LGIC is a non-profitable institute which has long been devoted to the research of lab grown gemstones and the elaboration of inspection standards.
The lab grown gemstone can be traced back to more than 100 years ago, when the French chemist Verneuil invented the flamefusion process (i.e. Verneuil Process). This process is mainly used to grow corundum like ruby and sapphire, as well as imitation diamonds like rutile and strontium titanate.
In this industry there are around 10 popular techniques to grow gemstones, like hydrothermal method, flux method, Cz method, KY method etc. The gemstones grown from these different techniques vary in quality and the market recognition.
LGIC intends to help developing healthily the lab grown gemstones by setting up a scientific classification. LGIC’s classification on lab grown gemstones refers to the classifying method of natural gemstones used by various gemstone research institutes.
LGIC is a non-profitable institute.They has carried out scientific analysis and grading of the Articles referred to in this Report, utilizing advanced and up-to-date gemological instruments and equipment available at the time of examination. Evidence of known treatments, simulants and synthetics are detected and disclosed. However, technologies employed in treatments, processing and synthetics are continuously evolving, hence it might not always be possible to determine the origin of the article using the then-latest available techniques.
1. The identification results are only responsible for the samples submitted for inspection. Reprinting, copying and alteration are invalid.
2.The Jewelry Report is based on the gemological analysis of the Article, but also on data or documentation occasionally supplied therewith. Accompanying reports and hallmarks are accepted as factual, with the implicit understanding that LGIC does not guarantee, nor warranty their accuracy. Characteristics, weights and measurements are approximate when analyzed in mounted conditions.
3. Gemstones are sometimes enhanced or treated in order to improve their appearance. These processes, including synthetics, are not always identifiable in mounted conditions.
4.This appraisal report does not serve as an investment recommendation. Neither the Client nor any purchaser of the articles shall regard this Report as an appraisal or as a guaranty or warranty. In the event of any claim by the Client or any person for damage to the articles, or damages resulting, directly or indirectly from this Report, the liability of LGIC shall be limited to the amount it receives as a fee in connection with this Report.
5.Opinions may vary as to the characteristics covered in this Report, and results of the examination performed on the diamond may differ depending by whom, when and how the diamond is examined; hence, neither LGIC nor any member of its staff shall, at any time, be held responsible for any discrepancy which may result from the application of other grading and/or identification methods.
LGIC operates as an independent laboratory, its staff is not subject to internal and external, improper commercial, financial and other pressures and influences, and is not affected by various aspects of economic interests, to ensure the authenticity, objectivity, accuracy and traceability of test data and results.
