Size of the sieve agate beads: 10mm
An unusual "stone" - from the Harz Mountains!
Sieber agate is not agate, but bluish slag from the Steinrenner smelter, which was created during the smelting of iron ore from the Eisensteinberg.
The stone is named after the Sieber River in the Sieber Valley (Harz Mountains); the misleading addition "Agate" refers to the banding of the material. Very similar to the Sieber "Agate" is the "Bodeachat" from the river Bode (Saxony-Anhalt, Harz).

Individual design jewelry with gemstones: String Beads, "Sieber Agate" (blue slag), 10mm

Hello! My name is Marco Schreier, I am the stone-loving founder of the Mineralienhandlung GmbH of the same name. My career in the field of gemstones, precious stones, pearls and designer jewelry only began relatively late.
Originally, my attention was focused on collector's minerals, then on polished stone products such as tumbled stones, etc. Later, drilled stones were added, which, worn on a leather strap, were the first jewelry we offered. With the establishment of our office in Bali, Indonesia in 2001 and shortly afterwards our office and company in Hong Kong, I created the basis for integrating many of my favorites such as special crystals, specially cut, rare gemstones, free-form cabochons, beads and pearls into my own jewelry.
Chili Jewels® is our professional brand for the specialist trade with low wholesale prices and outstanding offers from our own production of silver jewelry, stone jewelry, necklaces and bracelets with real stones.
