ItalianoExperience and processing
Trettre has been a leading company in the Italian fashion bijoux market for over ten years.
After a long experience in the goldsmithery, silverware and costume jewelry sectors, the three partners joined forces with the desire to offer strictly Made in Italy products in line with current trends.
The first goal they achieved was to organize a creative and dynamic group, always ready to improve and renew itself.
The company’s craft work aims to satisfy all customer needs with great care, attention and flexibility.
The activity of Trettre
The activity of Trettre is mainly focused on the production of finished items, such as: bracelets, necklaces, earrings, key rings, twins; shaping raw materials such as silver, steel, bronze, brass, copper and Plexiglas.
