This is a relatively large, very GEMMY AND TRANSLUCENT twinned crystal of chryoberyl, of incredibly sharp form! Most chrysoberyls twin as sixlings and thus have multiple terminations that, to me, distract the eye. This specimen, however, exhibits another form entirely, with the "ingrown" twinning resulting in a sharp crystal form without the usual flanges, to me much more appealing and symmetrical. The "classic" twins are on a different axis of the crystal growth, as well, and so the shape is totally different from this style which is actually more rare. This twinning allows for more sharp hexagonal form to be preserved, and they tend to be more gemmy. I am told these came out in the early 1970s. It has high luster, and better transparency in person than reflected here: really quite transPARENT in 2/3 and translucent in the rest. The crystal is complete save only the contacted bottom edge. Also, it has a beautiful golden-cognac color that GLOWS when backlit a bit more than we did for the photos. You can get the idea, I think.
