Diyalbhai Vaghani

It is with this knowledge that I entered the diamond business, after leaving my job in content, around 40 years ago. My fascination for these precious stones gave me the impetus to not only make a drastic career change, but also have a singular dream about making a mark in this highly competitive industry.

Over the years I have always strived to work with integrity, dedication and modesty. I count myself very lucky and grateful to have found a devoted team of colleagues who believe in the same.

The journey to success has indeed been challenging. However, with an enthusiastic team, timely foresight and innovative strategies, Kapu Gems has been able to stay strong and have a distinct brand value; even in the face of recession.

We cater to a wide network of clients from all over the world, including diamond wholesalers, jewellery manufacturers, retailers and designer boutiques. Our main goal is to provide all our customers with the highest quality and best designs in premium diamonds.
I welcome all our stakeholders to be a part of our dazzling future.

‘Diamonds are trumps in the game of hearts.’
