The measurement of this bead is 8 x 3.5mm. Double strand marquis shape with a faceted front. These are very old and premative so the cuts are not as clean as contemporary beads. This makes these even more valuable to the collector. Yummy and unusual to come by. Made in Czechoslovikia. They are from the early 1900's. What a find! Glass nailhead beads were used in the days of the flapper to embellish garments before sequins were developed. You will receive 24 beads per lot.
