Aureline

Stones cut to answer the light in your room, and delivered with the signature we measured for each one.

Every stone, cut to answer the light in the room

The Aureline cut is the house geometry: 71 facets, angled to return fire at conversational distance rather than only under a jeweller’s loupe. It is cut by hand, in Guwahati, to a tolerance the eye can read across a table.

No two stones behave alike, so we measure each one for light return, fire and scintillation, then deliver it with that signature recorded.

Move across a piece. The gold and the stone answer, with the same return of fire you would read at arm's length, across a room.

All pieces

Radiance · solitaires & bridal

One stone. A raised basket. Nothing in the way of the light.

Radiance is built around the single stone. Every centre diamond is cut in-house to the full 71-facet Aureline cut and paired with its measured light signature, so the ring is chosen for how it behaves at arm's length, across a table or by lamplight, not for a figure on a certificate.

Radiance Solitaire Ring, a brilliant diamond solitaire in a raised platinum basket

Modelled in wax, finished entirely by hand

The Guwahati workshop keeps its cutting, setting and polishing under one roof. A high-jewellery piece begins as a wax on the bench and can take the better part of a year. Joints are filed by hand so a wing shivers; galleries are pierced so light reaches the pavilion.

Nothing leaves until its light signature is recorded under three standard conditions.

A certificate says what a stone is. The signature says what it does.

Each piece is delivered with its own measured card: light return, fire and scintillation, recorded under daylight, gallery light and lamplight. It is how the house asks you to choose.

Every viewing is private and unhurried. Bring a piece you already wear; the light in the room is the only test that matters.
