These historic chrysoberyl specimens were collected in the 1940s-1950s and remain true mineral classics of the Golden Era of Brazilian gem crystals. They are few and far between today. This cluster of sharp crystals has excellent color, superb glassy luster, and a depth of saturation we do not often see. It is sharp, not rolled or damaged as so many were, from the way they were carelessly collected and handled in the time (an era when they were essentially considered gem rough, and people did not handle gem crystals so delicately as today). This actually is probably half of a cyclic sixling twin, stood upright so one tip stands up, with a small twinned sixling (just over 1 cm) standing edge-on to the viewer, right in the middle; and another crystal coming in from the left. So, while the display view does not show a twin face, it is compelling and dramatic for all the crystal points coming out at you - and of course, the color and luster. This is from the original thumbnail collection of the great Willard Perkin, inventor of the standard thumbnail display box (Perky Box) and is complete his tiny identification label, which was carefully typed out on a typewriter then photographed at a scale which would allow it to fit in the thumbnail box. The specimen was thoughtfully selected by Rock Currier as part of his payment for the appraisal of Willard Perkin's private TN collection before it was released for sale by Jim Minette. Rock Currier Collection #6748, where it has been since 1999.
