Howlite - 8-Inch

Naturally white with spider-web gray matrix, howlite gemstone beads are a calcium borosilicate discovered in 1868 by geologist Henry How in Nova Scotia. These 8-inch strands are precision-cut and drilled with smooth 0.8 mm holes, ready to string as sleek, marble-inspired accents or to accept turquoise dyes for a classic robin’s-egg look. Long regarded as a calming stone that quiets an overactive mind, howlite suits jewelry meant to soothe while adding crisp, modern contrast.

Frequently asked questions

  • What is an 8-inch howlite strand and who is it for?
    An 8-inch strand is a bracelet-length cut of the same howlite Dakota stocks in 16-inch design strands. It's sized for makers building a single stretch bracelet, contributing one row to a multi-strand stack, or prototyping a colorway without committing to a full design strand. The 16-inch strand remains the standard for necklaces and longer wrap work; the 8-inch is the bracelet-trade format. Mineralogy, cut, and finish are identical to the 16-inch parent — only the strand length changes. Howlite's chalky white body with grey matrix veining reads cleanly at bracelet scale and pairs with most accent stones.
  • How many howlite beads come on an 8-inch strand?
    Bead count depends on the diameter and the drill-hole spacing, but as a working estimate: 4mm rounds yield roughly 50 beads per 8-inch strand, 6mm about 33, 8mm about 25, 10mm about 20, and 12mm about 16. Shaped cuts like coins, squares, and chips vary more — coin and square counts depend on bead thickness, and chip strands are sold by length rather than count. For a standard 7-inch wrist with stretch cord, an 8-inch strand of 6mm or 8mm rounds typically finishes one bracelet with a few spare beads.
  • What jewelry do designers make with 8-inch howlite strands?
    Stretch bracelets are the primary use — one 8-inch strand of 6mm, 8mm, or 10mm rounds strings directly onto stretch cord for a finished wrist piece. Designers also use 8-inch strands for multi-strand stacks (three to five strands worn together, often mixing howlite's white with darker accent stones), wrap bracelets on leather or cord, and memory-wire builds. The 30mm double-drilled howlite works as a focal in two-strand cuff designs. Chip strands suit knotted bracelets and macramé. For necklaces or longer beaded ropes, the 16-inch parent strand is the more efficient buy.
  • Does Dakota carry howlite in 16-inch strands?
    Yes. The 16-inch parent collection is at dakotastones.com/collections/howlite-gemstone-beads and carries the same howlite material in the design-trade standard length, with a broader range of cuts and sizes. If you're building necklaces, long wraps, or production runs where per-bead cost matters, the 16-inch strand is usually the better unit. The 8-inch collection here is the bracelet-market subset. Cut availability overlaps but isn't identical — some shapes are stocked only in one length.
  • What cuts and treatment notes apply to howlite?
    The 8-inch howlite assortment includes rounds (4mm through 12mm), coins, chips, squares, and a 30mm double-drilled bead. Howlite is a soft stone — Mohs around 3.5 — so handle with care during stringing and avoid abrasive cleaning. Note that howlite is commonly dyed in the trade to imitate turquoise, lapis, and other stones; the undyed natural material is white-to-grey with darker veining. Treatment status (natural, dyed, stabilized) should appear on the individual listing — ask before buying if it isn't specified. Pairs cleanly with turquoise, lapis, onyx, and most jaspers at bracelet scale.
