1.23 Ct. Greenish Blue Sapphire from Australia

This is a transparent 1.23 carat cushion shape greenish blue sapphire, measuring 5.83 by 5.27 by 4.45 millimeters, presented by The Natural Sapphire Company. The stone is cut in a mixed brilliant style, combining the scintillation of brilliant facets with the depth and color control of step facets. Clarity is graded as very very slightly included at eye level, meaning the inclusions are extremely minor and do not detract from face up appearance or durability. Color intensity is vivid, and the surface displays an excellent polish, which together produce a lively and saturated greenish blue tone. The sapphire is heat treated, a conventional and stable enhancement that improves clarity and color without affecting long term stability. Origin is Australia, a source known for distinctive, slightly cooler blue greens and for producing gems with reliable tone and good crystallographic quality.

The mixed brilliant cut is integral to how this sapphire interacts with light. The cushion silhouette provides broad, softly curved facets on the crown that act as windows into the gem, while the brilliant style facet pattern maximizes internal reflection and scintillation. The inclusion of step influenced facets on the pavilion preserves and intensifies the core color, allowing light to be absorbed and reflected in a way that deepens the greenish blue hue without sacrificing brightness. The interplay of small brilliant facets and larger pavilion facets creates a balance between flash and body color, so that movement produces flashes of white light as well as flashes of colored light, enhancing both sparkle and saturation. Excellent polish ensures that facet junctions are crisp and that light crosses facets with minimal loss, increasing return of light to the viewer.

For an educated buyer, this sapphire offers a compelling combination of attributes, clarity, color, and cut, all backed by the provenance of Australia and the reliability of The Natural Sapphire Company. At 1.23 carats the gem is substantial enough for a confident center stone in classic and modern settings, while the vivid greenish blue color and very very slight inclusions support both aesthetic and investment considerations. Heat treatment is disclosed and consistent with industry practice, and the excellent polish and mixed brilliant cutting technique make this stone a durable, brilliant, and color rich example of fine sapphire material.
