patented design

After years of designing I-beams for high-end architecture in London and NYC, the idea of an extruded shape is second nature for any architect or structural engineer like Beth. Now let's take that concept, change the cross-section and scale it down. Something so different it deserved a Design Patent.
We think that's pretty cool.

Custom jewelry like you’ve never seen before;
designed by you and crafted with the finest materials in New York City

All good design is mathematically based. 
Designer, Creative Director & Founder Beth Macri utilizes her background as a Structural Engineer to create mathematically derived jewelry that is not only beautiful, but also pretty clever.
