From the Mine to the Trade

TT Diamonds is a diamond trader with its own mines and diamond cutting shop.

Our Diamond Mines

The pictures show our own diamond mines in the Central African Republic - Berberati and from South Africa - Kimberly.

For more than 25 years, diamonds have been mined here for TT Diamonds customers in accordance with the high ethical principles of the international diamond industry.

Our diamond grinding shop

We process rough diamonds of all types and sizes in our in-house diamond grinding shop.

We have been grinding for more than 40 years and have professional equipment at our disposal. With our computer-aided analysis software we can analyse diamonds exactly and calculate sizes and values.

Ethical principles & transparency

We are committed to ensuring complete transparency for our customers.

For us, this means providing open and transparent information about all materials and products that we use, process or offer, as well as our working practices.

When using the various diamonds it is also our concern to inform our customers in detail about their quality, processing method, artificial changes as well as their origin.

As a consequence, we continuously promote the training and further education of our employees. We respect and support the high ethical principles of the international diamond industry. We apply the rules of the Kimberley Process and the World Diamond Council.

We only offer diamonds from legitimate sources that are not involved in conflict financing. Furthermore, we apply the rules of the international trade organisation "CIBJO" (The World Jewellery Confederation) in the field of gemstone declaration and do not violate standards regarding environmental protection, child labour and health care.
