2.40 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 2.40 carat oval blue sapphire is presented by The Natural Sapphire Company with precise dimensions of 8.39 by 6.11 by 5.59 millimeters, reflecting careful cutting and proportioning for balanced optical performance. The gem is fashioned in an oval profile with a mixed brilliant cut, combining a faceted crown designed for scintillation with a pavilion that optimizes light return. Clarity is described as very slightly included, evaluated at eye level, which translates to minor internal characteristics that do not materially detract from the gems overall appearance to the unaided eye. Color is of vivid intensity, delivering a deep and saturated blue that remains lively across viewing angles, and the polish has been assessed as excellent, indicating well executed facet junctions and smooth facet surfaces. The sapphire originates from Ceylon Sri Lanka, a source long regarded for producing stones with attractive saturation and lively tone, and the material has been heat treated, a stable and widely accepted enhancement that improves color and clarity while remaining permanent under normal wear conditions.

The vivid blue color of this sapphire exhibits a strong hue with balanced saturation and medium to medium deep tone, producing a color that reads as distinctly blue without appearing overly dark, which enhances both face up appearance and the perception of depth. The mixed brilliant cut contributes to a lively interplay of brilliance and scintillation, with the crown facets dispersing light and the pavilion facets configured to return a strong proportion of incident light back to the viewer. Because the stone is transparent with very slight inclusions at eye level, light transmission remains high, supporting clean flashes of brilliance and allowing color zoning to be minimal in typical viewing conditions. The excellent polish accentuates facet crispness and contributes to the gem appearing clean and sharp in hand, while the oval outline lends a classic yet versatile silhouette that works well in a variety of mounting styles.

This sapphire is inherently versatile and suitable for both casual and formal settings, offering a presence that is refined enough for elegant evening jewelry while remaining robust and approachable for everyday wear. In informal contexts the stone pairs well with understated designs, such as low profile solitaires and simple bezel settings that protect the girdle and pavilion, while in formal contexts the same gem can serve as the focal point in halo arrangements, three stone compositions, or bespoke pieces that showcase the vivid color and balanced proportions. The dimension and oval shape provide a flattering orientation on the finger or as a pendant, elongating the visual line and creating a sense of proportion without dominating complementary design elements. Recommended metal pairings include platinum and 18 karat white gold to emphasize cool blue tones, or 18 karat yellow gold and 18 karat rose gold to introduce warm contrast and a more classic or vintage aesthetic. For clients desiring practicality, settings that secure the gem with robust prongs or a partial bezel will preserve the stone under frequent wear, while designs that raise the crown may be selected for pieces intended primarily for special occasions to maximize light interaction.

From a maintenance and certification perspective, this sapphire benefits from the inherent durability of corundum, which rates a nine on the Mohs hardness scale, providing excellent resistance to everyday abrasion. Heat treatment is a stable enhancement, and it does not impose special limitations on routine care, however care should be taken to avoid prolonged exposure to strong chemicals and extreme thermal shock. Cleaning with warm soapy water and a soft brush or professional ultrasonic and steam cleaning under the guidance of a jeweler is appropriate for heat treated sapphires, and periodic inspection of the setting is advised to ensure the gem remains secure. The Natural Sapphire Company stands ready to provide detailed gemological documentation upon request, and our gemologists can advise on mounting options, custom design, and certification to support insurance and appraisal needs. This 2.40 carat Ceylon blue sapphire is presented as a durable, visually compelling gem, suitable for a wide range of jewelry applications, offering both the practical qualities expected of a daily wearable stone and the refined character desired for formal and heirloom pieces.
