7.22 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This gem is a transparent oval blue sapphire weighing 7.22 carats, and it measures 13.69 x 9.04 x 6.73 mm, and its proportions reflect a cutter focused on balancing color saturation with optical performance. The mixed brilliant cut combines a brilliant style crown with complementary pavilion faceting, and this arrangement is engineered to retain weight while promoting broad flashes of light and strong color return. Clarity is graded as eye clean at eye level, and this allows uninterrupted color flow across the table, while the excellent polish sharpens facet junctions and maximizes specular reflection. The sapphire displays a dark color intensity, and the hue reads as a deep Ceylon blue characteristic of Sri Lankan material, and the stone has been heat treated to enhance tone and saturation in a stable, industry standard manner. The dimensions and oval outline provide a generous face up area, and the mixed brilliant geometry yields a balance between scintillation and large zone color, which is particularly desirable in larger stones where even, saturated color is a premium attribute.

From an optical and lapidary perspective this sapphire exhibits the hallmarks of considered craftsmanship, and the mixed brilliant cut produces a layered light performance. The brilliant facets on the crown create lively return and flashes, and the pavilion planning complements this with broader color windows and controlled light leakage. The excellent polish reduces surface diffusion, enabling crisp contrast between bright facet reflections and the darker body color, and this contrast is essential for a dark intensity sapphire to read with vitality rather than as a flat mass. The eye clean clarity grade means interior features are not apparent to the naked eye, which contributes to a clean field and uninterrupted color saturation. Origin from Ceylon lends a particular blue character that is often described as velvety and well balanced between blue and slight secondary tones, and the standard heat treatment applied here is disclosed and stable, it optimizes the stone without compromising structural integrity. Taken as a whole, the combination of cut, clarity, and polish delivers a gem that interacts with light in a way that emphasizes depth, and that reveals subtle internal luster when viewed in both natural and artificial light.

In practical settings this sapphire will stand out in any jewelry configuration, and its dark intensity makes it a commanding centerpiece for solitaire rings, and equally effective as the focal point in three stone designs or halo compositions. In white metal settings the cool reflective backdrop accentuates the deep blue, and in yellow gold the warm metal creates a classic contrast that can make the blue appear richer and more saturated. The oval outline provides visual elongation on the finger, and the mixed brilliant facets create flashes that break up the dark body color, which produces movement and interest with every gesture. For pendant work an open back setting will allow more light to enter the pavilion and reveal internal depth, and for closed back or more dramatic, theater style settings the dark intensity will read as a deep, velvety blue that commands presence.
