Eternium Necklaces are made of industrial grade silicone and aluminum. They are lightweight, waterproof, and easy to maintain. The best part is there is no clasp to worry, so you can slip it right on and off.

It also glows in the dark, just charge it by wearing it during the day or put it in front of a light for a minute and it will start glowing!

A little about us: We started our company by making hemp necklaces and bracelets while living in Southern California. It always made us sad that our product would get ruined after it got wet a few times and would eventually fall off due to the material. So we decided to find an alternative; aluminum. Strong, durable, shiny, easy to clean, and lightweight. It was the perfect medium for how we wanted to use it; everyday wear and not have to take it off during a shower.

Here we are years later and we have grown due to the support of our family and local community. We offer numerous products ranging from bracelets, anklets, necklaces, keychains, and even custom pieces for returning customers.

Thank you for checking us out!

Care Instructions:
-Mild detergent / soap
-Warm water
-Dry with soft dish towel

What size bracelet should I get?

This is a fantastic question! Since our bracelets/anklets don’t use a clasp, getting the size right is key.

  • Our bracelets will feel snug when slipping over the hand, but should sit comfortably on the wrist without biting into the skin or leaving marks.
  • To find the perfect fit, measure your wrist and add half an inch for the best comfort.

General Sizing Guidelines:

  • Kids under 10: Small (6-7" wrist); if they are bigger, they may fit a Medium.
  • Women: Typically fit a Medium or Large (7-8" wrist).
  • Men: Typically fit a Large (8-9" wrist), and XL men may require a custom size.

Care Instructions

To keep your jewelry in great shape, follow these simple care tips:

  • Use mild detergent or soap with warm water.
  • Dry with a soft dish towel.
  • For extra shine, use a jeweler's cloth.
Does this bracelet glow in the dark, or can you make them glow?

Yes! Most of our bracelets have a glow-in-the-dark element, with the exception of darker colors like black. The brightest glow comes from neon colors like green, yellow, blue, red, white, and pink.

How do you make the bracelets glow?

The glowing feature is built into the material, and it won’t fade like a glowstick. The glow lasts for the lifetime of the bracelet.

  • To maximize the glow, wear the bracelet during the day—it absorbs light and shines at night.
  • For an instant boost, you can 'supercharge' the bracelet by placing it in front of a lamp.
