Gemstone Grading

The jewellery industry has yet to standardise a consistent scale for Gemstone Grading. Though there are several testing agencies that provide detailed gem grading reports they fall short when it comes to classifying levels.

Reports, which are limited to colour and stone grading, are not as systematic, methodical and detailed as a diamond grading report, and they vary significantly from agency to agency.

With gemstones it is mostly about the colour and geography in determining quality and value.

However, gemstones should have trusted supply origins to ensure that it is known exactly where they are coming from and that mining, cutting, and polishing have all been carried out under ethical standards.

All Henry Aston gemstones are ethically sourced through London Diamond Bourse members following strict supply guidelines and each one is personally selected for your item of jewellery by us.
