The softness of anglesite makes it challenging to cut, so stones are rare collector's items and in this size all the more so. This is a fantastic and very large example of rich, lemon-yellow color from the best locality in the world for the species (with finds mostly from 20-30 years ago). The oval portuguese cut has been faceted to proper angles, a challenge to even top cutters. So it has a wonderful brightness you do not often see in anglesite cut stones. This is thus a hard to replace rarity suitable for a museum collection or connoisseur displayof rare cut gems. It is not wearable due to its hardness, though. This source crystal was brought out in the 1970s and was eventually sold for cutting. It was custom cut by Spectrum-Award winner Mark Kaufman.
