34.74 Ct.Tw.Total Carat Weight Cabochon Tanzanite Pair from Tanzania

This matched pair of oval tanzanite cabochons presents technical refinement in both rough selection and lapidary execution, each gemstone weighing 17.21 carats and 17.53 carats respectively, with dimensions of 19.68 x 12.67 x 8.09 millimeters and 19.66 x 12.55 x 8.07 millimeters. The stones are cabochon cut to a domed oval profile, with robust crown height that fills the silhouette and minimizes windowing while maximizing color depth. Clarity is graded included at eye level, which in these pieces contributes to internal texture and subtle light diffusion rather than detracting from overall appearance, because the cutting preserves translucency and centers inclusions away from the visual axis. Color intensity is classified as intense violet, and heat treatment has been applied to enhance the removal of brownish zoning and to stabilize the dominant trichroic tones. Technical gemological parameters of tanzanite relevant to the cut are a refractive index range near 1.691 to 1.700 and birefringence that can be detected in faceted material, and the cabochon approach here is chosen deliberately to emphasize saturated hue and internal glow rather than facet scintillation. Origin is Tanzania, and provenance was considered when pairing to achieve close matches in hue, saturation, and size for use as a coordinated set.

The lapidary craftsmanship executed by The Natural Gemstone Company emphasizes surface finish and dome symmetry, with an excellent polish that yields a high luster and clean specular highlights across the domes. Because these are cabochons, the light display is governed by transmission and internal reflection rather than facet return, producing a soft, even luminosity and a velvety interplay of violet tones as the stones are rotated under light. The domes are carefully centered to present consistent color across the length and width, and the polish level minimizes surface diffusion so that the intense color carries through to depth, resulting in a saturated, three dimensional appearance. For design applications where color dominance and paired symmetry are paramount, such as matched drop earrings or a pendant and brooch combination, these tanzanites provide both technical consistency and aesthetic presence, with heat stabilization ensuring long term color stability and cabochon geometry delivering a controlled, immersive light performance.
