2.06 Ct. Blue Sapphire from Tanzania

This 2.06 carat transparent oval blue sapphire from Tanzania presents a finely calibrated mixed brilliant cut, with dimensions 8.62 by 6.45 by 4.40 mm, vivid color intensity, a clarity grade of slightly included at eye level, excellent polish, and no enhancement, and it is offered by The Natural Sapphire Company. The mixed brilliant faceting scheme combines a brilliant cut crown, optimized for scintillation and light return, with a more pavilion oriented design that controls color saturation and directional light leakage. The pavilion depth relative to the table and crown angles has been shaped to balance face up size with internal reflection, producing an oval silhouette that maximizes blue saturation while maintaining lively facet contrast. Facet junctions are crisp and the polish is executed to a high standard, so light transitions across the crown facets are clean, micro reflections are minimized, and the gem shows consistent luster across orientations.

Optically this sapphire displays a strong interplay of brilliance, scintillation, and body color, influenced by the mixed brilliant geometry and the stone s natural pleochroic behavior. In natural daylight, which contains a full spectrum of wavelengths, the gem reads as a deep royal blue with vivid saturation, while flashes of violet and slightly purplish tones are visible at oblique angles due to pleochroism and the stone s internal color zoning. Under warm incandescent light the relative increase in red wavelengths softens the blue slightly, rendering a rich, velvety appearance with more apparent depth and fewer high contrast flashes. Under cool white LED lighting the higher blue content in the source emphasizes the stone s vivid intensity, producing more energetic scintillation and a slightly brighter face up appearance. The mixed brilliant cut generates small, bright scintillation flashlets from the crown facets when the gem is moved, and the excellent polish ensures these flashes are sharp, not dulled by surface graining.

The clarity profile, recorded as slightly included at eye level, means inclusions are present but do not materially disrupt the overall transparency or the gem s light return in typical mounting scenarios. These inclusions are consistent with natural Tanzanian corundum, and under loupe or microscope they will appear as small crystals or silk like needles, sometimes contributing to the stone s overall silkiness and depth. Because no enhancement has been applied, the color and inclusion state are natural, and the corundum s intrinsic hardness of 9 on the Mohs scale makes this sapphire highly suitable for ring settings and daily wear. For mounting, orienting the oval with the long axis parallel to the finger enhances perceived size, while an open gallery setting or bezel with subtle light passages will allow the pavilion facets to communicate with ambient light and preserve the gem s vivid tone, versus a closed back that can deepen color but reduce sparkle.

From a design and technical perspective this 2.06 carat Tanzanian sapphire is ideal for collectors and jewelers who prioritize natural color integrity and precise cutting. The mixed brilliant cut provides a controlled balance between color concentration and brilliance, the excellent polish preserves crisp facet reflections, and the eye level slightly included clarity maintains transparency without optical masking. When evaluating this stone under various lighting conditions, expect a deep saturated blue in diffuse daylight, a richer and warmer blue under incandescent sources, and intensified electric blue highlights under cool LEDs, with consistent scintillation due to well matched facet proportions. The Natural Sapphire Company stands behind the provenance and craftsmanship of this gem, and our technical team can advise on mounting choices that will best showcase the stone s vivid color intensity and mixed brilliant light performance.
