Our Policy on 

Ethical Diamonds

There is a growing consumer awareness about conflict diamonds as well as alternatives to natural diamonds such as laboratory grown diamonds.

Jeremy France Jewellers only sources its diamonds and gemstones from reputable companies who also comply with the Kimberley Process.


Kimberly Process

“Conflict diamonds” (also known as “blood diamonds”) are rough diamonds that have been mined in parts of the world where civil wars and conflicts are taking place. Rebel groups illegally sell these diamonds to fund wars against their governments.

In January 2003, a force comprising the United Nations, 52 world governments and the diamond industry decided to try and put an end to this illegal trade. They formed the Kimberley Process.

The Kimberley Process basically means that imported and exported diamonds are sealed and certified during their travels, so that conflict diamonds cannot enter the supply chain and means that any given parcel is traceable.

The introduction of the Kimberley Process has meant that conflict diamonds have decreased from 4% in 1990, to less than 1% of the world’s diamond supply today, and 82 international governments are signed up to the process.

We at Jeremy France Jewellers use well-established suppliers who have signed their confirmation that the diamonds they provide to us are from conflict free sources, so that our customers can shop with confidence.


Grown Diamonds and Diamond Simulants

We are seeing a growing interest in laboratory grown diamonds as an alternative to natural, mined diamonds. Natural diamonds, by their definition, were naturally formed through heat and pressure in the Earth’s crust, and a diamond simply referred to as “diamond” should always be a naturally created stone. All our diamonds stated as “diamond” on our receipts and online are natural diamonds and not laboratory grown.

A synthetic diamond is an artificial product that has essentially the same physical characteristics as a diamond, and is created by imitating similar heat and pressure conditions to those in which natural diamonds form. All laboratory grown diamonds are therefore synthetic diamonds.

An imitation diamond, also known as a diamond simulant, is usually an artificial product that imitates the appearance of a diamond without having the same chemical composition, physical properties or structure. We do sell some imitation diamonds, which are clearly labelled as CZ (cubic zirconia) in store and online.

These stones are not as strong as diamonds, and their sparkle, although lovely at a glance, does not have the complexity and depth of a diamond. However, their low cost makes them ideal to enjoy in silver and fashion jewellery. As long as you are fully aware that you are not purchasing a natural diamond, you can enjoy the added sparkle a CZ or other simulant stone will bring to your jewellery.

We have made the decision to currently not stock synthetic, laboratory grown diamonds in store. We do have contacts from whom we can source these if required for bespoke requests. We are happy to discuss the pros and cons of laboratory grown diamonds in store if you wish to consider these.

When purchasing second hand jewellery from customers for our pre owned window, all customers must sign documentation to confirm that all diamonds within the piece are natural and not laboratory grown. Along with certification checks on larger stones, this ensures we are doing everything within our power to make the origins of our diamonds clear to our customers, and prevent synthetic or stimulant diamonds being mis-sold.
