Our Story
Diamond House began in 1979 as a small jewellery showroom on Jotiba Road, Kolhapur — built by Prasad Kolhapure's instinct for stones and a refusal to sell anything he wouldn't wear himself. Today, his daughter Aakanksha, a trained gemmologist, has added what the family always wanted: a proper in-house gemmological laboratory.
Two names. One promise.
Prasad Kolhapure
Founder
Four decades in the trade. The hand that picks the rough, negotiates the cut, and signs off on every finished piece. If a stone makes it into the showroom, it's because Prasad said yes.
Aakanksha Kolhapure
Gemmologist · Lab Director
Professional gemmologist, second generation. Runs the lab at 607 Krystal Square, Nagala Park, Kolhapur — refractive index, specific gravity, microscopic inclusions, treatment detection. Every identification report carries her signature because she personally examined the stone.
What sets us apart
Founded as a family jewellery house in Kolhapur, we've spent four decades earning the trust of families across Maharashtra — one stone, one piece, one customer at a time.
Aakanksha Kolhapure is a professional gemmologist who personally examines every stone. Every identification report is signed by a human — never by a machine alone.
Refractometer, polariscope, microscope, specific-gravity testing — the same equipment used by international labs, here at our facility at 607 Krystal Square, Nagala Park, Kolhapur.
Every diamond, gemstone and finished piece is graded, photographed and issued a identification report you can verify by QR code — anywhere in the world.
Come meet us in person.
Two showrooms in Kolhapur, one in Pune. Tea is on the house — stones are on the tray.
