Vintage Green Rhyolite Rainforest Jasper Big Oval Goldtone Pendant Necklace

In very good clean condition. Chain measures approximately 17″. Pendant measures approximately 1.75×2.5″. I am not certain if the stone is Rhyolite or Rainforest Jasper but it registers among the jade category for hardness when tested . It has beautiful and varied inclusions. Warm goldtone hardware. The jump ring on Pendant looks like it has been repaired or added to accommodate the chain( see pic) but I have left it as is for historical integrity. It can be easily replaced .
