This is a very cool, color changing color from Swarovski. It is designed to imitate the real Alexandrite gemstone by changing color in different lights. In natural daylight it appears a pretty pale blue, and under incandescent light the beads it appears a soft purple. Bicones are shaped exactly as the name suggests- like two cones stuck together! These crystal bicones add a little sparkle to any design at an affordable price. Made in Austria. Qty:Bag of 24.
