1.40 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.40 carat round blue sapphire presents a precise combination of weight, proportions, and optical clarity, making it an outstanding addition to a high end gemstone collection. The stone measures 6.61 x 6.51 x 4.08 mm, with a mixed brilliant cut that optimizes light return while retaining a refined pavilion profile. The cut blends a brilliant faceted crown with a faceted pavilion that moderates dispersion and enhances depth, producing a lively play of facets without compromising the sapphire character. The stone is transparent throughout, and the proportions as measured provide a pleasing face up presence in this carat range, allowing the intense color to register clearly under standard viewing conditions.

Color remains the primary determinant of desirability for blue sapphire, and this example displays an intense blue saturation that is both vivid and well balanced. The hue sits in the classic range associated with fine Ceylon sapphires, with blue tones that are neither overly dark nor overly gray, preserving vibrancy in direct and diffuse lighting. The intensity of color is consistent from the crown to the girdle, and the mixed brilliant cut helps to distribute that color evenly across the table while producing attractive scintillation. There is a clarity to the blue that supports its lively appearance, and the gem presents a clean, focused color that will respond well to a variety of mounting styles without losing saturation.

Clarity has been graded as very very slightly included evaluated at eye level, and the gem is effectively eye clean in normal viewing. Inclusions are minimal and do not interrupt the overall transparency or the face up presentation, allowing the gemstone to display its inherent brilliance. The polish is excellent, which contributes to crisp facet junctions and strong light return, and the absence of surface disturbance supports a bright, reflective face up. Importantly, the sapphire has no enhancement, a characteristic that adds to its rarity and appeal for collectors who prioritize untreated natural material. The origin is recorded as Ceylon, Sri Lanka, a provenance that is historically associated with high quality, finely colored sapphires and that often carries significance for connoisseurs and assemblages focused on regional origin.

As a piece for a curated collection, this sapphire offers a balance of tangible metrics and aesthetic performance. Its 1.40 carat weight and round shape make it versatile for display in a loose gemstone cabinet or for incorporation into a custom high end jewel, while the combination of intense natural color, very very slight inclusions, excellent polish, and lack of enhancement supports its standing as a collectible natural specimen. The Natural Sapphire Company offers this sapphire as part of a selection that emphasizes documented origin and untreated material, and the gem will appeal to collectors seeking a Ceylon sapphire with demonstrable clarity and lively color. For those building a focused assortment of natural sapphires, this gem represents a measured and enduring example of Sri Lankan material that balances visual allure with transparent specification.
