Gold
≥ 99.95% pure gold (999.5 fineness)
AURUM pieces are cast exclusively from 24-karat gold sourced from leading Swiss precious-metal refineries including PAMP, Argor-Heraeus, Valcambi and Umicore. All bullion used in production meets a minimum purity of 999.5. Each piece undergoes internal verification procedures, including hydrostatic density measurement, ensuring full material integrity and solid construction.
Molten 24-karat gold exhibits excellent fluidity, allowing it to flow into fine details and reproduce sharp edges with high fidelity when casting conditions are professionally controlled. Its high density and surface tension enable smooth, continuous fills, resulting in clean surfaces and well-defined features with minimal porosity

Platinum
95% pure platinum
AURUM pieces can be cast exclusively from high-purity platinum sourced from internationally recognized precious-metal refiners. All material used in production meets a minimum purity of 999.5. Each piece undergoes internal verification procedures, including hydrostatic density measurement, ensuring full material integrity and solid construction.
Molten platinum exhibits controlled flow characteristics at elevated temperatures, allowing it to fill intricate geometries and reproduce fine details when casting conditions are precisely managed. Its high density and structural stability result in durable, well-defined features with excellent surface integrity and minimal porosity.
