I bought this elongated teardrop turquoise cabachon from my friend, Andy Brown, this past June.  He mined it in Hachita in southern New Mexico.  I wasn't sure how I was going to use it, so I waited for an inspiration to come to me and this inverted design evolved.  I will have it for sale at the 2017 NC State Fair in the Village of Yesteryear, beginning on October 12th.
