Not Your Grandma's Jewels

Cooper Supply

Cooper Supply is about resilience. Jewels and trinkets that withstand time - reminding us that we too can endure anything. It pays homage to the moments these pieces lived through and the stories they could tell us. This capsule collection - which is made up of antique bits and pieces from my personal treasure sourcing trips - is named after the family business to honor those who came before us; the way the pieces of this collection commemorate their own unique story too.

Mütter Museum Collection

America's finest museum of medical history, the Mütter Museum displays its beautifully preserved collections of anatomical specimens, models, and antique medical instruments in a nineteenth-century "cabinet museum" setting. This unique treasure is one of our favorite museums in Philadelphia and we are so thrilled to offer this collaborative collection again for Museum Shop Sunday, in which a portion of sales directly supports the Mütter Museum.

My new favorite jeweler. I have the Crystal Collar and a crystal ear threader. I love them both. I've received compliments on both pieces each time I've worn them. So unique! The packaging/presentation is gorgeous, and service is fast and very friendly. I will definitely be ordering more.

I just wanted to thank you again for the beautiful craftsmanship and getting the bracelet out to me so quickly, it may have been the first time I had a V-Day present more than a week before v-day!  Britta absolutely loves her bracelet!  

Devlin H.

Kat does amazing work! I approached her about doing a custom ring to replace one I had lost and she was fabulous from beginning to end - including sourcing stones for me to choose from and getting my input on all the design details. The ring is perfect, thanks Kat!
