Stones chosen for range. Assessed for the right reasons.

We stock certified diamonds, coloured gemstones, and gold jewellery — each piece selected against standards particular to Eastern India's crafting traditions, not a national catalogue.

— Three Distinct Categories

Gold Jewellery

22- and 18-karat gold pieces spanning necklaces, bangles, and sets. Hallmarked and sourced from Bengal's regional crafting centres where the finishing standards remain exacting.

Certified Diamonds

Round brilliants, princess, and fancy cuts — each stone graded for cut, colour, clarity, and carat weight. We carry certificates and explain what each number means before you decide.

Coloured Gemstones

Rubies, sapphires, emeralds, and spinels assessed for saturation, clarity, and origin. We do not stock stones that look right under showroom light but read differently at home.

▸ Eastern India Standard

Kolkata's ambient light — diffuse, warm, high-humidity — affects how a stone reads in daily wear. We evaluate colour and brilliance under conditions that match where the piece will actually live.

How we assess every stone

Every inventory decision is made against that single criterion. A stone that performs under a dealer's halogen but fades in Bengal's light does not reach our cases.
