1.21 Ct. Bluish Green Sapphire from Tanzania

One beautiful transparent 1.21 carat oval bluish green sapphire, measuring 6.38 by 5.61 by 3.81 millimeters, presents a refined combination of color, proportion, and workmanship that will appeal to technically minded gem buyers, The Natural Sapphire Company. This sapphire is cut to a mixed brilliant style, combining a faceted brilliant crown with a modified pavilion, a choice that maximizes both color saturation and scintillation in a stone of this size. The face up color reads as a true bluish green with intense color intensity, demonstrating strong saturation without appearing overly dark, and the excellent polish across all facet planes enhances the stone s transparency and light return. Evaluated at eye level the clarity grade is slightly included, a classification that balances natural character with pleasing visual performance, and most importantly this sapphire is completely free of enhancement, an untreated natural gem from Tanzania, a provenance that confers additional interest to connoisseurs.

From a cutting and proportion perspective this oval sapphire is engineered for optimal balance between spread and depth. The pavilion depth of 3.81 millimeters relative to the average of the length and width yields a well proportioned depth percentage in the low sixties percent range, a dimensional relationship that supports lively internal reflection while preserving a generous face up presence. The mixed brilliant cut strategy places smaller brilliant facets on the crown to create a lively play of light across the table, while the pavilion employs larger modified facets that channel return light into the crown, intensifying the bluish green tone as the gem is moved under illumination. Facet junctions are crisp and symmetrical, a sign of skilled lapidary control, and the excellent polish promotes crisp facet contrast and bright scintillation. The oval outline is slightly elongated, which increases perceived size on the finger and offers pleasing orientation for traditional settings, while the table facet proportions and crown height maintain a balance that keeps the stone vivid and lively in both natural and artificial light.

Clarity in this sapphire is described as slightly included when viewed at eye level, a practical and honest grade for natural sapphires, and it reflects inclusions that are small enough to preserve overall transparency and brilliance, yet present enough to confirm natural origin to an experienced viewer. Typical inclusion types in sapphires from this region include minute crystals and faint rutile silk, which can act to soften light and sometimes enhance the apparent depth of color, however this specific gem displays clean face up appearance with only modest internal features that do not compromise structural integrity. The absence of any heat or clarity enhancement further underscores the rarity and desirability of the stone, because historically sapphires have been prized in their natural state for ceremonial and sovereign use, worn by royalty and clergy as emblems of wisdom and protection. Tanzanian sapphires have been historically used both locally and in international trade for finely crafted jewelry, and collectors who value provenance will appreciate that this untreated Tanzanian stone retains not only geological authenticity but also the tactile and visual qualities that have made sapphires objects of reverence across cultures.

In practical use this 1.21 carat oval sapphire is well suited to a central solitaire or halo mounting, where the generous face up area and intense bluish green color will be showcased, and the stone s dimensions allow for versatile settings in yellow gold to enhance the warmer green tones, or in platinum or white gold to emphasize the cooler blue aspects of the color. For buyers who prioritize light performance, orienting the oval s length along the finger enhances the perceived size and showcases the mixed brilliant cut s scintillation, while a low profile bezel can protect the girdle during daily wear without sacrificing visual impact. Because the gem is untreated, routine care is straightforward, warm soapy water and a soft brush maintain surface cleanliness, and professional ultrasonic cleaning is acceptable for most natural sapphires but should be confirmed based on inclusion visibility before use.

This Tanzanian bluish green sapphire offers a combination of technical excellence, natural heritage, and collector appeal, presented by The Natural Sapphire Company for those who appreciate the nuances of cut, color, and craftsmanship.
