Why Mahenge spinel matters

Evaluate each Mahenge spinel on its documented colour, clarity, cut, carat weight, treatment disclosure, and laboratory report.

Five-step evaluation

(1) GIA report confirms variety = spinel, origin = Tanzania (Mahenge where supported), treatment = none; (2) colour reads vivid hot pink to neon-red with strong saturation; (3) clarity is eye-clean to lightly included; (4) cut returns light through the centre — Mahenge rewards a precise cut; (5) carat weight matches the lab.
