Lo Studiolo's jewelry features unique, handcrafted pieces created using a variety of traditional goldsmithing techniques, including both bench work and casting methods.
If you wish, we can recreate a sold-out piece or replicate one of our designs while customizing the size, metal, and stones. This new creation will be distinct and unique compared to the original model, as each piece is individually handcrafted.
Contact us via email, phone, or WhatsApp to discuss a new custom creation.
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.
The jewelry from Lo Studiolo is unique, handmade, and requires special care to prolong its longevity and shine. Our pieces are protected with a surface treatment that slows down the natural oxidation of the metal, helping to preserve the metal's brilliance and/or patina for longer.
To ensure that your jewelry retains its appearance and to mitigate the natural oxidation process of the metals, we recommend the following precautions:
- When not in use, please store your jewelry in its case in a dry location
- We recommend removing your jewelry before washing your hands; if it comes into contact with water, dry it thoroughly
- Avoid wearing jewelry during heavy perspiration, in highly humid environments, or while showering, swimming in the sea, or in pools
- Jewelry should also be removed prior to any physical exercise, as perspiration can accelerate oxidation
- Please also avoid contact with hand sanitizers and cosmetic products such as perfumes and creams
The oxidation patina that may naturally develop over time on bronze or silver jewelry can be removed by gently polishing the metal surface with a jewelry cloth or by using a specific cream or liquid cleaner designed for silver or bronze.
For patinated silver jewelry, we recommend avoiding metal cleaners on patinated areas, as they may damage the patina.
If desired, we would be pleased to offer a deep cleaning, polishing, and surface coating treatment for your Lo Studiolo jewelry upon request.
