A single rhombic crystal to 0.2mm. Menezesite crystallizes in the isometric system and by viewing this specimen under a microscope you will see a fine, perfect crystal, with diamond shaped faces. It is associated with Clinohumite.
Bill and Ann Cook purchased this specimen from Luiz Menezesite probably 4 or 5 years prior to his death. Luiz was a fine mineraolgist and expert in Brazilian mineralogy. Luiz personally collected the material in the 1970's from in the dolomitic carbonatite of the Jacupiranga mine, which would later be named in his honor. Zirkelite was discovered at this locality in 1895 and then Quintinite was discovered in 1997. The paper on Menezesite can be seen here; CLICK
Please see the signed label from Luiz in the prov. tab.
