As you may already know, Rue had this little faux-alligator travel case that she filled with loose gemstones – she often purchased stones and then had them made into one-of-a-kind jewelry pieces (and just for the record, how fabulous is that?). Anyway, this particular rock is either a citrine or – the rarest Imperial topaz. If it is the former, it is known as the “Lucky Merchants Stone” and is to be put in a cash register for amazing results, and is used for healing problems with digestion, diabetes, constipation and depression – none of which Rue had, so maybe it worked. If it is the later, then we are letting a stone worth a fortune go for next to nothing (which, believe it or not, Rue would love!). The boulder is over half and inch long and about 3/8″ wide. Comes with a Certificate of Authenticity from Estate of Rue.
