History

In 1979, driven by his passion and entrepreneurial vision, Ranjeet Barmecha founded NIRU, establishing a company grounded in kindness, excellence, and sustainable growth. The name “NIRU” is a testament to love and family, named after his wife’s, nickname, serving as a daily reminder of the foundational values that have shaped the organization.

As NIRU’s reputation for precision and quality flourished, so did its family. In 1991, Ranjeet was joined by Micha Aharon, a close friend and expert in baguette-cut diamonds. Together, they elevated NIRU’s craftsmanship, catering to the most prestigious luxury brands. The shared values and collaboration between Ranjeet and Micha strengthened the business and set the stage for NIRU’s expansion.

Today, under the leadership of Ranjeet’s son, Rakesh Barmecha (President of NIRU), alongside Micha’s daughter, Keren Benjo (COO), and Ranjeet’s nephew, Sanjay Baid (Managing Director of the Sri Lanka flagship diamond manufacture), NIRU continues to thrive. This second generation of leadership ensures that the company remains committed to its core values of care, precision, and innovation while upholding its legacy of excellence.
