0.86 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent pear shape blue sapphire weighs 0.86 carat, and measures 7.10 x 4.74 x 3.17 mm. The gem presents a delicate light blue evenness with light color intensity, and displays excellent transparency across its form. Cut in a pear outline, the stone combines the graceful teardrop silhouette with a precise mixed brilliant faceting scheme that balances fire and brilliance. Origin is Ceylon Sri Lanka, and the sapphire has been heat treated to enhance its color and overall clarity. The clarity grade is described as very very slightly included when evaluated at eye level, and the finish is an excellent polish which contributes to the clean presentation and high surface reflectivity. These attributes produce a refined appearance suitable for a variety of fine jewelry designs, and they align with the standards of The Natural Sapphire Company.

The mixed brilliant cut employed in this pear shape is engineered to maximize light play through a carefully considered geometry of crown and pavilion facets. The crown presents a series of small, precisely angled facets that disperse incoming light and introduce scintillation across the table. The pavilion features a combination of kite and star shaped facets that act together to return light through the crown, increasing overall brightness and contrast. The pear outline requires asymmetric planning to maintain optical balance from the rounded end to the pointed tip. Facet orientation and indexation were executed to ensure that light entering the gem encounters multiple internal reflections before exiting, producing lively flashes and a pleasing pattern of light and dark areas. The mixed brilliant approach in this stone emphasizes both facet brilliance and a controlled degree of fire, yielding a dynamic yet elegant visual performance in a compact 0.86 carat weight.

The very very slightly included clarity grade, assessed at eye level, indicates that the sapphire contains only minor internal features that do not materially interrupt its optical performance. These inclusions remain inconspicuous, and when combined with the excellent polish they have negligible effect on the gem s apparent brightness and transparency. Dimensional proportions of 7.10 x 4.74 x 3.17 mm support stable light return and practical setting depth, permitting secure mounting while maintaining a balanced face up presentation. The heat treatment applied is a standard, widely accepted enhancement that stabilizes and refines the stone s color distribution without compromising structural integrity. From a craftsmanship standpoint, the cutting and finishing decisions yield a stone that performs well under varied lighting conditions, offering a consistent light play that is especially noticeable under directional and natural light sources.
