Thank you for entertaining my musings.  Unfortunately, I must decline your offer.
I could consider branch fossil sections to offset small pieces with fire but the suggested offer price for all as is not doable for me.
But again, thank you for the correspondence and accurate descriptions.
Best regards,
Marshall

 

From the pictures I only see a very small percentage of anything with fire/color.  As you know it is very unlikely anything without showing a trace will produce a color piece.  My display must show at least a majority of color although not necessarily harlequin fire.  You are being very upfront showing as many pictures as you did and I appreciate that fact.  That being said, I will take another look tomorrow and estimate what is usable and offer a corresponding price per gram overall and another with high grading.

 

Are there any tree branch sections?  With or without fire?
Thanks,

 

What could I offer without insulting you?
Agree Virgin Valley is for specimens not cutting.  I fear the same is true for the Ethiopian although time will tell.
Regards,
