Made in the Czech Republic by Matubo. GemDuos are pressed glass two hole beads in a diamond shape. These beads fit together snuggly when strung together. With two holes approximately 0.8mm in diameter, running parallel across the width, one hole in each half of the diamond shape. The large holes allow you to thread through several times giving these beads a great deal of flexibility when using then in beadweaving patterns.
This bead has a flat back whilst the bevelled edges make it easy to recognise the top or front of the bead.
The Gemduo measure 8mm x 5mm in size and there are approximately 76 beads in 10g.
