💍 Love this stone? We can have it custom-mounted by our partner jeweler.

Natural red spinel from Tanzania weighing 9.08 carats, cut in a cushion shape (brilliant crown, step-cut pavilion). An exceptional stone by its weight — unheated red spinels above 5 carats are rare, and beyond 9 carats they become true collector's stones.

Its vivid red colour is entirely natural: the stone has undergone no thermal treatment, as confirmed by its two certificates. The GFCO laboratory describes it as "vivid pinkish-red", the GRS laboratory as "orangy-red" — two readings of the same intense, luminous red.
