Wedgwood Article Dating

If you have a Wedgwood piece and are uncertain as to what year it was made, here's a link to help you out (it's how I found out my necklace -- pictured below -- was made in the year 1900).

My mum bought me this necklace in Fenelon Falls, Ontario as a grad present. It's a cameo and I think that it's a fairy in the center.
