Ethical Sourcing
Beyond the Certificate
A gemstone's ethical status is determined not by a certificate but by what happened before the certificate was issued. A fine ruby or sapphire may pass through many pairs of hands between the mine and a collector — local broker to rough dealer, rough dealer to cutter, cutter to polished gem trader, and trader through wholesalers and importers to the final point of sale. At each stage, a margin is extracted and a piece of the provenance story is lost. By the time a fine emerald reaches a collector, no single person in the chain may be able to state with confidence where it was mined, how it was cut, or what treatment it received.
This is the standard model. It is not ours.
The master cutter is the first person to determine whether a rough crystal becomes ordinary or extraordinary. In the finest cutting centres, that determination is made by someone who has been learning since childhood. In Chanthaburi, heat treatment and faceting expertise has been refined through generations of family workshops. A cutter's knowledge of how to orient a sapphire, how to position the first preform, and how to draw out colour through the precise angle of a facet is not taught in schools. It lives in families. The same is true in Ratnapura, where lapidaries have shaped sapphires from alluvial gravels for centuries using techniques that have changed remarkably little. You cannot responsibly source gemstones without knowing the people who cut them.
This is where our model begins — not with a certificate, but with a relationship at the cutting house itself.
Through longstanding partnerships with cutting families and trusted mining partners — some spanning more than two decades — we frequently acquire entire cutting runs at the source. Capital reaches the people who shape the gemstones rather than accumulating through layers of intermediary. Because we are present at the source rather than purchasing downstream, we can trace each gem from mine to cutting table to the Skyjems archive without relying on a broker's word.
Our work in the Colombian emerald trade illustrates this most clearly. Nearly all Colombian emeralds carry a jardin — the characteristic network of internal fissures and mineral inclusions that gemologists use to confirm natural origin and identify the specific mine district. The standard industry practice is oiling: filling surface-reaching fissures with cedarwood oil or resin to improve transparency. This is accepted by every major gemological laboratory and graded on a defined scale. There is nothing wrong with a well-disclosed, minor oil treatment on a fine Colombian emerald. What is wrong is when the treatment level is misrepresented or undisclosed — which happens routinely when a gemstone has passed through too many hands for anyone to be certain of its history. Working inside Colombia's emerald networks, from the mines of Muzo and Chivor through the cutters and dealers of Bogotá, means we know exactly what treatment a gemstone has received and can state it without qualification.
We do not source gemstones from regions subject to international sanctions or identified by leading gemological authorities as conflict-affected. All treatments are fully disclosed — their nature, their extent, and their effect on value.
All gold, platinum, and silver used in Skyjems commissions is recycled — recovered and refined to the same purity as newly mined metal, with a materially lower environmental footprint. Clients who prefer newly refined metal may request Canadian-origin gold or silver, sourced domestically. We work exclusively with recycled platinum.
Every gemstone acquired from Skyjems — at any price point — is accompanied by a Skyjems Certificate of Authenticity, documenting the gem's identity, origin, and treatment status as assessed by our archive. For clients who require independent third-party certification, full laboratory reports — including or excluding appraisal value, as preferred — are available on request through Harold Weinstein Ltd., Canada's most respected independent gemological laboratory, operating in Toronto since 1977 with accreditation from the American Gem Society as an Accredited Gemological Laboratory. International reports from the GIA, Gübelin, AGL, and SSEF are also available for appropriate gemstones by arrangement.
For collectors who require it, the documentation is complete and unbroken. Every gemstone entering the Skyjems archive has a clear, accountable path from the earth, through the hands of a master cutter whose name we know, to the collection.
