Faq and general assistance

Grimaldo jewels are exclusively crafted in our atelier and goldsmith in Florence, adhering to the finest Italian goldsmith tradition. We strive for the perfect blend of creativity, style consistency, innovative technology, and craftsmanship, using only 18 kt yellow, white, and rose gold, corresponding to 750/1000 purity, to create our pieces.

Grimaldo ensures the gold and gems used in our jewelry come from transparent and ethical sources. Our gold is sourced from mines that comply with international sustainability and ethical standards. The diamonds are obtained from responsible suppliers, with a focus on ethical practices and environmental protection. The Casini family, leading Grimaldo Firenze, has built long-standing, personal relationships with these suppliers, ensuring the integrity of our supply chain and the quality of our materials.

Grimaldo is committed to sustainability and responsible sourcing. Our jewels are crafted with 100% responsible gold, obtained from certified mines or supply chains engaged in significant environmental sustainability projects. For over 50 years, sustainability has been a cornerstone of our philosophy, ensuring our production processes are in harmony with the environment and adhere to ethical practices. We strive to maintain a sustainable, respectful, and transparent relationship with our materials sources.
The term ‘hard stone’ is often incorrectly used to refer to semi-precious stones, distinguishing them from more precious stones like sapphires, rubies, diamonds, etc. All gemstones are classified by different indexes, including a hardness index, which indicates their resistance to scratching and chipping. Gemstones used in jewelry usually have a high hardness index, but as hard as a gemstone might be, it is still delicate when set in jewelry.
All diamonds in Grimaldo Collections are sourced from suppliers, aiming to establish a responsible supply chain that respects human rights, protects the environment, and follows proper management practices. White diamonds are of VVS-VS clarity and G-H color. For brown, yellow and pink diamonds, the 4C quality standard is not applicable, and their color ranges, clarity evels, brilliance, and cut are defined by Grimaldo.
