Comment: Color, color, color, and 3*NOS (unheated, no window, no visible inclusions). This 'old' (all gems are old, or rather they don't age, unless abused) one carat of finest Ceylon sapphire was hand-cut in an individual oval shape, with a high crown, and thus a high table, and shield-like crown instead of the usual triangular facets and a bigger table. The result is a classic shape combined with an unusual appearance, oval yet with a different character, a variation which to identify even the trained eye needs a closer look, probably with lens. Speaking of which, after the lens comes into use, a few thick needle-like inclusions appear. Luckily, these sit vertical to the table and are thus not visible to the eye; although as so often, after a close-up study under the lens, some brains (not all, but probably the visually oriented types) tend to add or fill-in, even from a normal viewpoint, what the eye had previously seen only under the lens. Hence, for this gem, as an outstanding e-ring stone, with THE perfect blue, it is advisable simply to leave the lens aside and enjoy the perfect color and its lively luster. Why burden beauty with knowledge when it causes suffering? Let us set it for you, using its cut to your advantage with an equally lower profile in the ring's gallery. See the side image to get a better idea of the, relatively, bigger crown and smaller pavilion. In this case it makes for a bigger face-up with a smaller table. 

P.S. This is a stone from our old Sri Lanka times, bought by a customer with (those days) developed 'Gem-Shares', which is, now, almost a decade later coming back to enjoy the premium. Before somebody asks: I will not disclose the former price.
