What are Cores?

Our jewelry is based around the idea that everyone is an individual, a unique being unto themselves. With that in mind, we created a modular jewelry line to help the wearer express themselves as that unique being.
Cores are the essence of this modularity.
Cores are interchangeable rods within a specific jewelry line: i.e. a Core that fits into a Portal Series necklace will also fit into a Portal Series bracelet.
They come in many materials: minerals, gems, woods, glass and resin. Most of them are handmade at our studio, but some are made by outside partners.
Some of the ones that we make in-house are cast with resin and hand-finished on a faceting machine. This includes most of the mineral Cores you see on the site.
With a large variety of colors, minerals and gems for you to choose from we're certain you'll find your Core.

Fantastic customers service

Gateway with Chain/Cord


I love the peice my goal is to get more cores and to gain a collection of them. One suggestion is to get a plug for the top so it moves around less inside of the housing

Love beiam!

Absolutely in love with the beautiful design concept and pieces from the beiam line. Many have complimented my necklace and I’ve referred them to your website 😊. In fact, I believe a few have purchased their gateways. So glad I discovered beiam on Instagram!!!!


The customer service was amazing, the item is great and I am really enjoying it.
