Ethical Practice

Coloured gemstone supply chains are complex. Rough may be traded in mixed parcels, origin can be difficult to evidence, and records may not follow a stone through every stage. Risk is reduced through trusted relationships, recommendation and review, though full assurance is not always possible.

Provenance is therefore described in tiers, so that the basis for any statement is clear.

Documented means independent reports are held where applicable, alongside supplier invoices and atelier production records.

Declared means supplier declarations and purchase records are held, including disclosed treatments and declared origin where provided.

Repurposed means the stone was acquired at auction, from estate sources, or from reclaimed jewellery. Earlier history may be unknown, and that is disclosed.

As a principle the House does not accept client-supplied stones or metals, because provenance and traceability cannot be assessed to its own standard. Exceptions are considered case by case, with agreed boundaries and clear disclosure.

For diamonds the House prefers established suppliers and, where relevant, the warranty practices commonly used in the trade for conflict-related risk. High-value stones are normally accompanied by an appropriate report. Where a diamond is repurposed from older jewellery, it is disclosed that its earlier history may not be fully evidenced.

Absolute wording is avoided. Where a term could imply complete certainty beyond what documentation supports, it is replaced with language grounded in the provenance tier and the records held.

Natural gemstones are used almost exclusively. Where a synthetic or laboratory-grown stone is used, it is either aesthetically explicit by design or disclosed within the production description.

Treatments are disclosed when they are not obvious, not standard trade practice, or when they materially affect durability or value. Where stones are described as investment grade, documentation is treated as essential.

Artisanal mining is not treated as something to be erased. In many regions small-scale gem extraction exists alongside other livelihoods, and stones reach the market through local cutters and small communities of trade.

Stones originating from such contexts are bought through vetted cutters and purveyors whose conduct, professional affiliations and reputation can be assessed. Where accreditation is absent, the case is reviewed individually and pursued only where trust and responsible conduct can be justified.

The House follows the responsible sourcing expectations widely recognised within the jewellery sector, including heightened caution where a supply route may touch a conflict-affected or high-risk area.

Where a supplier cannot provide a satisfactory basis for risk assessment, the House does not proceed, or the sourcing plan is revised. Where certainty is limited, that limitation is not masked with language implying otherwise.

Information on precious metals varies by workshop and supply route. Metal sourced through partner ateliers follows their established procurement pathways. Metal purchased directly for artisanal work under the House’s supervision comes from dealers who provide responsible sourcing assurances appropriate to the transaction.

Recycled metal is used where possible. Post-industrial recovery and melting is recorded internally when applicable, and purchase records are retained.

For special materials and processes, including titanium, sourcing and processing is handled either by the House or by associated workshops within their professional frameworks. Where refiner-level origin data is not available, it is described as unspecified.

Making is distributed across Portugal, France and Switzerland and includes CAD modelling, fabrication, casting, setting, finishing, engraving and lapidary work, depending on the piece.

Labour models vary across partners and may include employees, independent artisans and specialist subcontracting. Assurance comes from close personal relationships, the selection of reputable ateliers, and where applicable the standards and audits those ateliers choose to maintain within their own operations.

Hazardous substances and processes are managed by workshops in accordance with local regulation and professional safety practice, including appropriate ventilation, protective equipment and responsible handling of waste and residues. Where a workshop-specific environmental management system is not known to the House, none is claimed.

No formal carbon footprint is measured. Longevity and repair are prioritised, and measurement is intended to improve over time.

Within the scale of the House, waste is reduced through careful planning, metal recovery where possible and deliberate purchasing. Acquired and restored professional tools and equipment are used where appropriate, and materials are reused internally where they remain suitable for high jewellery standards.

Packaging and presentation objects are sourced from small-scale makers in Portugal and Italy, and from suppliers selected for responsible practice where possible. Recyclable components are prioritised, while acknowledging that full upstream assurance may not always be recorded.
