Our history

Founded in 2005 by Richard Chéret and Olivier Bobin, CIRAM was created with a strong ambition: to make analytical sciences accessible to art market players. art marketart archaeologists and industrialists. At a time when few laboratories offered a multidisciplinary approach, CIRAM stood out for its ability to combine scientific expertise with a keen understanding of business issues.

The company has rapidly expanded internationally, with the creation of CIRAM Corp in New York in 2011, followed by a strategic partnership in Hong Kong in 2012.

In 2014, the construction of the headquarters in Martillac, near Bordeaux, marked a new stage, equipping the laboratory with cutting-edge technical resources to respond to ever more ambitious projects.

As of 2017, CIRAM is doubling the capacity of its materials analysis laboratory and inaugurating a state-of-the-art carbon-14 dating laboratory. To meet the ever-increasing demand, we have also doubled our radiocarbon production capacity in 2022, then tripled it in 2024.

In 2025, we will extend our laboratory by an additional 450m².

Testimonials

CIRAM is a serious laboratory that I enjoy working with, not least because it's independent and doesn't need any outside influence.

I became acquainted with the CIRAM laboratory through the magnificent publication of a highly professional book, demonstrating CIRAM's acceptance and examination methods by the French archaeology community and its services to the State. We subsequently established a very close working relationship. Their expertise has protected me from mistakes, and it's an integral part of a dealer's duty to consult them when in doubt.
