Our Services



Luminas is headquartered in Antwerp, with its affiliate companies situated in Mumbai, Hong Kong (and Israel).

A relatively young company established in 2007, Luminas does however inculcate the knowledge and experience of three generations of diamantaires.

Originally engaged in the business of coloured stones, our family diversified into diamonds in the mid-1970s.

Production and service


Our company was formed at around the same time that the diamond industry was experiencing a major upheaval, both in terms of its functioning as well as its increasing dependence on external economic forces, from which we were cushioned up to that time.

In fact, the last decade has seen a radical shift in how the diamond business is run globally.

We are now as much a service industry, as we are a manufacturing driven one. Service is as important as the product.

Professional passion


With the industry evolving rapidly, and the modern challenges facing today’s diamond dealers, this necessitates a change in the way business is conducted today.

With a young management team, we pride ourselves in being in touch with the needs of the market and our ability to adapt.

We strive to provide you with the drive and passion of a family-run business operation, with the efficiency and competence of a professional enterprise.

Conflict free guarantee

We are a member of the Diamantclub in Antwerp, which is part of the WFDB (World Federation of Diamond Bourses).

All members cooperate and work in mutual trust with the requirement that the sources from where diamonds (rough and polished) have been originally purchased are legitimate, are not involved in funding any conflict and are in compliance with United Nations resolutions. 

We guarantee you in writing on our invoices that all our diamonds are conflict free, based on our personal knowledge and/or written guarantees provided by the supplier of these diamonds.


Rays of inspiration

 Not like any other mineral.

The refractionrate of the mineral determents the amount of light it can return through mirroring at its inner walls.

Only diamond can let the light reach our eye.
