Frequently asked questions

  • What is an 8-inch fossil coral strand for?
    An 8-inch strand is the bracelet-market cut: roughly one stretch bracelet's worth of beads on a single strand, versus the 16-inch design strand used for necklaces and longer pieces. Bracelet makers, stackers, and wrap designers tend to buy 8-inch because it matches finished wrist circumference (most adult bracelets land between 6.5 and 8 inches once strung on stretch cord with a small allowance). Same fossil coral material as the 16-inch parent collection — just half the strand length, sized to how bracelets actually get built.
  • How many fossil coral beads per 8-inch strand?
    Bead count tracks bead diameter and drill-hole spacing, so treat these as working estimates: about 50 at 4mm, 33 at 6mm, 25 at 8mm, 20 at 10mm, and 16–17 at 12mm. Coins and faceted rounds in this collection can run slightly under those counts because the cut profile changes how beads sit along the strand. Exact count per strand should be disclosed — confirm before buying if you're calculating multiples for a production run.
  • What jewelry works best with 8-inch fossil coral?
    Stretch bracelets are the most common use — one 8-inch strand strung on 0.7mm or 1mm elastic cord typically yields one finished bracelet with a small overlap. Multi-strand stacks pair fossil coral with other earth-tone stones (jasper, agate, petrified wood) for layered wrist looks. Wrap bracelets and memory-wire designs draw from 8-inch strands when only a partial count is needed. The 4mm and 6mm rounds also work as spacer accents between larger focal beads in mixed-bead bracelets.
  • Does Dakota carry fossil coral in 16-inch strands?
    Yes. The 16-inch parent collection is at dakotastones.com/collections/fossil-coral-gemstone-beads and carries the same fossil coral material in additional sizes and cuts oriented to necklace and longer-piece designers. If you're building both bracelets and matching necklaces from the same batch, ordering across both length collections keeps the material visually consistent. Stock and cut availability differ between the two collections, so check both if a specific size isn't showing in 8-inch.
  • What cuts of fossil coral come in 8-inch?
    Current 8-inch stock leans heavily on rounds across 4mm, 6mm, 8mm, 10mm, and 12mm, with coin, chip, and faceted round also represented. Rounds are the workhorse for stretch bracelets; faceted rounds add light return for stacks; coins give a flatter profile for designs that sit closer to the wrist. Fossil coral's natural flower-like pattern reads best on larger rounds and coins where the cross-section is visible. Treatment, if any — ask before buying if it isn't specified.
