from the Mineral of the Month Club: "We first saw these strange-looking specimens (also spelled "melicaria") at a show last fall, a new find from Mexico. From what little information that was available, it seems they are "a quartz cast after the crack-filling of a septarian nodule or possibly after a similar crack-filling spherulite," according to former Smithsonian curator John S. White." This HAPPENS to be an actual John S. White specimen, with his label accompanying it! It is an absolutely fascinating-looking specimen, like a fossil of some strange early life form. It is complete and undamaged all around. White''s label says this Melikaria is calcite rather than quartz. Ex Lewadny collection 8.2 x 6.8 x 6.2 cm
