1.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing describes one transparent blue sapphire, weighing 1.13 carat, cut in an oval shape, with dimensions of 7.60 x 5.72 x 3.24 mm. The stone is fashioned with a mixed brilliant cut, combining a faceted crown designed for scintillation with a pavilion arrangement that enhances return of light. The clarity grade is very very slightly included, evaluated at eye level, indicating that the stone presents minimal inclusions when viewed without magnification. The color intensity is light, revealing a delicate Ceylon blue characteristic of Sri Lanka, and the surface finish is described as excellent polish. Enhancement status is none, the stone has not been treated, and its stated origin is Ceylon, Sri Lanka. The Natural Sapphire Company is the source of this gem, and these attributes reflect the gemological observations recorded at the time of listing.

The mixed brilliant cut in this example is instrumental in the stone's optical performance. By combining larger upper crown facets with a carefully faceted pavilion, the cutter has balanced fire and brightness, allowing flashes of light to break into small, lively scintillations while maintaining overall face up brightness. The relatively shallow pavilion depth of 3.24 mm, in relation to the table and crown proportions, contributes to a broad, reflective table that reads larger on the finger than the carat weight alone might suggest. The excellent polish reduces surface light scatter, improving contrast between facet reflections and delivering a cleaner, sharper appearance to each flash of light. The very very slightly included clarity grade preserves transparency, permitting more direct passage of light through the body of the stone, which enhances perceived brilliance and saturation of the blue tone.

When compared to more common blue gemstones, this sapphire presents a distinct balance of attributes that allow it to stand out. Against diamond, sapphires exhibit a lower refractive index, which results in less intense dispersion and fire, however sapphires compensate with saturated body color and durable, polished facet architecture that deliver strong lively scintillation without the high contrast flashes typical of diamond. Compared with blue topaz and aquamarine, which often display paler tones and greater pleochroic variability, this Ceylon sapphire offers a more vivid blue even at light intensity, and its mixed brilliant cut preserves color while maximizing light return. Unlike heat treated sapphires or other enhanced stones, the absence of enhancement in this gem preserves the natural distribution of color and inclusions, attributes which collectors and connoisseurs often value for authenticity and long term stability. The combined effect of cut, clarity, and natural color produces a type of brilliance that is less about extreme fire and more about a refined, evenly distributed luminous quality that reads as elegant and natural in jewelry.

The origin from Ceylon, Sri Lanka, contributes to the gemological context, as Ceylon sapphires are renowned for their light to medium blue tones that exhibit clarity and a soft, appealing saturation. The lack of enhancement confirms that this tone and clarity are intrinsic to the crystal, rather than the result of treatment. For practical considerations, a 1.13 carat oval with dimensions of 7.60 x 5.72 x 3.24 mm will set comfortably in a range of ring and pendant designs, where the oval outline and mixed brilliant cutting style will interact well with both open and closed settings. The Natural Sapphire Company provides documentation of the stated properties, and this sapphire is suitable for those seeking a naturally formed Ceylon blue with measured brilliance, verified clarity, and an excellent polish, qualities that contribute to both visual appeal and long term wearability.
