Standard Black Gateway



The Gateway is a modular necklace design that holds interchangeable cores. 

The chain you choose is what keeps your cores secure in your necklace. To change out the core you’re wearing, simply remove the chain from the gateway and tip it out into your palm. Slide your next core in through the top, run your chain back through the side holes and go about your day! All standard sized cores fit in this model.

Chains are sold separately to allow for individual size and color preferences. Please click here to find your preferred chain.

The Silver and Black Gateways are made from stainless steel, and the Black features a strong Cerakote finish.

Blue Goldstone

Beautiful Stone

My blue goldstone was a beautiful midnight blue color and as sparkly as I hoped it would be! It's been a fantastic accent for outfits and it reminds me why I love shopping here. (Plus, it was shipped and delivered right on time!)


All of these cores are beautiful. Color can be slightly darker or lighter but still fantastic and shocking durable

Clear Quartz

Crystal Clear Quartz

I have wanted a clear quartz core for some time now, and I was so happy to see this offering. I wear it with either the silver or black gateways, looks great with either one.

What a light lovely mix

This is an unexpected mix of stone. So pretty and delicate! I love it!

peaceful light blue

This is a great core, love the light colors, and goes really well with the silver gateway. I also connect with the meanings behind the stones - awareness, higher consciousness, motivation and inspiration.

Love this core! Looks awesome in the black and silver

Super pleased

Really like this travel kit. Now I don’t have to choose which core and can bring all my faves!

Beautiful work, sustainable workmanship

This is my low-key favorite stone that I have. The red, particularly against the black core, is stunning. I love all the stones I own, but this one is my go to for just about any and all occasions.

Creates Jealousy!

My friends and coworkers ask me about the "stunning" necklace I wear from Beiam! They can't believe that the cores are interchangeable and how beautiful they are. It's so easy to change my core based on my mood or outfit. I can't wait to purchase more!!!

1.5mm Snake Chain

Love How it Looks!

Had this chain for about a month now and I love it. It is great quality and feels nice to wear. It’s also got a nice shine that is hard to get with some other chains that end up looking dull. Definitely would buy another :)

Love the Look

I've been rocking the black gateway since I first found this website, but for the darker stones, such as the onyx, the tiger's eye, etc, the silver is such a better contrast. It's been a blast playing with the different looks.

1.5mm Rounded Box Chain
Kristen Silvia

I have purchased several cores, and necklace chains. I love each one. I especially like being able to interchange cores for a fresh look.

The Valkyrie
Kelly Kruml
All time favorite

I lost my last sterling gateway on a trip and was so sad. I need this necklace. I ordered the valkyrie and I love it so damn much! The shape of it is so elegantly fierce. It's so beautiful and the cores are (as always) amazing. I wear this every day. I also bought the rose gold gateway for travel, so I never lose my favorite necklace again. This. Is the. Best.

Great item

Very pretty chain. Simple, great looking
