1.57 Ct. Bluish Green Sapphire from Madagascar

One transparent oval sapphire weighing 1.57 carats and measuring 7.62 x 5.92 x 4.15 mm presents a superb combination of precision cutting and natural character, offered by The Natural Sapphire Company. The gem has been fashioned in a mixed brilliant cut, with a faceted crown that maximizes scintillation and a pavilion engineered to return light efficiently, resulting in lively brilliance across the face of the stone. The proportions are balanced to the oval outline, producing pleasing symmetry and an even visual spread when set. The polish is excellent, with facet junctions executed with precision to reduce light leakage and enhance overall luster. There is no enhancement, the material is in its natural state, and the origin is Madagascar, a source known for producing distinctive color ranges in corundum.

Color characterization of this sapphire is bluish green with an intense color intensity that reads as saturated without appearing overly dark, making the hue versatile under diverse lighting conditions. The mixed brilliant faceting plays a key role in color performance, as the crown and pavilion interactions modulate tone and saturation, permitting flashes of blue and green to emerge with movement and changes in light angle. Clarity is graded as very slightly included at eye level, with minor internal features that do not detract from transparency or brilliance when examined unaided. These inclusions are typical of natural, untreated corundum and can serve as diagnostic markers of origin while having negligible impact on optical performance. The balance of intense color, transparent body, and subtle natural inclusions gives the stone a dynamic appearance and an attractive presence on the finger.

From a craftsmanship and design perspective, the oval outline and the given dimensions lend themselves well to a variety of settings, including four prong, six prong, and bezel designs, each influencing the perceived size and depth of color. The mixed brilliant cut provides a lively table facet deliverable, while the calibrated pavilion depth enhances internal fire without sacrificing strong color saturation. The excellent polish contributes to wearability by minimizing surface abrasion and promoting longevity of appearance. As corundum, sapphire scores a nine on the Mohs hardness scale, ensuring resilience against everyday wear, while the absence of treatment reduces long term maintenance concerns associated with some enhanced materials. The Madagascar provenance is relevant to connoisseurs who value geographic character, as material from this source often displays attractive blue green tones that differ from classic sapphire colors from other regions.

Regarding investment potential and future appreciation, untreated sapphires of intense color and eye level clarity command strong interest in the market, and provenance from credible sources enhances long term value. Supply dynamics favor appreciation for stones with natural, unheated origin, because the pool of high quality, untreated material is finite and increasingly sought after by collectors and investors who prefer natural state gems. The combination of a desirable oval shape, mixed brilliant faceting that optimizes optical performance, intense bluish green color, and excellent polish positions this sapphire as a compelling acquisition for those focused on value retention and potential upside. Regional supply from Madagascar has seen fluctuating output over time, which can influence price trajectories for distinctive color varieties. When paired with documentation from The Natural Sapphire Company and associated laboratory reports upon request, this gem benefits from clear provenance and verified characteristics, improving liquidity in the secondary market and appealing to buyers who emphasize traceability and ethical sourcing. For investors seeking tangible diversification within a precious materials allocation, this sapphire offers a technically sound and aesthetically pleasing option with credible prospects for long term appreciation, provided it is retained in well documented provenance and kept in proper care.
