0.58 Ct. Padparadscha Sapphire from Tanzania

This cushion shaped padparadscha sapphire weighs 0.58 carat, a weight that places it in a rare and highly desirable category for untreated stones of this color family. Its calibrated dimensions are 5.45 by 4.26 by 2.60 millimeters, yielding a depth ratio of 53.6 percent when measured against the average of length and width, a proportion that is optimized for balanced light return and color saturation. At 0.58 carat the stone benefits from a face up presence that is greater than its millimeter dimensions might suggest, because corundum has a specific gravity in the range of 3.99 to 4.03 which concentrates weight into a compact outline. This concentrated weight combined with the cushion shape produces a comfortable visual mass when set, and moves the stone into price brackets that reflect the scarcity of well colored, untreated padparadscha material at and above the half carat mark. For collectors and designers who evaluate value through both optical performance and rarity, the 0.58 carat point is a meaningful inflection where supply tightens and premium for natural color increases nonlinearly.

The cutting and surface finish of this gem emphasize both optical control and preservation of natural hue, it is fashioned with a mixed brilliant faceting scheme that integrates a modified brilliant crown with a slightly stepped pavilion, the configuration is selected to enhance scintillation while maintaining even color distribution. Mixed brilliant faceting is particularly appropriate for padparadscha sapphires, because the brilliant facets on the crown disperse light and create lively scintillation, while the pavilion treatment controls light leakage and deepens the apparent saturation of the pink orange hue. The polish is graded excellent, indicating crisp facet junctions and minimal polish lines, which in turn maximizes specular reflection and luster. Clarity is evaluated as slightly included at eye level, a grade that denotes small but visible internal features which do not substantially interrupt the gem s overall transparency or light path. These modest internal characteristics often serve as internal fingerprints that confirm natural origin and reassure the trained buyer that the color has not been artificially intensified.

Color is assessed as medium intensity, a tonal and saturation grade that is often favored for padparadscha because it preserves the delicate salmon balance between pink and orange while avoiding brownish or oversaturated tones that can diminish desirability. This stone displays the trademark balance of pink and orange hues that results from the particular trace element chemistry of Tanzanian sources, a balance that is rare in untreated material. The absence of enhancement is a critical factor in the market valuation of padparadscha sapphires, because untreated examples retain both the natural distribution of color and the stability of chromophore concentration. For connoisseurs, a 0.58 carat, untreated padparadscha with a medium intensity color grade, a mixed brilliant cut, and excellent polish represents an intersection of geological rarity and lapidary skill.

From a practical and investment viewpoint the weight of 0.58 carat is especially important, because gemstone pricing is commonly tiered and weight increments around one half carat often trigger pronounced increases in per carat value for rare varieties. The combination of this weight with a cushion outline and a 5.45 by 4.26 millimeter face up footprint makes the gem highly versatile for use as a center stone in fine rings, as an accent in three stone settings, or as a refined focal point in a pendant where the color can be viewed against both light and skin tone. The Natural Sapphire Company provides full specification documentation that records the weight, dimensions, cut style, clarity grade, color intensity, enhancement status, and origin, ensuring traceability and confidence for buyers. For specialists seeking a technical combination of desirable carat weight, measured optical performance, and verified untreated Tanzanian origin, this 0.58 carat cushion padparadscha sapphire is an exceptional candidate.
