0.87 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This 0.87 carat Ceylon color change sapphire is a rare and technically compelling gem, presented by The Natural Sapphire Company, and offers the characteristics that discerning buyers seek, provenance, natural color change, and meticulous cutting. The stone is a cushion shape measuring 5.66 by 5.58 by 3.28 mm, faceted in a mixed brilliant style that balances scintillation with color concentration. Clarity is graded slightly included, evaluated at eye level, which for connoisseurs is often preferable because modest inclusions confirm natural origin without materially compromising brilliance. Color intensity is described as intense, and the polish is excellent, which together maximize the gem's ability to show its notable color shift between different lighting conditions. Importantly this sapphire has no enhancement, and it is certified as a color change sapphire, making it an investment quality piece where laboratory documentation aligns with visual attributes and Sri Lankan origin.

What gives this sapphire its unmistakable signature are the internal features and the way they interact with light to produce a unique visual personality. Under magnification you will observe a constellation of fine silk threads and isolated mineral crystals, arranged in a pattern characteristic of high quality Ceylon material. These inclusions create a soft, velvety texture within the stone that gently modulates reflections, enhancing the depth of the intense color rather than distracting from it. A small, well positioned crystal inclusion acts as a fingerprint for this specific gem, a minute identifier that collectors and gemologists use to positively match the stone to its certificate and provenance. The mixed brilliant cutting strategy accentuates the color change phenomenon, concentrating blue and violet tones under fluorescent lighting and permitting warmer purple nuances under incandescent light, while the slight inclusions impart a liveliness and authenticity prized by educated buyers. For settings, this sapphire benefits from a bezel or low prong style that protects the girdle and pavilion while allowing the light path to show the dramatic color shift, making it an exceptional choice for an heirloom ring or a focused collector piece. The Natural Sapphire Company is pleased to present this unheated, certified Ceylon color change sapphire, a stone whose internal signature and natural color chemistry together create an enduring and verifiable rarity.
