Swarovski® Austrian Crystal
These Crystals will brighten any room. Hang them where the sun will shine through and send rainbows all over your room. As far as rainbows go, the general rule of thumb to follow is: the more facets there are, the more rainbows, the bigger the facet the bigger the rainbow.
The Aurora Borealis (AB) coating makes crystals sparkle just a little more, and spin just a little bit brighter rainbows.
