Greyish Blue Spinel - 1.24ct Emerald Cut - Natural Ceylon Spinel

It means the greyish blue on your screen is the colour the stone had when it came out of the ground, with no heat applied to change it. We list the treatment as unheated and the certificate reference on this page lets you check that against the report. Heated spinel is a normal part of the trade, but an unheated stone gives you a colour nobody has altered.

It is a description. It tells you the blue carries a soft grey component, so the stone reads subdued and steely rather than bright or electric. There is no grading scale behind the name, so we recommend judging the colour from the photographs and the stone's character rather than from the label.

Face up it is a slim rectangle, about 7 mm long and 5 mm wide, so the length is roughly one and a half times the width. The 3.81 mm depth gives it enough body for its 1.24 carats without making it sit tall. It will read as long and clean-lined rather than broad.

Very Good is the cut grade recorded in the specifications for this stone. In an emerald cut, the long step facets act like windows, so they show the stone's colour and the slight inclusions plainly rather than hiding them behind sparkle. We see that as part of the appeal of a step cut on a natural, unheated spinel.

Yes. We bought it as rough weighing 3.515 ct, and our founder photographed the work along the way, six photographs in all, including one of the rough. The finished weight is 1.24 ct, so the stone you see is the result of cutting that rough down into a finished emerald cut.
