Bijuland is a wholesale bead and craft materials supplier based in Plovdiv, Bulgaria. The Cat's Eye Resin Beads — Ball category (мъниста котешко oko топче — manista koteshko oko topche) covers spherical resin beads with an internal optical fibre layer producing a chatoyant light effect — available in a Big Package and a Small Package — within the broader Resin Acrylic Beads section. Wholesale and retail purchase available, with shipping across Bulgaria and Europe.

Cat's eye resin beads (мъниста котешко oko — manista koteshko oko) are resin acrylic beads that contain a fine layer of optical fibres embedded within the bead body. When light strikes the bead, these fibres concentrate and reflect it as a single narrow band — a bright line of light that appears to float on the surface of the bead and shifts position as the bead or light source moves. This optical phenomenon is called chatoyancy (from the French chatoyant — "cat's eye"), the same effect seen in natural gemstones such as chrysoberyl cat's eye and tiger's eye. In resin cat's eye beads, the effect is produced artificially by the fibre layer rather than by natural mineral structure, but the visual result — a luminous moving line against a coloured background — is closely comparable. The ball shape is the standard and most widely used form for cat's eye beads: the curved spherical surface displays the moving light band evenly from all angles, making the chatoyant effect clearly visible when the bead is strung in a bracelet or necklace and moves naturally with wear.

Cat's eye resin ball beads are available in a wide colour range — from deep jewel tones to pastels — making them versatile across different jewellery styles. The chatoyant moving band is the primary decorative feature, so these beads work best in designs where they have space to be seen individually: as the main bead in a single-strand bracelet, as evenly spaced feature beads in a multi-bead strand, or as a single pendant bead. They pair well with plain transparent acrylic beads or small spacer beads in a complementary colour, allowing the cat's eye effect to remain the focal point of the design. The Big Package contains a larger quantity at a lower cost per bead — suited to jewellery makers producing cat's eye bracelets or necklaces in volume, and for resellers stocking a colour range. The Small Package is suited to individual makers sampling a colour or completing a specific design.

Bijuland ships from Plovdiv, Bulgaria and supplies jewellery makers, craft studios, and bead resellers across Bulgaria and Europe.
