About Us
A legacy of excellence in Diamond Craftsmanship
The story of The Diamond Store by Chandubhai begins with a family deeply rooted in jewellery making. Chandraprakash, known to many as Chandubhai, represents the second generation in this craft. He became the first Hallmark certified gold manufacturer in the country, which set the foundation for a brand built on trust and skill.
In 2009, Chandubhai and his son Kotti Srikanth founded Hallmark Jewellers. Their shared vision combined traditional workmanship and modern design. The Diamond Store by Chandubhai took shape in 2017 as a dedicated space for fine diamond jewellery. Today we are known for originality, responsible sourcing and a style that blends art with precision.

Milestones
One of the most significant achievements in our journey is the creation of “The Divine 7801 Brahma Vajra Kamalam,” a ring set with 7801 natural diamonds.
