The color of this sapphire is the defining attribute, a vivid blue that reads as true Royal Blue with depth and saturation that strongly influences value, When discussing sapphire color with a collector or an informed buyer, three interrelated variables are essential, hue, tone, and saturation, Hue describes the primary wavelength of color, in this instance a pure blue with minimal green or violet admixture, Tone describes the lightness to darkness, and this gem sits in a range that is deep enough to be richly saturated, while maintaining transparency and brilliance, Saturation or intensity is vivid, which implies a high concentration of color that is neither brownish nor muted, The vivid intensity in a Ceylon origin sapphire is particularly desirable because it combines the island mines characteristic velvety depth with a bright, lively expression of blue, The mixed brilliant facet arrangement helps the stone display its color uniformly across the table, while providing flashes of lighter blue that enliven the surface, The result is a bold color that translates visually as confidence and presence, making the gem a compelling choice for an individual seeking an object that communicates personal power and distinction.

From a technical valuation perspective, the 3.57 carat weight is at a threshold where size becomes a key factor in both visual impact and market positioning, Oval shapes tend to appear larger face up than many equivalent round stones, which enhances perceived size without sacrificing light performance, The dimensions of 10.10 by 8.01 by 5.66 mm produce a pleasing table to depth relationship for this cut style, A well controlled pavilion depth and mixed brilliant upper girdle facets deliver strong light return, The clarity grade of very very slightly included indicates inclusions that do not detract from the stone when set and viewed in everyday use, In the trade, heat treatment is an accepted and stabilized practice, it improves color and clarity in many Ceylon sapphires, and when fully disclosed and certified it does not reduce desirability for most collectors, The documented Sri Lankan origin brings with it a recognized market preference for certain blue nuances that are distinct from other localities, which can affect both desirability and price, For a discerning buyer, the combination of a reputable independent certificate, a vivid Royal Blue color, eye clean clarity, and excellent polish presents a transparent investment in both aesthetic and gemological quality.

When considering setting and long term ownership, the stone is ideal for a signature ring or a pendant where the strong color is the focal point, For metal selection, platinum or a heavier weight white gold will emphasize the pure blue, while yellow gold will introduce a warm contrast that can enrich the stone visually, Halo or bezel settings will protect the stone and enhance apparent size, a simple solitaire will place full emphasis on the color and the precision of the cut, The Natural Sapphire Company can assist with bespoke design recommendations that respect the stone dimensions and optical characteristics, Our approach is to match setting geometry to a gem so that the table face up displays maximum color saturation and light return, Beyond fashion, this sapphire functions as a powerful symbol, its rich bold color speaks to personal power and distinction, For an educated buyer who values documented origins, transparent treatment disclosure, and superior cutting and polish, this C.Dunaigre certified Ceylon sapphire offers an authentic, verifiable, and enduring choice.
