Ethical Practices

Ethical Practices


For each of our jewelry is a particular focus on the origin of the materials used for its creation. Alessia Costa strongly believes in the ethics behind the production of a jewel. For the supply of materials, we rely exclusively on ethically certified partners. Specifically for ethically certified means that suppliers partner of raw materials, such as precious metals and stones, are certified by the Responsible Jewellery Council. All this to get more certainty about the origin of precious stones and materials used in the production of our jewelry.

Responsible Jewellery Council is a non-profit organization, which has more than 800 member companies all operating in the field of supplying jewelry. That entity establishes standards and certifications that protect human rights, labor rights, environmental impact, mining practices, the marketing of products, and all other matters relating to the ethics of the jewelry supply. So oversees normative for specific whole distribution chain of jewels.


About 10% of the population is sensitive to nickel and skin contact with any object containing nickel causes a skin reaction. The reference standard at European level on the use of nickel is the European Regulation 1907/2006 and integrations, which states that the correct values ​​of nickel release are: - Within the limit of 0.5 micrograms / cm2 / week for products that come in contact with the skin with prolonged use; - Within the limit of 0.2 micrograms / cm2 / week for the products entered into pierced parts of the body. The jewelry offered by Alessia Costa Gioielli respect the rules in force. We use nickel free alloys, using palladium instead of nickel. For products already realized, it was decided to carry out the process of rhodium and palladium plating (operation of coating of a metal surface for deposition of a thin layer of palladium) to eliminate any release of nickel.
