Schalenblende cab ~
Offered here is a cab of schalenblende, from Olkusz, Poland, something I'd never seen in cabochon form until I cut one a couple years back. I'm told the moniker is German, meaning "shell ore", and that its concentric-layered structure is composed of four minerals in distinct successive bands: The yellowish brown is wurtzite, the dark brown is sphalerite, the bright chrome is galena, and the brassy metallics are marcasite. Quite a mouthful! Rain and I liked it immediately for the strong contrast between its scalloped bands and areas of gleaming metals, and believe me when I say it's even more attractive in hand. After the striking pattern, you'll notice it's very VERY heavy, surprisingly so! Just awesome stuff, quite perfectly fascinating. This substantial cab has a very high rounded dome of 6.5mm, and despite a few teensy natural pinpoint voids and a couple of odd formation lines (NO cracks!), it has a fabulous polish on all sides.
Size: 38x25 mm
Weight: approximately 86 carats
