Who we are
A network you can rely on.
Our work rests on a verified ecosystem of laboratories, Swiss infrastructure partners, auction houses and strategic cooperations. Some we name openly — others, for reasons of discretion, we do not.
01 — Gemmological laboratories
Globally recognized authorities for authenticity and origin.
Every stone in our portfolio is verified by at least one of these laboratories. Certificates include findings on treatment, origin (where determinable) and gemmological classification.
SSEF
Swiss Gemmological Institute — globally leading in gemstone testing and origin determination.
GRS
GemResearch Swisslab — internationally recognized for colored gemstone certification and quality assessment.
SIG
Swiss Institute of Gemmology — Swiss institute for gemmological education and examination.
02 — Swiss infrastructure
Storage, insurance, bonded warehouse.
Storage
Swiss bonded warehouse
High-security custody in Switzerland, VAT-neutral, in a stable jurisdiction. Clients receive individually assigned storage certificates.
Insurance
All-risk cover
Full insurance cover at the professionally appraised market value — including transport, examination and storage.
03 — Auction house partners
Renowned partners, nationally and internationally.
We work with selected auction houses in Switzerland and abroad — for acquisitions from estates, for resales on behalf of clients and for market observation and valuation.
For reasons of discretion and contractual confidentiality, we do not name auction house partners publicly. We are happy to discuss this in a personal conversation.
04 — Wealth management & structuring
Strategic cooperations for holistic solutions.
We work with selected Swiss wealth managers, private debt specialists and insurance brokers. Through pioneering cooperations, we offer competitive, holistic high-end structuring — tailored to individual situations.
Our partnerships enable the seamless integration of tangible asset strategies into existing wealth structures — from protection to succession planning.
05 — Premium partnerships
Beyond the gemstone market.
We maintain relationships with selected private jet and yacht brokers. Our clients benefit from exclusive conditions, discreet handling and professional advice on premium investments beyond the traditional gemstone market.
06 — Democratizing access
Colored gemstones for all investor segments.
Together with our partners, we are democratizing access to this traditionally high-entry-point asset class. Through these platforms, even smaller retail investors can participate in physical colored gemstone investments.
