7.04 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite transparent 7.04 carat cushion shape blue sapphire from The Natural Sapphire Company is a rare and refined example of classic Ceylon gemology, with dimensions of 11.23 by 7.99 by 7.35 millimeters, a mixed brilliant cut, and an excellent polish. The combined impression of weight, proportions, and cutting style creates ideal optical balance, allowing the stone to present both a generous surface area and sufficient pavilion depth to promote strong light return. The clarity grade is very slightly included, evaluated at eye level, which means the stone appears clean to the unaided eye while retaining internal character that confirms it is natural and untreated. The vivid color intensity is pure and saturated without veering into darkness, a trait prized by collectors and connoisseurs who value clarity of hue and purity of tone. Because this sapphire is unenhanced, with no heat treatment or other interventions reported, its market stature is elevated, as natural, untreated Ceylon sapphires of this size and quality are sought for their rarity, stability, and investment potential.

From a gemological perspective, several technical qualities underpin this sapphire s intrinsic value for an educated buyer. The mixed brilliant cut blends the scintillation of a brilliant facet arrangement with the broad, deep flashes of a step or modified pavilion, producing a lively interplay of sparkle and color. The excellent polish ensures facets sit cleanly and reflect light without diffusion, which maximizes both brilliance and sharpness of facet junctions. The very slightly included clarity grade supports transparency and light transmission, two critical elements for color revelation and brilliance, while avoiding the visual detriment of obvious inclusions. Origin reporting to Ceylon, Sri Lanka, is meaningful in the marketplace, because Ceylon sapphires are historically associated with bright, velvety cornflower to royal blue hues and a certain satiny glow that differs from the deeper, more inky tones of some other deposits. For buyers who compare provenance, treatment status, and cut quality, this stone combines desirable attributes in a way that speaks to both aesthetic appeal and long term desirability.

How this sapphire will shine under different lighting conditions is one of its most compelling attributes, and the mixed brilliant cut together with vivid color intensity ensures versatile performance. In bright natural daylight, particularly in open shade, the stone will reveal its truest blue, a vivid and slightly saturated tone with crisp, scintillating flashes from the crown facets, and broad color flashes across the table due to the cushion outline. In direct sunlight the sapphire will show lively contrast, with small pinfire reflections interspersed with larger flashes of deep blue, creating an eye catching sparkle that moves with the wearer. Under warm incandescent light or candlelight the blue will deepen subtly, taking on a richer, slightly warmer appearance that emphasizes depth and saturation, while maintaining clarity and brilliance because the polished facets efficiently return light. Under cool LED lighting the stone will appear bright and electric, with high contrast between light reflections and the saturated body color, a setting where the mixed brilliant cut excels at producing crisp scintillation. In indoor, diffused lighting the sapphire will present its color more uniformly, showing the stone s vivid intensity across the table without excessive sparkle, a quality that makes it suitable for elegant, understated jewelry designs where color is the star.

For collectors and clients considering this sapphire as a center stone for a signature piece, its size and proportions make it exceptionally versatile and compelling. At 7.04 carats and with the cushion shape, the gem commands presence on a finger as shown in the imagery, yet its pavilion depth of 7.35 millimeters and refined cutting maintain optical balance so it does not appear heavied or dull. The lack of enhancement increases both aesthetic and investment value, because untreated Ceylon sapphires of this weight and vivid color are comparatively rare in the market. The Natural Sapphire Company stands behind the stone s provenance, cutting, and treatment disclosure, and our specialists can advise on setting recommendations that maximize light performance, whether the client prefers a minimal solitaire to showcase uninterrupted color, or a halo or side stone setting that enhances perceived size and brilliance. For an educated buyer seeking a natural, well cut, vividly colored sapphire with demonstrable origin and excellent polish, this stone represents a compelling synthesis of beauty, technical quality, and lasting value.
