Metals

 

The metals used for our jewelry include bronze, silver, gold, and platinum.

Bronze, an alloy of copper and tin, is naturally nickel-free.

Like silver, bronze is a “living” material that can develop a patina over time due to natural oxidation. Humidity, water, and skin pH levels may accelerate the metal’s oxidation.

Specifically, an acidic skin pH can cause slight oxidation, especially on rings, and may lead to a subtle greenish patina on the skin after prolonged contact. This effect, which can be removed with regular washing, is harmless, non-toxic, and does not indicate an allergic reaction.

Lo Studiolo jewelry is crafted in sterling silver (925 silver), an alloy composed of 92.5% silver and 7.5% other metals.

In some cases, our silver jewelry is given a final black patina. This dark finish, which makes each piece unique, is a surface treatment achieved by applying acids that react with the metal surface. Over time and with wear, the patina will gradually fade, especially in areas where friction occurs, revealing the natural silver beneath and creating a captivating chiaroscuro effect.

This natural process should not be seen as a flaw but rather as an evolution that enhances the uniqueness and personal character of each piece from Lo Studiolo.

Gold (18k) and platinum are also used for our most refined creations. These metals are highly durable, resistant to oxidation, and hypoallergenic. While they maintain their natural color and brilliance over time, regular care such as gentle cleaning and proper storage will help preserve their shine.
