1.08 Ct. Yellowish Green Sapphire from Australia

This transparent 1.08 carat asscher octagonal yellowish green sapphire measures 5.98 x 5.40 x 3.43 mm, a set of proportions that immediately communicates intentional planning by a skilled cutter, and a weight that meaningfully elevates both market value and collector interest. Carat weight in corundum is not simply a numerical designation, it is a direct factor in rarity, particularly for colored varieties that exhibit unusual hues. At 1.08 carat this sapphire crosses a perceptual threshold, where the gemstone reads as a full carat in appearance and presence, while retaining compact dimensions that optimize wearability and design flexibility. The dimensions provided align closely with expected volume for a corundum of this specific gravity, and the depth at 3.43 mm indicates a mindful balance between color saturation and light return. Heavier stones in this size category are less common for yellowish green tones, especially in natural, unenhanced material, which is why the weight itself confers a premium, beyond the already desirable intense color intensity and excellent polish.

The asscher cut, executed on an octagonal outline, employs a step facet architecture that differs materially from brilliant cuts, and the faceting strategy here deliberately emphasizes color distribution and optical depth. The asscher geometry creates concentric, square stepping planes on the crown and pavilion that channel light in broad, reflective galleries, producing a distinct type of luster and a controlled scintillation pattern. In a colored sapphire where saturation and tone are paramount, a step cut like this reduces unwanted scintillation glare and instead concentrates color into planes that the eye reads as uniform and deep. The cutter has maintained pavilion angles and crown heights that avoid excessive windowing, while preserving table proportions that balance surface reflection with internal light traversal. Excellent polish on all facets is critical for this result, because any minute surface irregularity on a step facet will interrupt the crispness of flashed planes, and the polish here ensures crisp facet junctions and smooth optical transmission, enhancing perceived clarity and color intensity.

Color and clarity are the twin variables that determine both aesthetic appeal and value, and this sapphire presents an intense yellowish green hue with transparent material quality. Intense color intensity indicates high saturation without tipping into oversaturation that might impair tone, and the yellowish green axis is an uncommon and desirable area of the corundum color spectrum. The declared clarity grade, slightly included when evaluated at eye level, describes inclusions that are detectable with unaided vision under direct observation, yet do not fundamentally interrupt the gem s window of color or its structural integrity. Inclusions present in step cut stones often align with facet planes and may be less distracting than in brilliant cuts, especially when the cutter positions them near facet junctions or within areas that reflect light, thereby masking their visual impact. Importantly, this sapphire is unenhanced, with no heat treatment or diffusion recorded, which in the marketplace confers a significant premium, particularly for material originating from Australia where consumers and trade buyers place value on natural state specimens. The combination of natural intense color, transparent body, and no enhancement provides reassurance about color origin and stability, and supports higher long term value.

From a valuation and design perspective the 1.08 carat weight is a defining characteristic that elevates this example above smaller, more common sizes. In colored gem trading the jump from under one carat to just over one carat often triggers stronger buyer perception, increased retail price bands, and greater interest from bespoke jewelers seeking statement yet wearable stones. The physical size allows the asscher faceting to express its pattern clearly to the naked eye, making the step planes and internal color galleries readable without magnification, which is essential for collectors and designers who prioritize the interplay between cut and hue. For mounting recommendations, protective settings that shield the corners of the octagonal asscher are advisable, such as bezel variants or prong designs that cradle the girdle without obscuring the pavilion s light window. The Natural Sapphire Company presents this gemstone as part of a curated approach to natural, unenhanced material, and provenance from Australia further supports its narrative of rarity. Collectors and connoisseurs will appreciate that the weight, combined with asscher faceting, intense yellowish green color, transparent body, slight eye level inclusions, excellent polish, and absence of enhancement, together create a gemstone that is both technically interesting and financially resilient.
