0.92 Ct. Yellowish Green Sapphire from Madagascar

I am pleased to present a transparent 0.92 carat round yellowish green sapphire, a gem that combines measured proportions with considered lapidary technique to accentuate its intrinsic color and brilliance. The table to girdle dimensions measure 5.74 x 5.74 x 3.93 millimeters, corresponding to a depth ratio of approximately 68.5 percent relative to diameter, a slightly deep profile that concentrates color face up and yields a rich medium color intensity. The stone is cut as a mixed brilliant, employing a brilliant faceted crown paired with a modified pavilion to balance scintillation with color saturation. Faceting precision is evident in uniform symmetry and an excellent polish that produces crisp facet junctions and lively return of white light. Clarity is graded as very slightly included, evaluated at eye level, with small internal features typical of natural corundum that do not impede transparency or visual performance. This sapphire has undergone controlled heat treatment as an enhancement, a conventional and stable process employed to improve color homogeneity and to reduce the prominence of some internal features, and the origin is Madagascar as determined by our gemological assessment at The Natural Sapphire Company.

The journey of this sapphire begins in Madagascar, where gem bearing veins and alluvial deposits yield corundum material of varied color and character. Field teams work in small scale operations utilizing careful extraction to preserve crystal integrity. Rough pieces are inspected on site, with the most promising crystals selected for transport to our cutting partner under documented chain of custody. In the preforming stage the cutter assesses rough orientation, mapping color zoning and internal features using magnification and transmitted light. The decision to execute a mixed brilliant round was driven by a desire to marry face up brightness with enhanced color concentration. During bruting and faceting, pavilion angles were adjusted to accommodate the naturally occurring color saturation, avoiding excessive shallowness that would dilute hue, and avoiding extreme steepness that would trap light. The stone was heat treated in a controlled environment to stabilize its yellowish green hue, following analytical verification including refractive index measurement and spectroscopic examination to confirm natural origin and to detect treatment history. Throughout cutting and treatment processes quality control checks verified symmetry, facet alignment, polish quality, and consistency of color across the table and crown.

At final inspection the sapphire presents as a versatile center stone for precision jewelry work, offering a balanced combination of color, clarity, and optical performance. The medium color intensity and yellowish green hue respond particularly well to open settings that allow light to penetrate the pavilion, and to halo combinations that amplify perceived size while maintaining the gem's natural character. The very slightly included clarity grade assures that the stone reads clean to the eye, while internal features provide natural fingerprinting that certifies authenticity when compared to documentation. The excellent polish contributes to crisp highlights and strong brilliance, a benefit for settings that emphasize facet play. As representatives of The Natural Sapphire Company I can confirm that full disclosure accompanies this piece, including the heat treatment history, Madagascar origin, and measured dimensions. We recommend standard corundum care, avoiding sudden thermal shock and abrasive chemicals, and suggest routine inspection of settings to maintain security. For buyers who appreciate technical detail and artisanal provenance this sapphire represents a considered example of thoughtful cutting, stable enhancement, and documented sourcing, and I welcome inquiries for additional imagery, spectroscopy data, or to discuss bespoke mounting options that will showcase this gem to maximum effect.
