7.06 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This Ceylon origin blue sapphire is a precision graded example, certified by C Dunaigre, weighing 7.06 carat, with exact dimensions of 11.36 by 9.24 by 6.95 millimeters, and exhibiting transparent clarity with an eye clean grade when evaluated at normal viewing distance. The gem displays an intense blue color intensity characteristic of fine Sri Lankan material, a hue that balances saturation and tone to achieve strong presence without heaviness. Treatment is limited to routine heat enhancement, a stable and widely accepted process that improves color uniformity and clarity while preserving the natural corundum structure. As corundum, the material benefits from inherent toughness and a Mohs hardness of nine, qualities that support everyday wear and a wide range of mounting options. The C Dunaigre report confirms origin, weight, proportions and enhancement, providing documented assurance for collectors and designers who require provenance as part of their purchase decision.

The cutting and finishing of this stone reflect deliberate craftsmanship aimed at maximizing optical performance, the cutting style is faceted with a radiant outline, a mixed facet design that marries brilliant crown faceting with a more geometric pavilion arrangement to achieve both fire and focused scintillation. The radiant cut in this instance features crisply executed facet junctions, an appropriately sized table plane and well balanced crown and pavilion relationships, resulting in lively light return across the table and controlled dark and light patterning across the surface. Excellent polish indicates that facet surfaces are free from noticeable abrasion or polish lines, promoting crisp contrast and mirror like facet reflections, while precise symmetry ensures that light is distributed evenly as the gem is moved. The stone exhibits strong internal light performance, with faceting choices that enhance dispersion and tonal depth, and the eye clean clarity grade means that inclusions are either absent at loupe and naked eye viewing, or positioned and oriented to minimize impact on brilliance and face up appearance.

From a design and practical standpoint this 7.06 carat radiant sapphire offers remarkable versatility, equally suited to elevated daywear and formal evening pieces, its intense blue face up color reads clearly under a variety of lighting conditions and pairs well with multiple metal palettes. For a contemporary look, mounting in platinum or 18 karat white gold will emphasize the cool blue saturation and accentuate scintillation, while 18 karat yellow or rose gold will introduce a warmer contrast that can make the blue appear more vivid and three dimensional. The radiant outline with trimmed corners is compatible with prong settings that expose the crown to light, as well as bezel or half bezel settings that provide additional protection without sacrificing visual impact. The depth and proportions of this stone also allow for creative design as a center stone in a solitare ring, as the focal element in a pendant, or as a pair of matched stones for a bespoke two stone composition. For clients seeking a modern profile, lower bezel rails with substantial gallery work will protect the girdle while retaining brilliance, and for those who prefer classic silhouettes, a four prong cradle with a raised setting will present the color and faceting to optimum effect.
