This stunning and big octohedral diamond crystal is a significant example for the locality, and it is compete all around. It is equant, well-formed, on all sides. The color is a rich champagne hue with good "life" to it, as opposed to many Argyll stones which can be somewhat more brown. The luster is superb - a classic and silky "adamantine" luster that is hard to describe until you actually see it. The very word adamantine was actually coined from the luster of a fine diamond, in fact. This crystal is translucent to transparent throughout, with some veils inside, and weighs 10.28 carats. It has been a long time since I have had such a large and gemmy diamond at this price point - normally they go through a few more hands to reach market, than this one did. I bought the only two large ones available to me in this price range, whereas normally they would have been perhaps twice this cost, even to me.
