Siber Agate (Man-Made / Copper Slag)

Siber Agate is a fascinating man-made material with a rich history tied to ancient metallurgy. Despite its name, it is not a natural agate. Instead, Siber Agate is a glassy copper slag — a byproduct of historical copper smelting processes that date back over 1,000 years.

Formed when copper separates from copper ore at extremely high temperatures, this material cooled into a smooth, obsidian-like glass with deep, saturated coloring. True Siber Agate is most commonly found in shades of brown and black, with the highly sought-after blue variety making up only a small percentage of the material.

Historically, Siber Agate originates from old copper smelting sites in Saxony-Anhalt, Germany, where ancient extraction techniques unintentionally produced this beautiful glassy byproduct. Today, it’s admired for its luminous polish, bold color, and unique blend of human history and mineral aesthetics.

Details:

  • Man-made material (copper slag byproduct)

  • Glassy, obsidian-like appearance

  • Deep blue coloration (rare variety)

  • Smooth, high-polish finish

  • Appreciated for décor, collecting, and intention work

Siber Agate is perfect for those who value striking beauty, historical intrigue, and full transparency about material origin.

Lovely sandals!
I highly recommend! These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.
