Title: Mystery Rock
Post by: iamrockaholic on August 18, 2018, 09:18:15 PM

Hi again my new friends.  I need help again.  A couple of years ago we purchased this "Mystery Rock" and can't remember where we got it (either Colorado or NC shows.  To boot, I can't find the identification I usually put on our purchases.  My hubby just got around to cutting it and I still can't identify it.  The entire outer surface was white and the white inside looks "chalky".  Its mostly white, tan and brown with some blue in the striations.  One or two have crystal pockets.  There is no translucency.  Any suggestions would be greatly appreciated.

Also, I forgot to thank you for your help with my Exotica Porcelain Jasper.  Thank you.

Thank you both.  You are exactly right.  The "chalkiness" and so much white threw me off.   THANK YOU!!!
