1.26 Ct.Tw.Total Carat Weight Tanzanite Pair from Tanzania

This pair of cushion shape violetish blue tanzanites from Tanzania presents a technically refined matching set, each stone weighing 0.63 carats. The measured dimensions are 4.71 x 4.67 x 3.64 mm and 4.71 x 4.68 x 3.90 mm, indicating careful preforming and precise weight retention during cutting. Both stones are fashioned in a mixed brilliant cut, employing a brilliant facet geometry on the crown to promote strong table and crown brilliance, combined with a modified pavilion arrangement to enhance color saturation and directional scintillation. The medium color intensity is balanced for wearable brightness while preserving depth of violet blue tone, and the stones display the characteristic pleochroic tendencies of tanzanite with shifts toward violet and blue under varying angles of light. Clarity is graded as very very slightly included evaluated at eye level, which in practical terms means inclusions are minute and do not interrupt light performance or visual purity in typical jewelry settings. Polish is excellent across facets, the facet junctions are sharp and consistent, and symmetry is controlled to maintain optimal return of light, making these stones ideal for close matched pair applications such as stud earrings or pendant ensembles. Enhancement is heat treated, a stable and widely accepted practice applied to tanzanite to develop and stabilize the violet blue color, and this treatment is disclosed and consistent with industry standards.

The Natural Gemstone Company sources these tanzanites through established supply chains that emphasize eco friendly mining practices and traceable provenance. Mining partners in Tanzania utilize low impact extraction methods where feasible, including selective hand mining and controlled water management to minimize erosion and sediment runoff, and reclamation programs are supported to restore disturbed areas post extraction. Our sourcing model promotes fair labor practices and direct engagement with local communities, with a focus on transparent payments, safety training, and community development contributions that fund education and infrastructure. Each parcel is documented with chain of custody records, and independent verification is used periodically to confirm compliance with environmental guidelines and local regulations. For discerning buyers who value both technical gem quality and responsible sourcing, this matched pair offers calibrated proportions, consistent optical performance, and verifiable provenance from The Natural Gemstone Company.
