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.

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!!!!

Gateway Builder
Spark your day!

I absolutely love Beiam's modular jewelry. My favorite is the black aluminum necklace with cotton chord. I have ordered a number of cores and love them all, different colors and different moods for different days. Favorites: chrysocolla, turquoise, rose quartz, emerald, amethyst, moldavite. Plus the rainbow glass core, which is something else altogether! The cores are beautifully crafted and the whole gateway construction is a genius idea. I continue to be astonished by the beautiful minerals and crystals mother earth brings forth from deep below, and every single aspect of her expression inspires me day to day.
Beiam delivers with the speed of lightning and every necklace comes beautifully packaged in a little cardboard box. Great gifts for friends!
