2.16 Ct. Bluish Green Sapphire from Tanzania

This 2.16 carat oval bluish green sapphire from Tanzania presents a technically refined combination of material quality and lapidary precision, offered by The Natural Sapphire Company. The stone measures 8.34 x 7.04 x 4.86 mm, and has been fashioned in a mixed brilliant cut, integrating a faceted crown with brilliant style facets and a pavilion that retains step elements to control light return and color saturation. The cutter maintained disciplined proportions to maximize face up brilliance while preserving weight, resulting in a gem that reads vivid in color intensity, with a transparent body and well managed pleochroic tendencies between blue and green under varying light. Clarity is graded as very slightly included when evaluated at eye level, indicating that internal features are minimal and do not impede optical performance. The polish is excellent, producing crisp facet junctions and smooth facet planes that enhance scintillation and allow accurate assessment of hue and saturation. The sapphire has been heat treated, a stable and widely accepted enhancement, applied to optimize tone and color uniformity without compromising the stone structure.

From an investment perspective this sapphire combines attributes that support future appreciation, technical rarity, and market desirability. Stones above two carats with vivid saturation, good transparency, and minimal eye visible inclusions occupy a smaller segment of supply, particularly from responsible Tanzanian sources, and collectors increasingly prize traceable origin and documented treatments. The mixed brilliant cut is favorable for resale, since it presents strong light performance in multiple mounting styles, and the excellent polish and proportional cutting enhance marketability. Heat treatment is common and acceptable in the trade, and while untreated stones command premiums, well executed heat treated material with transparent body and vivid color remains highly liquid. Portfolio considerations include scale scarcity for similar sized material, growing demand for colored gemstones as alternatives to traditional assets, and the reputational advantage of provenance and certification provided by The Natural Sapphire Company. For clients seeking a technically superior, aesthetically compelling, and commercially robust sapphire, this 2.16 carat oval is positioned to retain collector interest and potential appreciation over time.
