Comment: Aquamarine with very little green, almost a pure light sky blue. As visible on images the gem has a a window. Fortunately it is clean and liquid, hence the center is pleasantly un-intrusive. As member of the beryl family, enduring and suitable for jewelry. As always in untreated aqua the hue is bright and shiny (as well presented in images), gleaming in the sun and tungsten light. With 10x15mm big face up even for 6+ carats, the usual trade-off for a window. No ring sizes under 5, very much a pendant stone, or with a brother/sister as flashy earrings. Ask us for a matching pair. Liquid crystal. Cutting grade 'good' refers only to window, not to quality of facets, polish or symmetry (nothing less than 'very good' there). Inclusions only under the lens, and then for sharp eyes only.
