Our Vision

"The rings, cufflinks, pendants, amphoras and other art objects displayed on our store windows are inspired by this exceptionally versatile and beautiful gem. Half a century ago, Cousiño was the first company to both specialize in Rhodochrosite as well as exhibit jewelry created with this stone in the National Museum of Decorative Art of Buenos Aires (Museo de Arte Decorativo de Buenos Aires) (1983). Nowadays, along the second generation goldsmith’s family, we are internationally known for the same values which have always distinguished us: the elegance, exclusiveness  and perfection in the manufacturing of our pieces, many of them unique, as a result of a long and personalized relationship with our customers." - María Inés Cousiño (Founder)


All the creations, both in 18k gold and sterling silver, emerge from a process of handmade labor which combines the seal of the most pure modern design and the traditional trade of Cousiño's master carvers, polishers and setters. Specialized workers select the best pieces of Rhodochrosite, which are later transformed into the most beautiful jewels with the Cousiño seal.
