0.94 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent Ceylon Sri Lanka blue sapphire weighs 0.94 carat, and measures 6.94 by 4.95 by 3.30 millimeters, yielding a length to width ratio of approximately 1.40 to 1, and a depth of approximately 55.6 percent, proportions that deliver an elegant oval outline with balanced spread and face up presence. The gem is fashioned in a mixed brilliant cut, combining a full brilliant crown with a modified pavilion facet structure to optimize scintillation and light return, and the facet alignment exhibits even symmetry and crisp facet junctions. Color is medium intensity blue with a subtle cool undertone that is characteristic of high quality Ceylon material, and the stone is heat treated to enhance tone and saturation, a stable and industry standard enhancement. Clarity is graded very very slightly included, evaluated at eye level, which communicates exceptional clarity to the naked eye while preserving natural character under magnification. The polish is excellent, producing crisp facet reflections and lively contrast between flashes and broad areas of color, and the overall optical performance favors dynamic scintillation in both diffuse and direct light.

For an engagement ring application this sapphire is technically ideal, offering a near one carat weight that balances wearability and visual impact, and its mixed brilliant geometry is particularly well suited to settings that prioritize light entry and scintillation. A four or six prong cathedral style will allow maximum pavilion light return while securing the oval outline, and a low bezel or tension setting can be specified for enhanced protection when daily wear is anticipated. If increased visual weight is desired, a well proportioned halo of small brilliant cut diamonds will enlarge the apparent table and create a lively perimeter of sparkle without compromising the sapphire tone. Durability is inherent to corundum, making this stone suitable for everyday engagement wear, and the heat treatment applied is stable under normal conditions. At The Natural Sapphire Company we can recommend exact mounting proportions to preserve the stone proportions, and provide bespoke setting options to optimize table exposure, prong placement, and overall finger ergonomics. This Ceylon sapphire combines precise cutting, strong polish, excellent clarity, and a textbook oval profile, making it a technically refined and romantically appropriate choice for an engagement ring.
