Master Alloys for the Utmost Level of Purity
PURA® is a family of master alloys developed to achieve the highest standards of chemical purity and metallurgical consistency in jewellery alloy production. Engineered through an extremely selective raw material sourcing process, PURA® is designed to minimise contaminating elements that may compromise the behaviour and quality of the final alloy. Its controlled production approach ensures superior surface quality, highly repeatable behaviour and a significant reduction of metallurgical defects.
Engineered for Maximum Purity and Process Consistency
PURA® is developed with a clear objective: achieving the highest possible level of purity in a master alloy. This begins with an extremely rigorous selection of raw materials, followed by dedicated production processes designed to minimise contamination and preserve metallurgical integrity. The reduced presence of unwanted elements contributes to cleaner alloy behaviour, improved surface quality and greater production consistency. At the same time, the controlled metallurgical composition ensures repeatable performance across different manufacturing batches and processes. The result is a master alloy family designed for manufacturers seeking maximum reliability, cleanliness and process stability in jewellery production.
- Extremely high level of chemical purity
- Rigorous selection of premium raw materials

- High constancy and repeatability in production behaviour
Frequently Asked Questions
PURA® is developed to guarantee exceptionally high levels of purity for precious metals, helping manufacturers achieve consistent alloy quality and reliable production results.
Higher purity reduces the presence of unwanted contaminants that may negatively affect casting performance, colour, mechanical properties and final product quality.
No. While PURA® is produced using highly refined precious metals to minimize impurities, REACH compliance cannot be guaranteed solely by the alloy itself. The finished jewellery must be assessed after all manufacturing processes through the appropriate release (migration) tests, as required by the applicable REACH regulations. Compliance should always be verified on the final product.
