A Perfectly Placed Proposal. Tuscany, Italy.

A Note from Alan

With over forty continuous years of experience in jewelry manufacturing and design we stand out among our peers for the close attention we afford to our clients, as well as the designs they entrust us to create.

Alan comes from a family of engineers and lawyers and that foundation instilled in him a strong sense of responsibility as well as attention to the details necessary to succeed in understanding the client wishes while maintaining the integral demands of form and structure that all handcrafted pieces require.

Every piece we create is as unique as the person who wears them. This requires timeless devotion to our trade with our old-world traditional craftsmen along with the latest in technological advancement.
