Certification Guide

A jewellery certificate gives you assurance about the qualities and value of your unique gemstones & gold. Also, it serves as the proof of identity for the jewellery piece you buy. We, at D. Khushalbhai Jewellers, take this very seriously. Before you decide to buy, take a look at the certifications we provide.

What is BIS Hallmark?

The BIS hallmark is a hallmarking system for gold as well as silver jewellery sold in India certifying the purity of the metal. It certifies that the piece of jewellery conforms to a set of standards laid by the Bureau of Indian Standards, the national standards organization of India.

What does a BIS hallmark consist of?

BIS Hallmark for gold items consists of five components or marks. These marks are:

BIS Standard Mark: ISI mark is a mark for industrial products in India. The mark certifies that a product conforms to the Indian Standard(IS), developed by the Bureau of Indian Standards (BIS), the national standards body of India.

Purity Grade: It is the purity of gold indicated in two ways: Karat (denoted as KT) and fineness number. When purity of gold is measured in Karat, 24KT is considered the purest form of gold. But 24KT gold is considered too soft to be converted into any jewellery or ornament. Fineness number is another way of measuring the purity of gold. It is measured in purity in parts per thousand.

Hallmarking Centre’s Mark: The laboratory where gold jewellery is assessed to check its purity is also required to put their logo on the jewellery. Only licensed laboratories of BIS can check the purity of gold. One can check if the hallmarking centre is licensed by BIS or not on their website.

Year of Marking: Alphabets represents the year of hallmarking of jewellery and is decided by BIS e.g. letter ‘A’ Denotes Year 2000, ‘J’ for 2008, ‘N’ for 2011 and ‘P’ for 2012 etc.

Jeweller’s Mark: The jewellery shop from where you are buying your gold jewellery will also put its identification mark. This mark can be of a BIS certified jeweller or jewellery manufacturer.

The IGI Coloured Gemstone report states that the gemstone is naturally generated or synthetic, providing data such as shape, cut, weight, size, color, transparency, and primary optical characteristics, with a clear gemstone photo. If gemological analysis reveals the country of origin of the gem, this information will also be included in the report.

No single component is better than the other and therefore individual preferences will vary. In the overall light performance, the three components are shown separately in the bar graph and then weighted equally to give an overall light performance rating of the light return. Shapes are analysed in comparison to their own, since the maximum achievements levels will vary with each shape.
