1.10 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This heart shaped blue sapphire offered by The Natural Sapphire Company is a finely proportioned 1.10 carat gemstone, measuring 5.81 x 6.24 x 4.03 mm, with a transparency and surface finish that immediately signal professional lapidary work. The stone is cut in a mixed brilliant style that combines a faceted crown optimized for light penetration with a pavilion geometry engineered for maximum return of light, creating a balance between flash and depth. Color is classified as intense, exhibiting a saturated blue that leans toward the classic Ceylon tonal range, and clarity is graded as very slightly included, evaluated at eye level, which means the minor internal features do not interfere with the overall visual performance when set or viewed face up. The polish is excellent, allowing sharp facet junctions and mirror like facet planes to enhance scintillation and contrast. Origin is Ceylon, Sri Lanka, and the sapphire has no enhancement, a combination that underscores the natural character of its color and crystal habit.

From a gemological and cut engineering perspective, this heart shaped sapphire demonstrates thoughtful facet planning and execution, beginning with a well defined heart cleft and symmetrical lobes that require precise pavilion alignment to preserve pavilion brilliance. The mixed brilliant approach here uses a brilliant facet arrangement on the crown to generate dispersed white light and scintillation, paired with step influenced pavilion shaping that deepens color and improves light return at oblique angles. The measured depth of 4.03 mm yields a depth percentage of approximately 67 percent when referenced to the average of length and width, a depth consistent with balanced face up spread and internal light performance for a mixed cut of this shape. The girdle appears consistent and even, contributing to secure mounting options, and the culet is proportioned to avoid light leakage while supporting the heart silhouette. Under loupe inspection at normal viewing distances, the inclusions are minor, situated in positions that do not create windowing or dead zones, and the facet symmetry preserves an even pattern of light and dark areas that enhance perceived saturation and brilliance.

As a centerpiece in any collection, this sapphire offers both technical refinement and collector appeal, its combination of intense natural color, no enhancement provenance, and exacting cut work making it well suited for bespoke settings that emphasize the heart motif. For design applications, the stone performs particularly well in open head settings that allow light to enter from the pavilion, or in low profile bezels that protect the girdle without constraining the crown, and its well balanced proportions adapt to halo or solitaire configurations depending on desired emphasis for color versus brilliance. From an investment perspective, unenhanced Ceylon sapphires with controlled clarity and an intense color saturation represent a desirable segment of the market, and the execution of the mixed brilliant heart cut here amplifies the visual impact when compared to standard cuts of equivalent weight. If you require additional magnified images, angle specific light studies, or mounting recommendations, The Natural Sapphire Company can provide detailed support and bespoke services to ensure the final setting preserves both optical performance and structural security, making this heart shaped sapphire a lasting focal point in any fine jewelry collection.
