The Patan Atelier · Kathmandu Valley

One roof in Lalitpur.
Cut, certified, and shipped — here.

A 46-year gemstone house where rough Himalaya enters as stone and leaves, six to ten weeks later, as a signed, GIA-numbered aquamarine with a paper trail.

Est. 1978  ·  Patan Dhoka Marg, Ward 8

Chapter One · The Founder

A bench in Patan, a brass loupe, and a single apprentice.

Hari Bhattarai opened a one-room lapidary on Patan Dhoka Marg in the spring of 1978, the year Kathmandu's first paved ring road was finished. He had learned to cleave tourmaline from his uncle in the old bazaar and had saved for nine years to buy a secondhand faceting machine shipped overland from Idar-Oberstein. For the first decade the workshop cut what the local trade brought him: smoky quartz, pale citrine, the occasional blue topaz that passed for aquamarine on a Jaipur buyer's table.

What changed the house was a single, unusually clean aquamarine crystal pulled from a riverbed in the Ganesh Himal range in 1991. Hari cut it in a slow emerald step, kept it for two years, and sold it, through a chain of four brokers, to a Belgian dealer for fourteen times his usual margin. He understood, then, that the stone was not the product — the path was.

Forty-six years later, the workshop on Patan Dhoka Marg is still in the family. Hari's son, Anish, runs the floor. His daughter, Purna, manages certification. The bench where he taught himself to read a crystal's grain is now bolted to the wall behind a glass case, used as a teaching prop for the three GIA Graduate Gemologists on staff. The house has never raised outside capital and has never sold through a third-party retailer.

The Bench

Three GIA gemologists. One master cutter. One roof.

The only GIA-trained lapidary team in Nepal. Every stone in the catalog passes through at least two of their hands before it is sealed into a parcel.

Vertical Integration

From a Ganesh-Himal riverbed to a signed certificate — one roof.

Most aquamarines change hands four to six times between mine and buyer. Ours change hands once. That is the entire price advantage.

  1. Rough aquamarine crystals received at the Patan workshop intake bench

    Stage One

    Rough intake & provenance

    Each crystal arrives with a mine tag naming the river valley and the date it left the ground. Rajan logs weight, crystal habit, and visible inclusions against the house's 1978-vintage grading ledger. Stones that cannot be traced to a named Himalayan source are returned to the supplier. Roughly one in eight parcels fails this step.

  2. A cutter shaping a faceted aquamarine against a wet diamond lap

    Stage Two

    Planning & hand-cutting

    Before any diamond touches the stone, Anish plots the cut on a Sarin report to protect color and minimize weight loss. Most aquamarines from the house leave the bench as emerald cuts, step cushions, or elongated ovals — shapes chosen to keep the gem's natural cool blue rather than to chase maximum yield.

  3. A finished aquamarine beside a grading loupe and a draft certificate

    Stage Three

    Polishing & pre-certification

    After final polish, each stone is weighed, measured, and graded in-house against GIA's Colored Stone Grading System. Stones that do not meet the catalog's minimum clarity and color standards are sent to Mira's recovery floor for re-cut or cabochon conversion — over 800 rough pieces pass through that workshop every month.

  4. A finished aquamarine in its velvet box with certificate and provenance map

    Stage Four

    Certification & shipment

    Every stone over one carat ships with a signed Certificate of Authenticity, a provenance map naming the source valley, and the lapidary who cut it. Parcels leave Kathmandu twice a week, insured, to customers in 67 countries — most arriving within five business days of dispatch.

Provenance Promise

“A gemstone with no paper trail is a story half-told. We sign every certificate because a buyer's daughter should be able to ask, forty years from now, exactly which mountain her mother's stone came from — and we should still have the answer.”
