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
