A name you can trust.


Founded in 2018, Lumex, is a Baron Dilip Mehta family venture and is headquartered in Dubai, UAE. An integrated player in the Lab Grown Diamond Industry, the genesis of Lumex began when Dilip Mehta visited a lab grown rough diamond producer in 2018. On learning more about the production process and seeing the resulting product, it was clear that a lab grown diamond is novel yet accessible, aspirational yet acquirable for customers.

Lumex was incorporated shortly thereafter and builds on the family legacy of 100+ years of experience in the natural diamond industry. Having been key drivers of their original family business, Dilip Mehta and his son Vishal Mehta have been applying their network and operational expertise to formulate a unique niche in the lab grown diamond space.

Dilip Mehta

Dilip Mehta is a trusted and leading name in the Global Diamond Industry. He was CEO of his family business, Rosy Blue, one of the largest companies in the natural diamond industry, between 1973-2007 and was integral in building the company to a USD 2 Billion business. He continues to remain a strategic investor in Rosy Blue and play a senior advisory role which is completely independent of his involvement in Lumex.

He is the only diamond businessman to be awarded the title of a Baron by the King of the Belgium for his contribution to Belgian businesses. Dilip Mehta's time as CEO of Rosy Blue was marked with great success. He was integral in transforming Rosy Blue from a manufacturing/trading office to a global marketer of a broad range of products and services. This resulted in sales, manufacturing and financing offices in 13 countries spanning 4 continents: Armenia, Belgium, China, Hong Kong, Israel, Japan, Luxembourg, Russia, South Africa, Sri Lanka, Thailand, United Arab Emirates and the United States of America.

Dilip Mehta oversees the Lumex business and advises his son, Vishal Mehta on the day to day aspects of the business. He has been pivotal in setting up Lumex’s sourcing and distribution networks.

Vishal has brought the same rough sourcing and operational expertise to the Lumex business and looks forward to leveraging his past experience for the benefit of THE FUTURE.
