    INFORMATION QUESTIONS

    FREQUENTLY ASKED QUESTIONS

    Q1. How many types of diamond grading reports are issued by ACGS?

    Ans. For diamonds in near colorless range, ACGS issues the following three types of reports – a) Diamond Grading Report – all relevant particulars and parameters of the stone along with a plot diagram of the crown and the pavilion view. b) Diamond Summary – all essential and important particulars are recorded, but without a plot diagram. c) Card Report – carries only the essential information and the grade, without a plot diagram.

    Q2. What kind of standards are adopted in issuing diamond grading reports at ACGS?

    Ans. Grading of diamonds at ACGS is carried out in accordance with standards and norms followed by the GIA. Reports issued by ACGS also keep in view the standards laid down by the Indian Standards Institute (ISI).

    Q 3. What happens if the grading report issued by ACGS does not match with report issued by another laboratory in respect of the same stone?

    Ans. Observation and judgment are involved in grading diamonds. It is, therefore, possible that there may be a slight difference in reports issued by two different laboratories in respect of clarity or color grades. ACGS carries out a recheck of its own report by charging a nominal fee on the request of the client.  

    Q4. Does ACGS lab undertake grading of fancy color diamonds?

    Ans. Yes. Fancy color diamonds are graded for clarity and color in line with norms adopted by the GIA laboratory.

    Q 5. What if I submit a solitaire mounted in a ring or a pendant for grading? Is the grading as accurate as in the case of a loose diamond?

    Ans. Accuracy in grading a diamond, whether near colorless or a fancy color, is limited to an extent if it is mounted. Certain features are hidden by metal work and can not be observed by the grader. For this reason, GIA laboratory does not, as a rule, accept any diamond for grading, unless it is submitted as a loose stone. However, ACGS accepts mounted diamonds for grading, and the report is always subject to limitations imposed by its setting.
