Jet Black Glass Beads 4mm
Minimalist bracelet designers reach for these when thread tension matters. Your needle glides through the centre hole without snagging, and every bead aligns flush against the next—no wobble, no gaps. These jet black glass beads 4mm become the punctuation marks in colour-blocked patterns, the sharp dividers between rounds of seed beads, or the structured grid foundation for woven right-angle work where alignment is everything.
- 4mm square profile with clean, machine-cut edges
- Opaque jet finish—no transparency, pure light-absorbing black
- Mirror-polished faces that catch ambient light without shimmer
- Threading hole approximately 0.8mm, suited to 0.4mm wire or thread
- Twenty beads per packet, consistent sizing across the batch
- Czech pressed glass construction with weight and durability
Stack them as uniform spacers between 6mm gemstone rounds to create breathing room in a design, or weave them into ladder-stitch foundations where their straight edges lock together predictably. They anchor floating pearl stations without competing visually, and their small footprint means you can build three-bead clusters that still read as delicate rather than chunky. When knotted onto silk cord, they sit tight against the knot without rolling or twisting.
Under studio lighting, these show a cool, neutral black—not warm charcoal, not blue-toned. The polished surface reflects pinpoints of light from overhead sources but doesn’t sparkle or shift tone. Pair them with sterling silver findings for high-contrast monochrome work, or let them recede as structural anchors behind coloured focals.
