Preciosa Bicone MC beads N. 117 (4mm) - 20020 - Light Amethyst

Light Amethyst machine-cut (MC) bicones from Preciosa represent a pinnacle of glass engineering, featuring a precise double-cone geometry that maximizes light refraction. The 4 mm diameter is a standard in professional beadwork, offering a crisp silhouette that maintains its structural integrity even under high thread tension. Unlike pressed glass, these Preciosa beads are finished with high-speed diamond wheels to ensure every facet catches the light with crystal-like brilliance.

The transparent violet glass utilizes traditional Czech formulas that have been refined over centuries in the Crystal Valley. These bicone beads are essential for designers seeking to add depth and texture to their creations without compromising on the authentic feel of genuine Czech craftsmanship. Because they are machine-cut, the edges are sharp and defined, creating a more sophisticated sparkle than fire-polished alternatives.

• Expertly crafted with machine-cut facets for maximum brilliance.
• Uniform 4mm size suitable for precision bead weaving.
• Smoothly polished holes to protect delicate beading threads.
• Iconic Preciosa color 20020 with high transparency.

Incorporating these crystals into your work allows for intricate detailing, especially when used as edging beads around cabochons in soutache or bead embroidery. The tapered shape of the bicone allows it to nestle perfectly into curves, providing a seamless transition between larger focal elements and delicate seed bead borders. For jewelry artists, this shape is indispensable for creating multidimensional shapes such as spheres or geometric clusters.

Professional beaders often combine these faceted elements with softer textures to create visual contrast in bridal or evening wear. For a striking contrast, pair with peridot green, or use amethyst purple and chalk white for a harmonious, sophisticated palette. They work exceptionally well when interspersed with waxed pearl beads in classic necklaces, where the sparkle of the MC beads highlights the satiny luster of the pearls.

Thread compatibility is a critical consideration for longevity, and we recommend using high-performance materials like S-lon FIRE to ensure the sharp edges of the crystal do not compromise the structure over time. Using beading needles size 10-12 will allow for multiple thread passes through the bead, which is necessary for complex RAW (right-angle weave) or netting projects. These Light Amethyst accents provide an affordable yet luxurious option for high-end jewelry collections.
