UPDATED! Kay Robertson Collection
I will say that, in a world full of characters and crazy collectors, Kay stands out as one of the most passionate collectors I have had the privilege to know – to this day, at 97, she is as passionate about minerals and the glory of knowledge that comes from them, as she must have been 90 years ago when she started.
In April 2017 we packed up her collection to share these treasures with a new era of collectors while Rob had a chance to visit with her and hear stories of some of her pieces. Read some of Dr. Rob Lavinsky's favorite experiences with her in our blog entry featuring Kay.
