Introduction
A diamond is a mineral; it forms and grows under natural geological processes.

The jewellery industry relies upon product integrity and transparency for consumers to have confidence

in the products that they are buying. Consumers will not always have the technical expertise to

understand the exact provenance and processing of a diamond and as a result, are reliant upon labelling

and product descriptions as well as guidance from the individual seller.

The recent development of new technologies in the diamond industry has provided consumers with

greater availability of synthetic diamonds which are produced in a factory or laboratory (see 2.4 NOTE 3).

They have essentially the same chemical composition and physical (including optical) properties as a

diamond and essentially the same crystal structure but due to the growth environment, differences in

the growth structure take place at the atomic level.

A major concern held by the diamond industry is that without clear and accurate labelling, the increased

availability of synthetic diamonds to consumers can cause confusion over exactly what type of product is

being sold to them. While the provenance and labelling of a diamond is widely understood, the consumer

will be less familiar with the variety of terms that have been used by sellers to describe synthetic dia
