2.31 Ct. Blue Tanzanite from Tanzania

This is an exceptional 2.31 carat, cushion shape, blue tanzanite from Tanzania, offered with pride by The Natural Gemstone Company, and it stands out at once when compared to the more common commercial options on the market. At 9.01 by 6.86 by 4.52 millimeters this gem occupies a size category that is distinctly rare for blue tanzanites that are both transparent and well cut, and the combination of carat weight and clarity in this piece is a level of rarity that you will seldom find in ready to set stones. Many tanzanites available at similar or lower prices are smaller in face up size, or they show more body color that affects brilliance, or they are heavily included which diminishes light return. This gem instead offers a clean, luminous window into tanzanite color, and the mixed brilliant cut has been executed to maximize sparkle while maintaining a classic cushion silhouette, making it a superior choice for a single stone ring, a pendant, or a bespoke piece that demands presence without the need for compensating accent stones.

Color is where this stone asserts its real rarity, the tone reads as a delicate and pure blue with light color intensity, and it reveals a play between soft cornflower and cool ocean blue that is less often seen in stones of this size. On the market you will frequently encounter tanzanites that are either heavily violet leaning, which can appear darker and less versatile in different metal colors, or stones that are stronger in color but so deep that they do not exhibit the lighter airy blue that photographs and many designs favor. This gem strikes a unique balance, it reads blue rather than violet, yet it retains enough saturation to show a satisfying color face up, and the light intensity allows excellent light return, giving it a lively, almost gemmy sparkle that flat, dark stones lack. Clarity is graded as very very slightly included, evaluated at eye level, which effectively means the stone is eye clean in everyday wear, a level of clarity that is particularly collectible at this carat weight compared to many similar sized or larger stones which often carry more obvious internal character when viewed without magnification.

Cut and polish are the practical details that translate rarity into real world beauty, and this cushion is cut with a mixed brilliant facet arrangement to bring the best of both worlds, the scintillation of brilliant facets together with the softer, larger planes that flatter the overall silhouette. The excellent polish enhances every facet junction, so light moves through the gem with minimal obstruction, producing lively flashes across the table and crown, and the pavilion depth and facet proportions have been tailored to the given dimensions so that the stone presents a generous face up area relative to its weight. Compared to standard step cut cushions or poorly proportioned commercial cuts, this mixed brilliant cut delivers a more modern, lively presence, while conserving the cushion shape that many buyers prefer for its timeless elegance. The proportions at 9.01 by 6.86 by 4.52 millimeters make this stone versatile for a variety of settings, it sits comfortably atop a ring cup without appearing top heavy, and it translates well into solitaire and halo designs alike for those who seek a balanced and refined aesthetic.

From a value perspective this tanzanite offers advantages that are difficult to match in the current market, the combination of 2.31 carat weight, eye clean clarity, transparent body, and an uncommon pure blue hue elevates it beyond mass market material. The stone has been heat treated, a stable and widely accepted enhancement that improves the desirable blue tone, and given its Tanzanian origin the gem carries the provenance collectors appreciate, because quality tanzanite is almost exclusively sourced from a limited region which adds to its collectible appeal. When you compare the price per carat of ordinary commercial tanzanites that lack one or more of these attributes, this cushion becomes a compelling investment for anyone seeking a stone that will perform brilliantly in jewelry and retain its desirability over time. The Natural Gemstone Company stands behind the descriptions we provide, and we encourage prospective buyers to request detailed imagery and to discuss mounting options, because a stone of this caliber benefits from considered design to showcase its best attributes.
