21.24 ct Oval Tanzanite Gemstone – GIA Certified Tanzanite - VB 6/6

An exceptional 21.24 carat oval tanzanite of commanding presence and remarkable depth of color. This is a true statement stone — large enough to fully express the rich, velvety saturation that only fine tanzanite above 5 carats can achieve. GIA certified, confirming its identity as natural tanzanite, this gemstone displays a deeply saturated blue-dominant hue with flashes of violet under changing light — the signature pleochroism that defines top-tier material. This stone sits within the highest color range and would be classified as VB 6/6 using gemological grading standards, or AAA+ / Heirloom quality in retail terminology — representing the finest top 1% of all tanzanite production. Added peace of mind is provided through the additional security of an accompanying GIA certificate. A rare, investment-level tanzanite gemstone with both size and colour working perfectly together.
