2.13 Ct. Green Sapphire from Tanzania

One beautiful transparent two point one three carat oval shape green sapphire, measuring eight point five five by six point three nine by four point three zero millimeters, presents a rare combination of size, color, and clarity. Cut as a mixed brilliant, the pavilion is faceted to maximize light return while the crown facets retain an elegant table for surface luster, and the overall proportions yield lively scintillation across the oval silhouette. The gem is graded very slightly included when evaluated at eye level, which means the inclusions are minimal and do not detract from the face up appeal, and the excellent polish on every facet plane ensures crisp reflections and sharp facet junctions. Color intensity is described as intense, with a rich green character that shows nuanced tones as the gem moves under different lighting, and the piece is completely untreated, with no enhancement, making it a natural and honest example of what Tanzanian corundum can offer. The provenance from Tanzania is meaningful to an educated buyer, because this region has produced some of the most interesting and collectible green and parti sapphires in recent years, and documented origin contributes to both the storytelling and the long term desirability of the stone.

From a gemological perspective this sapphire stands out for a number of reasons that affect value and long term performance. Sapphires are composed of corundum, one of the hardest natural gem materials second only to diamond, and this durability means that a well set sapphire will withstand daily wear without undue surface damage. The clarity grade very slightly included suggests that internal features are present but limited to minor mineral crystals or growth characteristics that do not significantly interrupt the passage of light, and these features often serve as natural fingerprint evidence of origin. The intense color intensity is especially important in green sapphires because saturation at this weight and size is relatively uncommon. The fact that this gem is not heat treated or otherwise enhanced elevates its appeal to collectors and connoisseurs who value natural color and the geological story behind the tone. Excellent polish and a carefully executed mixed brilliant cut further enhance the gem by delivering both brightness and face up color stability, which are key attributes that knowledgeable buyers look for when assessing potential investment quality or heirloom status.

When considering custom design, this green sapphire is exceptionally versatile and plays beautifully with a range of complementary gemstones and metals. For a classic and luminous approach, a halo of small white diamonds will amplify brightness and provide a high contrast backdrop that makes the green pop, while tapered baguette diamonds on the shoulders offer a sophisticated Art Deco aesthetic without competing with the central oval. If you prefer color harmony, consider pairing this stone with small teal blue or bluish green sapphires to create a monochromatic palette that emphasizes depth and subtle shift in tone. For striking contrast, warm yellow sapphires or champagne colored diamonds will energize the green and bring out any yellow overtones, creating a lively, vintage inspired composition. Green sapphires also pair very well with minty green gemstones such as pale tourmaline or light green garnet for a botanical palette, and small accent stones can be used to guide the eye and enhance perceived size without overwhelming the main gem. In terms of metal, white metals such as platinum or white gold will emphasize the cooler forest aspects of the green, while yellow gold will warm the hue and lend a classic, luxurious character to the piece.

Design and setting choices will influence how this sapphire reads on the finger and how it performs in daily wear, and The Natural Sapphire Company can guide you through those decisions to create a piece that balances beauty, security, and longevity. For maximum light return and a traditional solitaire presence, a four prong setting that secures the corners of the oval allows the crown to reveal its full brilliance while keeping the profile refined. For greater protection and a more contemporary look, a bezel can hide the girdle and offer excellent edge security, while a low profile setting will sit comfortably for everyday wear. Consider orienting the oval in an east west alignment if you desire a modern twist, or keep the conventional north south set for timeless symmetry. Band design can incorporate pave diamonds to visually enlarge the center stone, or simple split shoulders to add presence without detracting from the color. Care instructions are straightforward, because corundum is very hard and resists scratching, however periodic professional cleaning and occasional inspections of prongs or bezel walls will preserve the stone and setting.
