About us

It took a few years to get right to the source.

We spent many years building mutual trust. We are now where we wanted to be twenty years ago. In a place of equal partners.

We had to prove our passion for emeralds to them a thousand times. We’ve been digging in the bowels of the Cordilleras. We learned to tell the good emeralds from the bad. We fell in love with all the natural anomalies that go with emeralds.

We have come to appreciate the ordinary people who work with emeralds.

Our activity does not end with the sale. We are interested in what happens to the stones afterwards, what jeweller is involved, who wears them, how the chosen stone is liked or who wants it as an investment.
