Notaries / Lawyers
Often misunderstood or fantasized about, minerals remain a niche market that has undergone significant changes.
At the time of an inheritance, it is not uncommon to come across pieces of furniture containing a
« rock » component, or even confronted to an entire collection of minerals. Yet, without established benchmarks, their patrimonial and succession planning can be complex.
As with any specialized field, appreciation of a valuable specimen or collection requires in-depth knowledge, where every detail makes a difference.
We position ourselves as your privileged partner to assist you in accompanying your customers.
Advising
We advise institutions, companies, interior designers and private collectors in their approach.
