FOUR DECADES OF DIAMOND AND JEWELLERY EXPERTISE

Second Generation Mastery & An Unrivaled Eye

  • The Foundation

    Founded on a legacy over forty years ago in the bustling heart of the early diamond trade, ATC began with a singular focus: the human ‘Eye’. Long before laser mapping and digital colorimeters, our reputation was built on an innate, uncompromising ability to judge the true character and life of a stone—factors a machine cannot easily quantify.

  • The BDB Era

    As the trade shifted, we established our stronghold in the prestigious Bharat Diamond Bourse in Mumbai. As a second-generation firm, we bridged the gap between old-world craftsmanship and global scale. We began curating specialized parcels for US & European high-jewellery, ensuring every assortment met the rigorous, unseen standards of Place Vendôme and of US Chain Stores.

  • The Future Shield

    Today, we combine our forty years of grading mastery with state-of-the-art blockchain transparency. We specialize in Maison-grade stones that possess both exceptional beauty and an unassailable, documented provenance. Our heritage is not just our history; it is your brand’s ultimate assurance of unmatched quality and trust in a highly regulated future.

    Adding to this our company is striving to become RJC COP certified soon to bring confidence to all customers about the processes we follow are as per the highest industry standards
