Aventurine and Jasper

I bought these strands as you see them from A Grain of Sand and all I had to do was string them on Soft Flex and add a pretty clasp, also from A Grain of Sand.  The strand on the left is green Aventurine and the one on the right is Jasper.  Strung on Sterling Silver Extreme 925 Flex Soft Flex Metallic Flex Wire, Medium (0.019 in diameter).
