One of my favorite semi-precious gemstones is jasper. I think because it always brings to mind this verse from the bible - Revelation 21:18. 'And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass'. Imagine that city - New Jerusalem. Don't you know God has reserved the very best for that city; jasper so beautiful our poor earthly eyes could not stand the sight.
I also love jasper because of all the wonderful variations and the pictures I imagine I can see in it. Most of all, I love it because it cannot be re-created by man. Just look at this wonderful piece I found a few weeks ago. What do you see?
