1.50 Ct. Pinkish Brown Sapphire from Ceylon (Sri Lanka)

This transparent 1.50 carat oval pinkish brown sapphire presents a disciplined balance of weight and dimensions, measuring 7.81 x 6.02 x 3.83 mm, yielding a length to width ratio of approximately 1.30 that favors classic oval proportions while preserving face up spread. The stone exhibits a medium intense color intensity, a subtle and sophisticated pinkish brown tone characteristic of Ceylon material, and a clarity grade recorded as very slightly included evaluated at eye level, confirming that inclusions are minor and have minimal impact on light transmission. Enhancement is limited to professional heat treatment that stabilizes and deepens hue without obscuring natural zoning, and the finish is described as excellent polish, which enhances mirror like facet junctions and crisp facet outlines. These baseline parameters define a gem that is both technically well executed and immediately wearable in fine jewelry, with physical proportions that translate efficiently into visual mass and perceived size.

The mixed brilliant cut executed on this oval is the defining technical attribute that controls its optical performance, and the cutter has employed a geometric faceting architecture to maximize light play. The crown displays a network of angular brilliant facets that catch incident light and produce concentrated areas of white brilliance and colored fire, while the pavilion is organized to balance light return and internal reflection so that the stone avoids both excessive windowing and dead zones. With an overall depth percentage of approximately 55.4 percent the pavilion and crown angles are coordinated to favor energetic scintillation across the table and along the elongated axis, allowing the oval outline to show linear flashes during movement. The interplay of slightly elongated main facets and smaller star and lower girdle facets creates controlled contrast and a dynamic patterning of light and dark areas, enhancing scintillation without fragmenting the color. Girdle symmetry and alignment of crown and pavilion facet planes are consistent, and the excellent polish provides sharp facet junctions and high contrast that translate directly into crisp, repeatable flashes of light when the gem is tilted or rotated under direct or diffuse illumination.

From a gemological and setting perspective this sapphire is engineered to be versatile and technically satisfying. The medium intense pinkish brown hue is effectively preserved by the mixed brilliant geometry which returns a balanced combination of white light and colored flashes, making pleochroic shifts subtle and complementary rather than disruptive. The stone will exhibit lively scintillation in prong settings where light can enter and exit freely, and it will maintain strong face up color in both open backs and closed back designs when paired with appropriate metals and mounting profiles. For designers seeking to highlight the geometric faceting, a low bezel with open gallery or a cathedral prong setting will emphasize the interplay of crown reflections and pavilion return, while a halo may increase perceived brightness without masking the intrinsic tone. The Natural Sapphire Company endorses this piece for connoisseurs who value the marriage of precise cutting geometry and natural origin, and for those who appreciate Ceylon provenance coupled with conservative heat enhancement and meticulous finishing. This sapphire is presented as a technical specimen of mixed brilliant faceting that optimizes light performance and color stability, suitable for bespoke design work and informed collections.
