0.39 Ct. Bluish Green Sapphire from Australia

This listing describes one transparent bluish green sapphire weighing 0.39 carat, presented in an elegant oval shape and measuring 4.70 by 3.85 by 2.79 millimeters. The gem is cut in a mixed brilliant style, combining a faceted crown with a pavilion designed to optimize return of light, and it displays an intense overall color intensity. Clarity is graded as very very slightly included, evaluated at eye level, and the stone has an excellent polish that enhances surface luster and facet definition. The sapphire originates from Australia, and it has been heat treated, a conventional and stable enhancement common to natural corundum, applied to improve color saturation and clarity without compromising structural integrity. The Natural Sapphire Company provides this description to ensure full transparency about origin and enhancement status, and photographic images accompany this listing to illustrate the stone from table and profile perspectives.

The clarity grade of very very slightly included, as observed at eye level, indicates that inclusions are minimal and require careful inspection to discern, they do not materially affect the gem when set in jewelry, and they contribute to natural identity without compromising visual appeal. Under magnification the stone will reveal fine internal growth features that are consistent with natural formation in situ, and these features are typical for Australian sapphires of this quality. The mixed brilliant cut has been executed to balance visual brilliance and scintillation with preservation of weight, the faceting pattern creates a lively interplay of light in both direct and diffuse illumination, and the excellent polish ensures that light transit across facet junctions is clean and crisp. Together, clarity, cut, and polish produce a gem that presents with an intense bluish green body color, nuanced internal reflections, and a refined overall appearance suitable for a range of jewelry applications.

On the Mohs scale of mineral hardness, sapphire registers at nine, placing it second only to diamond at ten in common gem materials, this ranking indicates a high resistance to scratching from most household materials, and it makes sapphire substantially harder than topaz which is eight, and considerably harder than quartz which is seven. In practical terms this hardness supports daily wear in rings, bracelets, and pendants, provided normal precautions are observed, prong settings and well engineered bezels are both appropriate, and a protective setting can further reduce exposure to sharp impacts. Heat treatment in corundum is a widely accepted and stable process, it does not significantly alter the inherent hardness of the stone, and the excellent polish achieved after cutting will help resist accumulation of surface abrasions. Routine care should include gentle cleaning with warm water, a mild detergent, and a soft brush, avoidance of strong acids and prolonged exposure to high heat is advisable, and professional inspection of settings on a periodic basis will help maintain both security and appearance.

This Australian bluish green oval sapphire, offered by The Natural Sapphire Company, is well suited to designs that emphasize color depth and refined proportion, the compact dimensions allow for use as a center stone in a classic solitaire, as a complement in multi stone configurations, or as a distinctive accent in bespoke pieces. The intense color can be paired with warmer metals to soften the green component, or with cooler metals to accentuate the blue tones, and faceting ensures attractive presence in both daylight and artificial light. Documentation of origin and treatment accompanies the gem, providing provenance and clarity grading for informed selection, and the durable nature of corundum combined with the quality of cut and polish supports long term enjoyment when mounted in appropriate settings. The Natural Sapphire Company presents this sapphire with factual specifications and observational notes to assist in matching the stone to a design objective, and to support an informed evaluation of suitability for intended wear and setting.
