1.65 Ct. Blue Sapphire from Australia

This stone is a transparent 1.65 carat oval shape blue sapphire, measuring 8.10 x 6.42 x 3.80 mm, cut in a mixed brilliant style and originating from Australia. The clarity is graded as very very slightly included evaluated at eye level, describing an eye clean appearance with only minimal internal features visible under magnification. Color intensity is classified as dark, producing a richly saturated blue in face up views. The pavilion and crown facets exhibit an excellent polish, and the gem has undergone standard heat treatment to enhance color and stability. The Natural Sapphire Company provides this technical profile to support informed selection and setting decisions.

The gem’s eye clean clarity and precise cutting together enhance its beauty from every angle. Minimal inclusions allow unimpeded light transmission through the table and crown, so the face up appearance is uniformly deep blue without localized clouding or dark spots. The mixed brilliant cut balances large and small facets to optimize return of light and scintillation, so movement reveals crisp flashes and even color distribution rather than inconsistent dark areas. Excellent polish at facet junctions produces sharp reflections and clean facet outlines, which accentuate the gem’s visual definition when viewed at oblique angles and in profile. The proportions implied by the 8.10 x 6.42 x 3.80 mm measurements yield a pleasing depth to table ratio that supports both strong color saturation and adequate light return, maintaining presence in ring or pendant settings. Heat treatment has been applied to stabilize and enhance the natural blue tone, while origin from Australian deposits contributes a characteristic deep, slightly inky hue that is both formal and versatile. Taken together, the high clarity, considered proportions, mixed brilliant faceting, and excellent finish result in a sapphire that presents as consistent and refined from the table, crown, and pavilion perspectives, making it suitable for designs that emphasize clean lines and enduring color. The Natural Sapphire Company offers this gem with documentation of its characteristics to assist lapidaries and jewelers in achieving the intended visual outcome.
