1.00 Ct. Color Change Sapphire from Madagascar

This 1.00 carat transparent cushion shape color change sapphire presents a technically refined combination of proportions and optical behavior, ideal for the discerning collector. Measuring 6.48 x 5.58 x 2.82 mm, the stone exhibits a classic cushion outline with gently rounded corners and balanced table dimensions that optimize its mixed brilliant faceting scheme. The cutter employed a mixed brilliant approach, deploying a brilliant facet arrangement on the crown to enhance scintillation, combined with a modified pavilion design to maximize light return and to support the stone s notable color shift. The gem displays medium color intensity, showing a clear and attractive spectrum shift from cooler bluish violet in daylight to a warmer purplish tone under incandescent lighting, a defining characteristic of quality color change sapphires. Clarity is graded slightly included at eye level, with discrete internal characteristics that are localized and do not materially interrupt the path of light through the pavilion, preserving strong transparency. The polish is excellent, yielding crisp facet junctions and minimal surface disturbance, factors that amplify the stone s apparent brilliance and contribute to precise color transitions. Notably this sapphire has no enhancement, a detail that affirms its natural state and enhances its value profile for collectors who prioritize untreated material, and its documented origin from Madagascar situates it within a recognized and respected source region for color change material.

For a high end collection this sapphire offers both technical interest and immediate wearable appeal, its mixed brilliant cut and well controlled proportions making it highly adaptable to precision settings that emphasize the color change effect. In bespoke designs, a low profile four prong or bezel with a subtle gallery will preserve the pavilion geometry while allowing optimum light interaction, and a warm metal choice will accentuate the stone s warmer color presentation. The combination of excellent polish, balanced dimensions, and untreated origin renders this gem a rare candidate for investment grade pieces, and it sits comfortably alongside other premium specimens in a connoisseur s cabinet. The Natural Sapphire Company is pleased to present this Madagascar color change sapphire to collectors and jewelers seeking technically superior, naturally untreated stones, and we can supply further photographic documentation and gemological details upon request.
