I have used many Swarovski Crystals in my creations and just love them. The way the sparkle and shimmer in different kinds of light, the colours they come in and I suppose I am a Swarovski Crystal whore!
Recently I purchased a large Swarovski Crystal and wanted to make an amazing piece. OMG I hadn't bought a crystal so big, well roughly 30mm by 30mm, it's big to me.

I was amazed whilst taking photographs of it at the different colours streaming through. Wow did it sparkle and the sun just shone back at me. I was absolutely in a magical, colourful world of my own. Putting it against the white stand made it look a beautiful shade of blue although it actually is clear.
The photgraphs alone do not do it justice. You really have to see it for real. This second picture shows a rainbow of colours from one position but just look at the last photograph, It's awesome!

I just teamed the fan/shell shaped crystal with a sparkling silver bail, half a dozen white fresh water pearls and a bright flower patterned silver plated chain.
