Sea Sediment Jasper is also known as Imperial Jasper or Impression Jasper and this stunning blue color is sometimes called Aqua Impression Jasper, it is a high quality, man-made composite stone. They are often sold as genuine natural semi-precious stones. I choose the highest quality, they look and feel like real stones, they are durable and very beautiful. I wear them often and my customers love them, all are drawn to the organic looking patterns and the colors; mainly pale aqua blue, soft cream with some reddish burgundy marbling. I love these stones because they remind me of the start of a summer sunset over the lake, a blue sky with some fluffy clouds that start to turn color from white to cream and little bits of red. The colors are so peaceful and joyful.
