters, compared to a diamond or colored stone. Details that are only specific to pearls, such as: luster, overtone, and surface characteristics are key points which influence the value of pearls.
A Sarin report is an incredibly detailed listing of individual facet, depth, and table measurements and angles, all required when planning and re-cutting a diamond, customizing a mounting to very strict parameters, or determining ideal proportions, such as “Hearts & Arrows.”
With technology rapidly advancing everyday, the likelihood of undisclosed treatments which enhance the appearance of a gemstone occurs more frequently than ever before. This is a significant factor when evaluating or buying a gemstone at the right price. A natural, untreated blue sapphire is much rarer and more valuable than a blue sapphire with a similar appearance that has been treated.
Determining a natural gemstone that has been created by Mother Nature, from a synthetic (lab created) gemstone, can be tricky and requires special testing. With rapid advancements in technology, differentiating a man-made gemstone that is both chemically and optically identical to its natural counterpart is becoming increasingly difficult to detect without sophisticated equipment and ongoing education and training of these advancements.
