5.37 Carat GIA Certified Tanzanite – Investment Grade AAA+ / Heirloom Quality

A beautifully balanced 5.37 carat oval tanzanite, combining exceptional depth of color with strong brilliance and excellent life. At over five carats, this gemstone has the presence and richer saturation sought by collectors looking for a fine, GIA-certified tanzanite.

The accompanying GIA Gemological Report independently confirms the gemstone as natural tanzanite and describes its color as violetish blue — a predominantly blue body color with flashes of violet as the stone moves through different lighting.

We classify this gemstone as vB 6/6, equivalent within our grading system to AAA+ / Heirloom quality. Stones of this caliber represent the finest approximately 1% of the tanzanite we select, with the combination of saturation, clarity, cut and brilliance we look for in exceptional tanzanite.

For clients searching for an investment-grade tanzanite, this is precisely the type of gemstone we recommend: substantial size, outstanding color, excellent brilliance and independent GIA certification.

An elegant, highly desirable 5+ carat tanzanite and a superb example of the finest material this increasingly rare gemstone can produce.
