These gorgeous crystal beads will create a one of a kind look in your handmade jewelry designs and craft projects. These crystals are a Helix shape with many facets on the front and back. They are very similar in shape to the Swarovski pendant Art. 5020 Helix. As is the nature of Chinese crystal, some beads may have small nicks and scratches on them. These beads measure 7mm long by 7mm wide. The hole measures .5mm to 1mm in diameter (the hole size may vary on each bead). There are 36 beads on a strand. Each strand measures about 10" inches long. These beads are made of Chinese crystal glass and were made in East Asia.All photos have been taken indoors with daylight, but as always, computer and mobile screens display colors differently.
