0.65 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.65 carat pear shape blue sapphire exemplifies balanced proportions and refined craftsmanship from The Natural Sapphire Company, with dimensions of 6.06 by 4.57 by 2.96 mm, a mixed brilliant cut, and an excellent polish. The stone is transparent and eye clean when examined at normal viewing distance, presenting a vivid color intensity that is characteristic of fine Ceylon origin material. Enhancement disclosure is provided in full, the sapphire having been heat treated, a standard and stable treatment used to enhance color and clarity while preserving natural origin. The mixed brilliant faceting in a pear shape maximizes return of light within the limitations of its weight, producing lively internal reflections and saturated color across the table and pavilion facets. The measured proportions and precision of cut contribute to the gem appearing larger and more vivid than its carat weight alone might suggest, and the excellent polish ensures crisp facet junctions and minimal surface disturbances under close inspection.

Carat weight is one of the primary determinants of both perceived rarity and market value for sapphires, and a 0.65 carat stone occupies an important position within the range of collectible sizes. At this weight there is a balance between accessibility and scarcity, with fewer gems available that combine vivid color intensity, eye clean clarity, and provenance from well known Sri Lankan deposits. Weight is not linear in value, because price per carat typically increases as stones move above certain thresholds, and the cost to produce a clear, saturated sapphire of consistent color intensifies as cutters seek to retain weight from rough material while removing inclusions and undesirable color zoning. For this reason a 0.65 carat sapphire with the attributes described often represents a disproportionate investment in skilled cutting and selection relative to lower grade material of similar weight. In practical terms the weight of this stone reflects both the geological rarity of material that can achieve vivid color in small dimensions and the human effort required to transform rough crystal into a well proportioned, eye clean pear shape.

The relationship between the gem weight and its dimensions is an important consideration when assessing how the stone will present in jewelry, and when evaluating market value relative to size. The dimensions of 6.06 by 4.57 by 2.96 mm indicate a relatively deep pavilion for a pear shape, which supports saturation of color and allows the mixed brilliant faceting to return strong flashes of blue even at modest table size. The depth contributes to weight without proportionally increasing surface area, so a sapphire with these proportions can appear intensely colored and compact on the finger while still reflecting the material rarity associated with its carat weight. Clarity is eye clean at normal viewing distance, which preserves transparency and minimizes the need for intrusive repair or filling treatments. The heat treatment applied is stable and widely accepted within the trade, and it serves to optimize color while maintaining structural integrity. Polish quality is excellent, which enhances luster and contributes to perceived value by improving light return and surface finish. Collectors and designers often value the combination of vivid color intensity, eye clean clarity, and precise cut more highly than carat weight alone, and this sapphire demonstrates how a well chosen 0.65 carat gem can fulfill both aesthetic and technical criteria.

Provenance from Ceylon Sri Lanka adds an additional layer to the gem story, since material from that region is often sought for its lively tone and vibrant saturation. Origin does not alone determine value, yet when paired with a measured weight and the gemological parameters described it helps inform market positioning and desirability. Disclosure of enhancement, in this case heat treatment, is integral to accurate evaluation, and buyers are advised to consider all of the documented factors when assessing long term value. In finished jewelry the sapphire sited at 0.65 carat is well suited to solitaire designs, halo settings that accentuate apparent size, or as an accent in multi stone compositions where color consistency and clarity are essential. The Natural Sapphire Company provides full transparency on origin and treatment, and the detailed specifications for this pear shape stone allow jewelers and connoisseurs to assess mounting options, expected visual impact, and comparative value with confidence. Overall the 0.65 carat weight of this pear shape blue sapphire contributes materially to its rarity and to the economic considerations that determine price, while the gem quality attributes ensure that it performs visually beyond what a simple numerical weight might imply.
