After shifting our production from Thailand in 2013, we established our business and manufacturing in India as Stepin Diamond Private Limited. Supported by a team with over thirty years of experience in the natural diamond industry, we strive to adhere to the dignified approach of conducting business even today. By sourcing our rough diamonds in the utmost ethical manner and polishing our diamonds meticulously, we have been able to extend our supply to niche jewelers all over the world. We ensure that all rough diamonds purchased by our team are certified by the Kimberly Process.


Stepin operates based on a core philosophy deemed as the “Three Pillars”:

  2. Quality over Quantity: We are always striving to ensure that by providing top makes and finishes for both rounds and fancy shapes, our diamonds yield eternally valued beauty.
  3. Transparency: Internally and externally, we value honesty and building trust throughout our supply chain.


As a vertically integrated organization, we choose to serve at every touch point throughout the value chain.
