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.
