4.81 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This transparent purplish blue sapphire weighs 4.81 carats, and is presented in an asscher octagon shape with faceted cutting. The gem measures 9.63 by 9.41 by 5.26 mm, and displays a balanced profile that complements the asscher style. Clarity is graded as very slightly included, evaluated at eye level, which yields an attractive degree of transparency and minimal visible inclusions. Color is described as medium intensity purplish blue, a tone that reads as refined and versatile under a range of lighting conditions. The stone has received heat treatment, a common and stable enhancement practice for sapphires, and benefits from an excellent polish that accentuates its step facets and overall light performance. This sapphire is sourced from Ceylon, Sri Lanka, a region long noted for producing sapphires with lively color and even saturation.

The weight of 4.81 carats is a primary factor in the gemologic and market significance of this sapphire. Sapphires become progressively rarer as size increases, and stones approaching the five carat mark are encountered far less frequently than small or medium sized gems. The carat weight influences the stone in multiple ways, including the potential per carat value, the demand among collectors and designers, and the perceived rarity. In practical market terms, a sapphire that is firmly in the multi carat range attracts a price premium compared with smaller stones of comparable color and clarity, because larger transparent material with even color and minimal inclusions is inherently scarce. The 4.81 carat weight places this gem in a category where both aesthetic presence and investment interest are heightened.

Beyond monetary considerations, the near five carat weight materially affects the optical characteristics and design possibilities for this sapphire. The asscher cut, with its concentric step facets and open table, benefits from the available weight by allowing for deeper stepped pavilion facets and a generous table surface that showcases the stone center. The proportions at 9.63 by 9.41 by 5.26 mm are well suited to the asscher approach, providing good face up presence while maintaining a depth that supports even color distribution and strong light return. The very slightly included clarity allows the asscher facets to develop clear geometric reflections, and the excellent polish enhances facet contrast and overall brilliance. For jewelry applications, this weight and shape are versatile, working equally well as a centerpiece in an elegant solitaire ring, as the focal point of a bespoke pendant, or as a prominent stone in a tailored three stone composition.

Provenance and treatment history further contextualize value and collectibility. Origin Ceylon, Sri Lanka, contributes to the gemstone narrative, as material from this region is historically associated with lively tone and appealing clarity. Heat treatment is noted as the enhancement method, and when performed as a standard treatment for sapphire, it is both stable and widely accepted within the trade. The combination of medium purplish blue color, eye level very slightly included clarity, excellent polish, and substantial 4.81 carat weight results in a gemstone that is rare within the market for transparent sapphires of similar hue and cut.
