20+ct Holley Blue Agate pendant in 925 Sterling Silver wrap

This is the Holy Grail of agate.  Oregon Holley Blue. Take a look at that incredible jelly blue material.
Holley Blue is only found now in private collections because the place where it used to be collected is now private property, and nobody can get at it anymore. 
I decided to keep some of the white and brown matrix on the stone and a natural shape.  Wrapped in 925 silver wire. I'm selling this on an adjustable 16-18" silver chain.
