Comment: This near five carats cabochon stands out with its fine color. The deep, pure green is a rare occurrence in Zambian emerald, no yellow, no blue, no dulling grey, never pale or dark. Some white sugar-like crystal inclusions reach the surface on a fifth of the outer edge, mostly invisible in a bezel setting. Cabochons are tougher for daily wear and tear and therefore make better ring-stones than faceted gems (all emeralds are on the soft side). Compare this gem with the eight carat: a richer hue, without any blue, darker toned, resulting in a totally different type of emerald. The flat under-side (see 'more images') lowers its weight, while keeping almost the same face-up, but makes a potential setting-profile less prone to get smacked around. Colorless-surface-oil only, no plastic fillers, or colored glues, and no beryl powder burned into green colored paste and then called eternity emeralds. Note that the skin-color in the hand-shot does not lighten the green as is common in cabochons. There, between 10 and 11 o'clock, you can also detect the white surface-crystal mentioned before. Rare color quality in a full size emerald, an luxurious gem for a massive (gents) platinum ring or a starting point to design a delicate brooch or pendant.
P.S. Normally, pros don't like to describe one gem with the color of another, but since the images do not transfer it at all, allow me an exception: this emerald's tone and hue is just like what we'd expect from imperial jade, not the touch and crystal and the hundred other features that make imperial jade so special, but only the color, that is just like fine imperial jade, opaque of course.
