Madestones® has grown into a well-established producer and distributor of laboratory-grown diamonds in Europe.
Laboratory grown diamonds are the new trend in diamonds and simply a new kind of diamond. They are not a substitute for natural mined diamonds, but a new and very relevant alternative.

The brand for marketing laboratory grown diamonds with full disclosure and transparency, is an initiative from Thierry Silber, a third generation diamond trader and CEO of Diamaz International, the parent company which is based in Antwerp-Belgium, known as the world diamond capital.

Madestones® are diamonds that are grown in the laboratory and have exactly the same optical, physical and chemical characteristics as mined diamonds. The 3 major international diamond laboratories GIA, HRD and IGI provide diamond grading reports stating that it's a real diamond with the only difference being its point of origin. One is grown above the ground while the other is extracted from the ground.

Mined diamonds are not necessarily always the preferred choice. The popularity of Madestones® is rapidly increasing and is the preferred option for the socially and environmentally conscious consumer. They also appeal to the younger and technologically forward generation. They offer consumers a new and affordable alternative choice to mined diamonds.
Madestones® are a product of modern technology. They marry science to social values. They are eco-friendly, ethical, sustainable and affordable.

They are available in white and beautiful yellow, blue and pink colours. White Madestones® cost around 45-50% cheaper than their natural sisters.  Colour Madestones® prices are spectacular compare to mined diamonds. They now offer the consumer who would like to purchase a beautiful colour diamond a real alternative at a very affordable price.
