Our History

Established in 2005, Singapore-based IIa Technologies Pte. Ltd. is an industry leader in grown diamond technology. Based on its patented research, the company grows colourless Type IIa diamonds (the purest type of diamond) through a commercially viable and sustainable process.

IIa Technologies’ Singapore facility powers a technology called Microwave Plasma Chemical Vapour Deposition (MPVCD) which is able to provide an environment suitable for growth while relying on nature to do the rest. Rough diamonds grown by IIa Technologies are used in the commercial sector (mechanical, manufacturing, aerospace industries), scientific and medical instrumentation as well as in the luxury sector.

IIa Technologies was born by a chance meeting in 2003 of Dr Devi Shanker Misra, an expert with several decades of diamond growth experience gained while with the Indian Institute of Technology in Mumbai, and members of the Mehta Family, third generation professionals in the Gems and Jewellery industry. This meeting created a synergy of knowledge, industry experience and financial capabilities that provided the ingredients for IIa Technologies to form its beginnings.

IIa Technologies spent the first six years in Singapore purely on research to perfect their technology. The company has the largest MPCVD diamond research facility in the world. Several challenges faced by IIa in the beginning included the shortage of seeds, the ability to grow only small diamonds and mounting costs for running the facility. The team’s hard work and perseverance paid off when they were able to find a sustainable and effective solution that overcame these challenges.

The three members of the executive team are Dr Devi Shanker Misra, CTO and Executive Board member, Mr. Vishal Mehta, CEO, and Mr. Michael Tan, Executive Director and CFO.
