Terms and Conditions - Important Limitations
- IDL' certificates describe the characteristics of the diamond(s), jewel(s) or the gemstone(s) after they have been examined using specialised equipment and instruments including binocular microscopes, 10x magnification loupe, optical measuring devices and other instruments and processed as deemed appropriate and allowed by the design and the material of the jewel, and 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 using the then-latest available techniques. A Jewelry Certificate is based on the gemological analysis of the Jewellery as mounting permits . Characteristics, weights and measurements are approximate when analyzed in mounted conditions. IDL does not guarantee nor warranty their accuracy. Possible enhancements may not be disclosed. Gemstones are sometimes enhanced or treated in order to improve their appearance. These processes, including synthetics, are not always identifiable in mounted conditions.
- IDL' certificates are not a guarantee, valuation or appraisal of the diamond(s), jewel(s) or gemstone(s) but an assessment and opinion of the materials and there qualities at the moment of examination and as can by detriment by current and available methods and procedures. Opinions may vary as to the characteristics covered in the certificates, and results of the examination performed on the diamond, jewel or gemstone may differ depending by whom, when and how the diamond, jewel or gemstone is examined; hence, neither IDL 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. By making the certificate IDL does not agree to purchase or replace the diamond(s), gemstone(s) or jewel.
- In the event of any claim by the customer or any person for damage to the diamond(s), gemstone(s) or jewel or damages resulting, directly or indirectly from the certificate, the liability of IDL shall be limited to the amount it receives as a fee in connection with the certificate.
understanding the 4 C’s of Diamond Jewelry
Carat weight of the stones set in a jewelry is estimated as an approximate weight according to formulas taking into consideration the measurements of the stones. Only when a diamond certificate is available, an exact weight will be mentioned in the jewelry certificate.
In principle for jewelry, color will not be graded in detailed grades as for loose diamonds (Ex. D) but in ranges of 1 up to 3 color grades ( Ex. range D, range D-E, range D-E-F). Exact color (Ex. D) will only be given if the stone has a diamond certificate.
In principle for jewelry, clarity will be graded not in detailed grades as for loose diamonds but in broader grades (Ex. VVS, VS, SI, and I) or even in ranges of these clarities (Ex. VVS-VS, VS-SI). Exact clarity (Ex. IF, VVS1, VS) will only be given if the stone has a diamond certificate.
Cut will be described with one overall grade including proportions and finish. (Ex. excellent, very good, good, poor, fair).
The 4C's of Diamond Jewelry are determined as mounting permits.
