Well, to be honest, I was disappointed at how few chips actually had a gold glint in them.[Nuummite bracelets and necklace] Several had a distinctly blue flash that I recognize as Arfvedsonite. This is my first experience with your company, so, I don't have a frame of reference for your product. I have been collecting for almost 50 years and am confidant of my ability to distinguish signature characteristics that differentiate several similar species. You are recommended by Liz at healingcrystals, who I think Highly of and that is why I gave you a chance. Better luck next time? Angela Simms violet.flame@comcast.net
