3.56 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

One transparent 3.56 carat round shape greenish blue sapphire is presented with precise dimensions of 8.71 by 8.57 by 5.92 mm. The gem has been fashioned with a mixed brilliant cut, combining a faceted crown and a well proportioned pavilion to maximize light return, and it displays an intense color intensity with a clear greenish blue hue. Clarity has been assessed as very slightly included, evaluated at eye level, and the stone benefits from an excellent polish that produces crisp facet junctions and lively surface reflections. The sapphire has been heat treated, a standard and stable enhancement, and its origin is Ceylon, Sri Lanka. The Natural Sapphire Company provides this information with full disclosure, reflecting our commitment to accurate gem reporting and responsible sourcing.

The greenish blue color of this sapphire is the defining aesthetic characteristic, and its intensity is notable for its depth and evenness across the table and through the girdle. Depending on the viewing angle and light source, the stone exhibits subtle variations between the blue and green components, producing a nuanced and dynamic appearance. The mixed brilliant cut accentuates these color shifts, as the crown facets disperse light into a spectrum of small flashes, while the pavilion facets return concentrated tones to the eye, creating both scintillation and saturation. This optical performance is characteristic of high quality Sri Lankan sapphires, which are prized for their lively, oceanic hues that remain engaging in both daylight and artificial illumination. The overall transparency allows for clear passage of light, enhancing perceived depth and lending the gem a glass like purity that complements its rich color.

Clarity and cutting quality together determine how a sapphire reads at a glance, and this gem’s very slightly included clarity grade indicates minor natural features that do not interfere with visual enjoyment at normal viewing distances. The excellent polish amplifies facet brightness and ensures that light is reflected cleanly rather than scattered by surface irregularities. The carefully controlled proportions implied by the listed dimensions produce a pleasing face up size and balanced profile, allowing the sapphire to sit confidently in a variety of settings while retaining strong face up presence. The mixed brilliant design also provides a modern yet classic silhouette, offering both the sparkle associated with brilliant cutting and the depth of a traditional pavilion arrangement. For a wearer who values both optical performance and refined proportions, this stone presents a thoughtful combination of attributes.

Over the years the inherent qualities of this sapphire will continue to captivate for several practical and aesthetic reasons. Corundum ranks high on the Mohs hardness scale, providing resilience to everyday wear and helping preserve polished facets and crisp facet junctions with normal use. The applied heat treatment is a permanent enhancement that stabilizes color, meaning the intense greenish blue tone will remain consistent under ordinary conditions, and routine care involves simple cleaning methods that avoid harsh chemicals and extreme temperature changes. The stone’s enduring appeal also derives from the subtleties in its color that reveal themselves with changing light and perspective, creating an element of discovery that does not fade with time. As an heirloom quality gem, it combines visual interest, technical soundness, and documented origin and treatment, making it a durable and reliable candidate for long term enjoyment.
