| 1 | BIS has already formulated standard IS 15766 (Part 1 & 2) for Grading of polished diamonds which is for grading of loose diamonds. However, the diamonds are largely purchased by the consumer in a condition where they are already mounted on a jewellery. It was thus felt necessary to formulate a standard specifying grading of cut and polished diamond, mounted in jewellery. | |
| 2 | The purpose of this document is to specify the minimum requirements which a laboratory shall comply with and demonstrate its competency to carry out identification and grading of diamonds when mounted in jewellery, along with their disclosure in consistent and clear terms. | |
