In the process of applying standards to jewellery, hallmarking is a highly essential practice. Hallmarks, which are small markings made on jewellery made of precious metals like gold, silver and platinum, denote the true measures of purity of each piece. It’s informative as to the amount of the precious metal present in each piece and certain other properties. It’s also the stamp of trust and true value which will not be undermined at any place or time period.

Hallmarking is done by BIS (Bureau of Indian Standards). You will learn in jewelry design classes that this body is involved in a range of activities that are aimed at ensuring that only quality commodities reach the hands of the customers. BIS hallmark technically denotes and includes:

  • The BIS triangular symbol
  • The grade of purity of the metal
  • The assaying and hallmarking centre’s mark
  • Year of the marking in alphabetic code
  • Identification mark of the jeweller

Certification of Diamonds


Diamonds are the other major jewellery category that people buy from. Their quality assessment and certification of purity are done based on their gemological makeup, natural rarity and finished quality. Assessment of a diamond’s quality is determined by its properties namely cut, color, clarity and carat weight. The assessment adheres to international standards. Bodies like IGI (International Gemological Institute), GIA (Gemological Institute of America) and AGS (American Global Standards) can offer expert services to verify and certify the quality of a diamond. 

In fact, the report from any competent certified expert in diamonds can be a valid reason to choose to buy a piece. The importance of trust in dealing with jewellery and precious stones thus creates the need to pitch in the service of competent institutes. Learning more about them can put you in a better place while buying or selling jewellery.
