Seed Beads

Seed beads are sized according to aughts (not millimeters) ~ as strung beads per 20mm or 3/4 inch length.  The larger the number, the smaller the bead.  The conversion chart below is for guidance only and all measurements provided are approximate.

My seed beads are sold by weight or by *hank* where noted.  Pre-strung hanks may differ in size, strand count and weight depending on bead size, manufacture and country of origin. Loose beads come in zipper bags, packaged by weight in grams or ounces. One ounce (1 oz.) packages contain approximately 28-30 grams.

**Bead colors may vary slightly from photos depending on monitor settings**

* * CZECH seed beads are uniform in size with smaller holes and thicker walls. They are best known for their traditional smooth, rounded shape and wide range of colors.

* * JAPANESE seed beads are very uniform in size but more cylindrical in shape, with large holes and thinner walls. Most popular for their wide variety of colors and finishes.

* * FRENCH seed beads are more irregular in size and shape, but have larger holes than the Czech seed bead with colors that are the most durable and resist fading. They are most popular for traditional beadwork and artifact reproductions.

* * ITALIAN seed beads are no longer being produced, and are extremely rare. Those still on the market are from vintage stock and are highly prized by collectors. The 24/0 seed bead is the smallest ever made and used primarily for restoration and reproduction work for 1700 thru early 1900 beadwork. Once referred to as "sand" beading, the intricate work produced from these tiny micro beads often looks more like cloth than beadwork.
