Leopard Nebula Leopard skin Agate: Brazil produces the majority of the agate mined in the world bringing all types and colors to the market. This is a good example of the many varieties that occur in this region. Although this is from Brazil it bears the name following its appearance. Once might think this is a skin of an animal rather than an Agate. The painting had morphed into what appeared to be an “outer space” theme, and since a Leopard Nebula exists, it was only natural to name it as such. To be sure, the eventual owner of this piece will have fun tracking people as to what it really is.
