The details
Deep blue color carries this loose emerald cut sapphire, a single natural stone, heat-treated, with long step facets and a clean octagon outline. It is sold on its own, without any metal or setting. The step cut gives a glassy, mirror-like look rather than a sparkle, so the color does the talking. You can have it set in a ring, a pendant or earrings, depending on the piece you imagine. Picture it in a slim band for everyday wear, or in a bolder cocktail ring for evenings out. A fitting choice for anyone born in September. A stone with presence.

Perfect For
