- La zigrasita és un mineral de la classe dels fosfats. Rep el seu nom de James Zigras, un col·leccionista de minerals que l'any 2005 va observar unes petites "boles" de color taronja sobre un exemplar verd d'elbaïta. William Simmons, de la Universitat de Nova Orleans, va determinar que era una nova espècie mineral, i el Dr. Frank Hawthorne, de la Universitat de Manitoba, va determinar la seva estructura cristal·lina l'any 2008.

- Zigrasite is a phosphate mineral with the chemical formula of MgZr(PO4)2(H2O)4. Zigrasite was discovered and is only known to occur in the Dunton Quarry at Oxford County, Maine. Zigrasite was specifically found in the giant 1972 gem tourmaline-bearing pocket at the Dunton Quarry. Zigrasite is named after James Zigras who originally discovered and brought the mineral to attention. (en)
