Dendritic Patterns
Smudges do not count! Dendritic patterns must show a clear fern or tree like pattern.
For more information on dendrites and much, much more, Lynne Wheeler highly recommends:
Collecting Rocks, Gems and Minerals
by Patti Polk
ISBN-13:978-1-4402-0415-90
Lynne has found this to be an excellent resource for all rockhounds, especially in Arizona.
Sonoranite — The World’s Newest Gemstone
While in Tucson last week members Lynne Wheeler and Peggy Randall had a fascinating conversation with the folks at https://sonoranite.com
You can see from the photo that Lynne took and from the gorgeous jewelry shown on the Sonoranite website, this Arizona desert gemstone is an incredible find!
