0.63 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This gemstone is a precisely fashioned round shape blue sapphire weighing 0.63 carat, with exact dimensions of 5.08 by 5.08 by 3.14 millimeters. The cutter employed a mixed brilliant cut to balance intense color saturation with optimal light return, using a brilliant style facet arrangement on the crown combined with a modified pavilion faceting pattern that deepens apparent color when viewed face up. The crown presents a well centered table, six star facets, and a symmetrical distribution of upper girdle facets that direct light into the pavilion mains, while the pavilion features carefully angled mains and lower girdle facets that control internal reflection and scintillation. The girdle is proportioned to preserve weight without causing light leakage, and the culet is minimized to maintain a continuous field of blue across the table. The excellent polish is evident in the crisp facet junctions and mirror like facet planes, which contribute to lively contrast and crisp facet reflections when the stone is examined under both daylight and controlled light sources.

At face up inspection the sapphire is transparent with a clarity grade described as very slightly included, assessed at eye level, indicating small, well dispersed inclusions that do not interrupt the overall visual transparency or the stone s ability to transmit and reflect light. The color is classified as intense in color intensity, presenting a deep, vivid blue with the hallmark Ceylon element of brightness that permits a bluish violet nuance in certain lighting angles, while retaining a strong saturation that reads as decidedly blue in direct northern daylight. This specimen is untreated, with no enhancement, which is a significant attribute for connoisseurs and collectors who value natural color origination. Origin is Ceylon Sri Lanka, a source known for producing sapphires that combine clarity and lively blue tones, and this provenance contributes positively to both aesthetic and market considerations. The cutter s choice to preserve weight while producing a balanced pavilion depth results in an optimal crown to pavilion ratio for this size, enhancing face up color without unnecessary darkening or windowing.

Beyond the measurable specifications this sapphire s rich, bold color functions as a tangible emblem of personal power and distinction, delivering presence in a manner that is both refined and resolute. In jewelry design terms the stone s 5.08 millimeter diameter and intense saturation make it ideal as a solitaire center in a classic four or six prong setting where the table dimensions will present a commanding, saturated blue face, or as a focused accent within a halo of white gemstones to amplify perceived color contrast and brilliance. For a modern statement the mixed brilliant cut responds very well to polished platinum or 18 carat white gold because the cool metal tones maximize color contrast, while yellow gold settings can warm the presentation for a more vintage or regal expression. For bespoke mounting precision is recommended, with slightly elevated prongs to allow light entry beneath the pavilion, and secure bezel alternatives for everyday wear without sacrificing the stone s optical performance. When you choose this natural Ceylon sapphire through The Natural Sapphire Company you are selecting a gem that combines exacting lapidary craft, natural, untreated color, and an intrinsic symbolism of authority and uniqueness, all of which appeal to buyers who require technical excellence and aesthetic distinction in equal measure.
