"Cathy,  Thanks for checking, I did receive the crystals and they're gorgeous. I just love that big tabby quartz, it's amazing!  The other two crystals are very interesting and cute but that Tabby quartz blows me away every day.  I don't want to put it down. I want to hold it all day.  Thank you so much for sending me such a gorgeous Crystal and it was such a sweet surprise to have the other quartz crystals.  Thanks again."Renee S. - Bolton, CT

Wow,  I actually have a large beautiful quartz crystal from a crack in the earth in the middle of the California mother lode.  Love your photographic artwork, will you be selling photos to go with the specimens?  Let me know.  Thanks for sharing the history, will you be doing anymore publishing? Maybe a book?  So many questions.....  Thanks again,  Ernie & Family - New York, New York.

"Your Mother Lode California crystals are stunning in their esthetic appeal!  We are very happy with our order, it was easy, all crystals arrived intact.  We gave the Bonus crystal to our 12 year old son for a "Pet Rock."  Keep up your good work.  Many Thanks!" - Missy G. - Flint, MI.

"Cathy, it came this morning.  I could not have been more pleased.  They were magnificent!!  Even the small ones you added.  I will brag about them at our next Geology Club meeting.  Almost every collection has Arkansas and Brazilian Quartz but how many have equally excellent Sierra Nevada California Quartz crystals?  Not everyone! " - Tom in Little Rock, AR.

"The crystals are fabulous!  It's like snowflakes -- every one is a different design!.. Thanks so much!"

Cathy A. - Pueblo, CO.

"Thank you- the order arrived on time and was everything I expected. Thank you for the promptness and accuracy! I thought I had far more quartz in my collection than I could ever need until I read your article in Rock&Gem- that was a delight and it is wonderful to
see the educational efforts going on there." - Jeff N. - Colorado Springs, CO
