1.19 Ct. Bluish Green Sapphire from Australia

This transparent 1.19 carat fancy shape bluish green sapphire measures 5.93 by 6.11 by 3.69 mm, and has been expertly fashioned in a precise step cut that emphasizes planar facet geometry, crisp facet junctions, and a broad table. The step cut yields a controlled hall of mirrors effect, allowing the intense color intensity to present as richly saturated bluish green flashes across the crown and pavilion, while the excellent polish maximizes return and minimizes surface scattering. Clarity is graded very slightly included, evaluated at eye level, which in combination with the gemological characteristics of Australian corundum gives the stone both visual depth and practical eye clean appearance. Enhancement by heat treatment was applied to optimize tone and saturation, and the cutting proportions preserve weight while maintaining ideal facet angles to enhance pleochroic behavior, showing subtle shifts between greener and bluer tones as the stone is rotated.

What truly distinguishes this sapphire is its set of unique inclusions that act as an unmistakable signature, and a fingerprint of its origin and treatment history. Under magnification one observes oriented arrays of fine needle like silk and minute mineral platelets aligned with the natural growth directions, producing a delicate internal texture that softens the intense color and contributes to a velvety depth. There are also isolated angular crystal inclusions and narrow healed fractures with partially annealed walls that record the thermal history, features consistent with controlled heat treatment that reduced silk density without eliminating the distinctive internal architecture. Subtle growth zoning and lamellar twinning planes are visible through the step pavilion, and these planar features refract light into layered color bands that are particularly pronounced in step cut facets, reinforcing the bluish green signature. These inclusion characteristics are diagnostic on a technical level, they confirm natural origin from Australia, and they provide character that no synthetic or heavily treated material can convincingly reproduce. At The Natural Sapphire Company we present this stone for connoisseurs who value precise faceting, documented enhancement, and the unmistakable internal fingerprint that makes this Australian sapphire a technically interesting and visually compelling selection.
