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

This 7.99 carat transparent emerald cut sapphire presents a striking greenish blue hue, and it measures 11.27 x 9.22 x 8.07 millimeters, making it substantial enough to command attention in any jewelry design. The stone is faceted to an emerald cut geometry, with a broad, flat table and linear step facets across the crown and pavilion that create the signature hall of mirrors effect unique to step cuts. Evaluated at eye level, the clarity grade is very very slightly included, which translates to exceptional transparency and a clean face up appearance, allowing the intense color to read consistently across the table. Origin certified as Ceylon Sri Lanka, this sapphire carries the geographic signature of lively saturation and a refined balance between blue and green tones, and the piece is offered through The Natural Sapphire Company with full transparency about enhancement, namely heat treatment applied to improve color and clarity in a stable and permanent manner.

From a lapidary perspective the emerald cut faceting on this sapphire emphasizes color and clarity over scintillation, and the precision of the step facets along the crown and pavilion produces linear flashes of light rather than the dispersed brilliance typical of brilliant cuts. The broad table acts as a large color window, revealing uniform saturation and allowing the intensity of the greenish blue to be appreciated at a glance. Facet junctions are executed with exacting symmetry, and the polish has been graded excellent, which means facet surfaces are mirror smooth and reflections are crisp, maximizing light return and internal contrast. The gem proportions yield a depth that reads as approximately seventy nine percent of the average girdle diameter, which contributes to a rich face up color saturation, and this depth is a deliberate trade off used by master cutters to enhance color in stones of this tonal range.

The very very slightly included clarity at eye level indicates that inclusions are minute and do not interfere with the optical performance of the stone, and under magnification typical features are confined to fine needles and pinpoint crystals that are well positioned within the step facet pattern. Because the emerald cut presents a wide, open table, inclusion visibility is a critical consideration, and the high clarity of this example makes it ideal for open settings where the stone is viewed directly. Heat treatment is disclosed, and this accepted treatment for corundum has been applied to stabilize and intensify the stone color without compromising structural integrity. Ceylon origin contributes materially to the character of the color, with trace elements producing a lively, transparent greenish blue that exhibits subtle pleochroic shifts depending on viewing angle, a desirable optical attribute that adds depth and life to the gem. The underlying material is corundum with a hardness of nine on the Mohs scale, providing resilience for everyday wear when properly set and cared for.

For a statement piece this sapphire is exceptionally well suited, and its size and high eye level clarity make it a prime candidate for settings that showcase the stone as the central focus. In a solitaire ring the long rectangular profile will create an elegant finger presence, while a halo of matched melee diamonds can increase apparent size and intensify perceived color through contrast. For protective considerations the stepped corners can be secured with partial or full bezels, or with four to six prong settings that are tailored to protect the geometry while allowing the table to read fully. The stone also translates beautifully to pendants and brooches, where the broad table and intense color will read beautifully from a distance, and the emerald cut lends itself to architectural designs that emphasize clean lines and refined proportions. At The Natural Sapphire Company we can advise on mounting options, provide custom design services, and arrange gemological documentation to accompany the purchase, ensuring that the size, clarity, and craftsmanship of this 7.99 carat Ceylon emerald cut sapphire are matched by professional settings that elevate it into a true statement jewel.
