1.17 Ct. Yellowish Green Sapphire from Tanzania

This is a transparent 1.17 carat oval yellowish green sapphire, whose exact dimensions are 6.69 by 5.82 by 3.41 millimeters, cut in a mixed brilliant faceting style, with an evaluated clarity grade of very slightly included at eye level, intense color intensity, and an excellent polish. This stone is offered by The Natural Sapphire Company, and it is notable in the market for the combination of its clean face up appearance, natural, no enhancement status, and the uncommon yellowish green hue that reads both fresh and sophisticated. The mixed brilliant cut gives the sapphire strong scintillation and a lively display of light across the table, while the oval outline provides a flattering face up spread for its weight, producing an elegant silhouette that suits a wide range of settings. The dimensions and depth produce a balanced proportion that translates to a desirable face up size that will command presence in a ring or pendant without overwhelming more delicate designs.

Clarity and polish are critical elements in assessing a sapphire for an educated buyer, and this stone performs strongly on both counts. The clarity grade of very slightly included, recorded at eye level, indicates that any internal characteristics are minimal and do not detract from the overall transparency or light performance when viewed without magnification. For practical purposes this means the gem reads as clean to the naked eye, and the inclusions that are present are minor and localized. The excellent polish enhances the precision of the facet junctions and the smoothness of the pavilion and crown facets, which directly affects the brightness and contrast pattern you see when the stone is set. The mixed brilliant cut is specifically chosen to optimize return of light in oval proportions, combining the contrast of step or pavilion facets with the sparkle of brilliant style facets on the crown, so the result is a balance of depth and flash that educated connoisseurs appreciate.

Color is the primary driver of value in colored gemstones, and the intense yellowish green hue of this sapphire is an attractive and relatively rare offering within the sapphire palette. Yellowish green sapphires typically derive their color from iron and related trace elements distributed within the corundum crystal structure, and the specific balance of hue, tone, and saturation determines whether the stone appears more yellow or more green in different lighting. This particular stone shows an intense saturation that translates into a lively, fresh appearance on the finger, and the transparency enhances the perception of depth and brilliance. The origin of the sapphire is Tanzania, a region that has become respected for producing a wide variety of naturally colored sapphires with appealing and often unusual hues. Tanzanian deposits, including known districts that yield multi colored corundum, are valued by collectors and designers because they expand the palette beyond the well known blues, and because provenance from a recognized source adds a layer of geological story and collector appeal. In the case of an untreated sapphire, the Tanzanian origin increases desirability for buyers who prefer stones with clean natural color and documented source.

From a practical and investment standpoint this 1.17 carat Tanzanian yellowish green sapphire is an excellent choice for a buyer seeking a durable, wearable, and distinctive center gem. Sapphires are members of the corundum family and rate 9 on the Mohs hardness scale, which means they are well suited to daily wear in engagement rings and other frequently worn jewelry. The lack of any enhancement or heat treatment is a meaningful premium in the marketplace, because untreated stones with strong, natural color and good clarity are significantly rarer than their treated counterparts. For the client who values transparency in sourcing and wants a natural gem with documented origin and character, The Natural Sapphire Company stands behind this sapphire with expert assessment and can provide guidance on setting choices that maximize face up color, protect the stone, and showcase its mixed brilliant faceting. Whether you are a collector looking for a distinctive specimen, a jeweler designing a bespoke piece, or an individual choosing an engagement gem that combines personality with long term durability, this Tanzanian yellowish green sapphire represents a balanced and informed choice, offering exceptional color, attractive proportions, and the reassurance of natural, untreated origin.
