About our company

The origin of IrisGem/ Instituto de Monocristales dates back to 2001.

A high-tech company, dedicated to R&D activities and based in Spain, which was founded with the ambitious goal of developing a new process for creating Lab grown diamonds following the same process as nature does: Carbon crystallization under high pressure and high temperature.(HPHT)

The development of this and other necessary processes to ensure the treatment of the carbon source, origin of the diamond, growth, quality and color, obtained the expected success and lead to worldwide leading technology to produce Lab Grown diamonds for Gem- and scientific application.

The company possesses under the name of Irisgem market knowledge and sales in several countries (direct and through distributors) mainly for Bio-diamonds, but also for Gem diamonds.

After being patented in September 2005, marketing of bio-diamonds begins, according to our philosophy of innovation, developing new technology and new processes to create human and environmentally sustainable diamonds.
