1.21 Ct. Bluish Green Sapphire from Australia

This transparent 1.21 carat asscher octagon shaped bluish green sapphire represents a precise balance of size, color, and cutting quality, making it an excellent choice for custom jewelry projects. The gem measures 6.01 x 5.18 x 3.93 mm and displays an asscher cut that emphasizes geometric symmetry and controlled light return. The clarity has been graded as very slightly included when evaluated at eye level, and the polish has been assessed as excellent. The color intensity is described as intense, producing a vivid bluish green tone that remains elegant at this scale. The sapphire has been heat treated, a standard and stable enhancement in the trade, and its documented origin is Australia. These attributes together define a stone that is both technically sound and visually appealing for bespoke settings.

The measurements and the asscher octagon shape make this sapphire particularly versatile for custom design. At 6.01 x 5.18 mm, the stone is large enough to function as a fine center stone in rings and pendants, while its octagonal asscher geometry also lends itself well to side stone placement in multi stone arrangements and to matched pair designs for earrings. The modest depth of 3.93 mm supports a low profile mounting when desired, and the overall proportions favor settings that showcase the step cut planes and square like symmetry novel to the asscher style. Designers and jewelers will find this stone compatible with a range of mounting styles including solitaire, halo, three stone, and modern bezel configurations, each option leveraging the asscher cut to highlight linear facet relationships and internal clarity.

Color and color stability are central considerations when integrating a sapphire into a custom piece, and this gem offers an intense bluish green that adapts well to different metals and accent stones. Set in warm yellow gold, the tone will read richer and more classical, while white metals such as platinum or white gold will emphasize a cooler, more contemporary presentation. The intensity level ensures the color remains present under mixed lighting, and the bluish green hue pairs harmoniously with white diamonds and colorless gemstones, allowing for elegant contrast and compositional restraint when designing a piece. The heat treatment applied is industry standard and improves both color saturation and overall clarity without compromising durability, making the stone suitable for everyday wearable jewelry.

The asscher cut itself merits attention for custom work due to its step cut faceting and emphasis on clarity and symmetry. Step cuts produce a hall of mirrors effect that rewards clean material and precise facet alignment, and the very slightly included clarity grade at eye level indicates the stone will present with minimal distraction under normal viewing conditions. The excellent polish contributes to crisp facet junctions and strong reflectivity along the facet planes, which is especially important with an asscher cut where facet edges define the visual character. For clients seeking a gemstone that reads as refined and architectural, this sapphire offers the legibility needed for designs that rely on linear form and balanced proportions, rather than the scintillation oriented approaches typical of brilliant cuts.

The Natural Sapphire Company provides this Australian origin asscher sapphire as a distinct option for bespoke commissions or refined ready to set creations. Given the stone size and shape, it is particularly appropriate for clients and designers aiming to create a signature ring or pendant with a strong center presence, and for pairings where matched proportions and coherent facet language are important. We recommend consulting our gem specialists early in the design process to review mounting options that protect the pavilion and secure the stone while allowing its asscher geometry and intense bluish green color to remain the focal point. Specifications and provenance documentation can be provided upon request, and our workshop can advise on practical considerations such as prong placement, bezel tolerance, and profile adjustments to achieve an optimal finished piece.
