Jewelry-making ideas
Use the neutral light-grey glass in delicate earrings, layered necklaces or coordinated bracelet designs. The bulk quantities suit repeat designs and larger beadwork projects, while the rounded facets blend with other jewelry components in modern or vintage-inspired pieces.
Czech glass tradition
Made in Northern Bohemia, where glass beadmaking dates back to the 14th century, these beads are molded, machine-faceted and polished in direct fire. Fire polishing creates brilliant, scratch-resistant glass surfaces with softer facets that help soften the hard lines of machine-cut crystals. These cost-effective beads are usually made in smaller batches, so sizing and shape may vary slightly.
Color and size notes
Natural glass properties and different raw-material lots can cause slight shade variations. Larger sizes tend to appear darker because they contain more glass. Images are for reference; lighting, monitor settings and web browsers can affect the color shown. The comparison charts illustrate dimensions only, not the actual Black Diamond color or additional sizes available in this listing.
Your satisfaction is guaranteed.
