The Mahenge region, revealed in 2007 by the discovery of enormous spinel crystals, today produces some of the most sought-after spinels on the market.\u003c\/p\u003e\n\u003cp\u003eIts colour — “pink-orange” according to GRS, “reddish pink” with intense saturation according to Lotus Gemology — is entirely natural: the stone has undergone no thermal treatment, as confirmed by its two certificates, both with a Tanzania origin determination. GRS has furthermore awarded it the “vibrant” brilliancy designation (see certificate appendix), reserved for gemstones cut to their optimal proportions for a maximised colour-reflection pattern.\u003c\/p\u003e\n\u003ch3\u003eCharacteristics\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eStone:\u003c\/strong\u003e Natural spinel\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 6.10 carats\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eColour:\u003c\/strong\u003e Pinkish orange (Lotus: “reddish pink”, intense saturation; GRS: “pink-orange”, brilliancy-type “vibrant”)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eShape:\u003c\/strong\u003e Antique cushion, brilliant\/step cut\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 12.08 × 9.27 × 6.41 mm\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e Unheated — no treatment\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e Tanzania (Mahenge)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCertificates:\u003c\/strong\u003e Lotus Gemology (No. 7838-2275) and GRS GemResearch Swisslab (GRS2026-070514, with “vibrant” appendix)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe stone is delivered with both original certificates.
