Quai du Mont-Blanc
private salon by appointment
ASTERIA has spent four generations looking for colour that does not exist anywhere else — a ruby that glows in the dark of a pocket, a sapphire the blue of a Geneva winter, an emerald with its whole garden still inside.
Jewels that carry
more colour than
the room they
walk into.
Black and white everywhere — so the stones can do the shouting.
Since 1897 the Maison has bought fewer than one in a thousand stones it is shown. Each is cut, set and polished in our Geneva atelier by thirty-eight hands that sign their work.
We make no editions and no copies. When a piece leaves the salon, its drawing is archived and never used again.
The five
stones
We work with only five families of gems — and only with the finest of each. Hover a stone to see it.
In
numbers
A century and a quarter of colour, counted the way our gemmologists count it.

Every coloured stone above one carat travels with a report from the SSEF or Gübelin, and every diamond with a GIA certificate. Copies are archived at the Maison forever.
