11.04 Ct. Greenish Blue Sapphire from Madagascar

This rare greenish blue cushion sapphire carries immediate presence and confidence, it is C.Dunaigre certified which verifies its identity and important gem characteristics, it weighs 11.04 carats and measures 12.70 x 12.39 x 7.46 mm which places it well above the size most collectors encounter when seeking this particular hue. The color is described as greenish blue with intense saturation, it is transparent and displays a deep velvety tone that shifts subtly with movement, the mixed brilliant cut has been executed to balance strong face up color with lively scintillation, and the clarity is graded as very very slightly included evaluated at eye level which means the gem appears eye clean to most observers while retaining excellent natural character. Enhancement is heat treated which is a stable and widely accepted method that improves color and clarity in sapphires without undermining long term durability, the origin is Madagascar which is known for producing a wide spectrum of blue and teal sapphires with vibrant and unusual colors, and the polish is excellent which enhances light return and allows the intense color to read cleanly under most lighting conditions.

When compared to other sapphires available on the market this stone stands apart in both scale and tone, many greenish blue sapphires are found in sizes under five carats which limits the impact a setter can achieve, stones that do reach double digit carat weights commonly lean more toward forest green or deep blue without the luminous greenish blue balance that defines this gem. Compared to commercially available teal sapphires from other sources this Madagascar example boasts a more saturated and consistent color distribution which translates to stronger visual appeal in finished jewelry, compared to Sri Lankan sapphires which often exhibit lighter cornflower blue tones this gem offers a more dramatic and modern palette while maintaining the clarity and brilliance that discriminating buyers expect. The mixed brilliant cut differentiates it from many large step cut or antique style cushion cuts which can appear glassy or prone to dark windowing in deeper colors, here the pavilion and crown faceting have been balanced to produce a lively and even appearance across the table and crown facets, in short this sapphire offers a rare convergence of size, color intensity, cutting precision and eye clean clarity that is difficult to find in comparable stones.

As a design element this 11.04 carat cushion greenish blue sapphire is remarkably versatile while remaining a statement gem, the generous face up area created by its 12.70 x 12.39 mm dimensions delivers a commanding presence in an engagement ring, cocktail ring, or a bespoke pendant, the cushion silhouette flatters both classic and contemporary settings and adapts easily to halo, bezel, or solitaire presentations. The intense greenish blue hue will read differently against warm metals and cool metals, set in yellow or rose gold the gem can lean greener and warmer, set in platinum or white gold it will emphasize the bluer side of its palette and appear cooler and more jewel like, the excellent polish and mixed brilliant cut ensure that light return is maximized so the stone appears lively and alive on the finger rather than dark and static. Functionally sapphires rank high for everyday wear which makes this gem a practical choice for an heirloom ring, its hardness provides strong resistance to scratching and edge wear, and the heat treatment commonly used for color enhancement is stable under normal jewelry care, for customers who value a natural yet refined aesthetic the very very slightly included clarity grade means the stone will present as clean to the eye while retaining natural origin characteristics that many connoisseurs prize over completely flawless but synthetic alternatives.
