Origin of rough diamonds, ethics and transparency: the priorities of our house

History of the business


Maison A. Vernain SA was founded by our grand-father Honoré in 1900 and entered in the Geneva's commercial registry in 1903. Our grandfather, who was destined for a career as a notary public clerk but was not attracted to it, decided to learn the trade of diamond-cutter in a diamond-cutting workshop. He then founded his own diamond-cutting factory in 1900 near the Geneva's train station in the district of Montbrillant.

Our work consists of choosing and buying the finest gems from partners diamond-cutting factories around the world. We then sort, grade, certify and assemble them in order to supply the needs of our clients within the shortest possible time.



How to choose your diamond


The price of a diamond is based on the 4C's rule. Carat for the weight, Cut for the cut finish, polish and symmetry, Color for the hue in diamonds & Clarity for the level of inclusion.

The heavier, colourless, pure and well-cut a diamond is, the higher its price will be.
