0.44 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.44 carat round blue sapphire measures 4.38 x 4.54 x 2.77 mm, and is cut in a faceted mixed brilliant style, combining a brilliant crown with pavilion facet geometry engineered to maximize scintillation while preserving color saturation. The mixed brilliant cut provides a strong return of light through the table, producing lively flashes across the facets, while the pavilion scaling retains the deep blue hue characteristic of Ceylon origin. Clarity is graded slightly included at eye level, and the stone displays excellent polish, which enhances facet delineation and surface reflection. Heat treated enhancement has been applied in a controlled manner to intensify the vivid color intensity, a common and stable treatment for Sri Lankan sapphires. Girdle proportions and small dimensions make this gem especially suitable for detailed, precision settings where proportion and symmetry are critical to optical performance, and The Natural Sapphire Company certifies the origin as Ceylon, a provenance valued for its consistently saturated, vivid blue tones.

This sapphire is highly adaptable to a wide range of custom jewelry settings, and its technical attributes inform optimal mounting choices. For maximum visibility and brilliance, a four or six prong solitaire with tapered, fine prongs will expose the table and preserve light performance, ideal for a delicate engagement ring or a minimalist pendant. A low bezel with a thin profile is recommended for daily wear pieces, offering protection to the girdle and pavilion while maintaining a clean silhouette, and an open back or partial gallery will permit light entry to sustain the vivid blue color. For designers seeking visual impact, a diamond halo will increase apparent diameter and augment perceived color contrast, while a three stone composition with tapered side stones or step cut baguettes will emphasize the mixed cut geometry. Micro pave shoulders or a milgrain vintage setting will suit the small dimensions, allowing intricate metalwork without overpowering the gem. Given the slight inclusions, settings that control viewing angles, such as closed or partial bezels, can minimize inclusion visibility in face up presentation. For matching pairs, the stone is ideal for bespoke stud earrings or as a single accent in a cluster motif. Our craftsmen at The Natural Sapphire Company can discuss prong gauge, bezel lip thickness, and gallery design to ensure secure mounting and optimal light performance for your chosen design.
