Our Story
Primestar’s journey began in the early 1990s when its founders, Raj Kothari and Priti Parikh, moved to Antwerp, Belgium, the heart of the global diamond trade.
Early on, Raj established a strong reputation in the industry, specializing in supplying diamonds to luxury brands. He adopted a customer centric approach grounded in honesty, consistency in quality and a high level of service. Meanwhile, Priti devoted herself to raising their children, instilling in them core values such as integrity, accountability, and trust to help them make a positive impact on the world. She noticed the industry was male dominated and her unique perspective as a woman and a consumer would add value across the supply chain.
With this vision, Priti set out to build a sustainable diamond business for the future, leveraging Raj’s expertise and deep-rooted relationships. In 2016, Priti became a HRD-certified gemmologist and Primestar was born.
