The differences

NATURAL

Shape
A diamond is a natural mineral consisting essentially of pure carbon crystallised with a cubic structure
Colour
During formation, natural diamonds were subjected to high temperatures for hundreds of millions of years

The differences

SYNTHETIC

Shape
Synthetic diamonds have the same chemical and physical properties as natural diamonds, but have different growth structures
Colour
A synthetic diamond has been either partially or wholly crystallised or re-crystallised artificially in a laboratory

Diamond businesses must be proactive in managing the risks related to undisclosed synthetics, And that’s exactly what we’re doing.

Through producing cutting edge technology

In 2015, De Beers opened the world’s most sophisticated diamond grading lab in Surat, India, which has the capacity to annually process more than US$500 million worth of diamonds. Its main purpose, initially, was to operate an accurate and reliable grading service for Forevermark diamonds, but since then it has expanded to offer a number of new services to meet the challenges of tomorrow, including the evolving detection of synthetics, simulants and treatments.

IIDGR instruments

Run by the world’s top diamond experts, the IIDGR offer a range of expert services and specialises in the development of industry-leading verification instruments.

The current suite of instruments, including DiamondSure, DiamondSure Mount, DiamondView, DiamondPlus and the Automated Melee Screening (AMS) device, together remain the most robust and reliable in the industry.

The AMS was first launched in June 2014 and is the result of years of technological innovation and investment. It screens near-colourless and colourless round brilliant diamonds from 0.01 to 0.20 carats to determine whether or not they are natural.

PhosView™

In September 2016, a new instrument, PhosView, was launched – a compact, self-contained screening device designed to allow parcels of polished stones to be quickly analysed to determine if they contain potential synthetics, simulants or treated diamonds.

Our investments in the development of innovative diamond technologies enable us to support the industry in addressing some of its major challenges.
