The Rogerley Mine has produced what many people consider to be the finest green fluorites, certainly the finest lustrous green fluorites. Recent work at this classic locality from about 2000-2010, and ongoing slowly, has generated tons of material for the market. However, of that tonnage, only a very small percentage has been top grade - probably only in the hundreds of pieces or less, over the whole decade or so of mining. Most large plates have a varied surface in quality, while this is lustrous an dbright, with top color and sparkle throughout. This particular plate was sold by one of the mine partners, Cal Graeber, to Dr. Ed David in 2005. It is a well-trimmed plate with good aesthetics, very even and high quality luster throughout, and with large crystals to 3 cm, many of which are penetration-twinned. There is some very minor damage, just a few small chips here or there - on a plate of this size and quality overall, considered acceptable. This dramatic large plate can be displayed at just about any angle to emphasize either the more isolated twins standing at the periphery, or to emphasize sheer size/breadth of color. It is simply a personal choice of style, as to which you prefer more. These fluorites are also highly fluorescent, as seen in the photos which show them glowing "day-glow" purple under ultraviolet light. Joe Budd photos.
