1.18 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One point one eight carat cushion shape blue sapphire, with dimensions five point seven nine by five point six nine by three point eight eight millimeters, presents a rare and compelling choice for anyone seeking a gem that stands apart from the ordinary. This transparent stone is cut in a mixed brilliant style, combining the scintillation of brilliant faceting with the classic proportions of a cushion outline, and it shows excellent polish across every facet. At face up inspection the clarity is very slightly included, evaluated at eye level, which means that the inclusions do not interrupt the gem facing view, preserving a clean presentation and lively play of light. The color is described as medium in intensity, landing in that sweet spot where the hue is clearly saturated enough to read as unequivocally blue, while retaining a luminous clarity that allows sparkle and internal light return to shine. Critically, this sapphire is unenhanced, with no treatments applied, and originates from Ceylon Sri Lanka, an origin celebrated for delivering sapphires that marry attractive color with a natural, lively character. In the wider market many comparable sapphires are offered in heated or otherwise treated states to boost color stability and apparent clarity, or they are available only in smaller sizes when unheated, which makes this particular combination of size, color, and natural state notably uncommon.

When comparing this gem to other sapphires available today, the rarity of its size and color becomes clear. Unheated Ceylon sapphires that weigh above one carat and present a medium intensity blue are less frequently found than treated stones of similar looks, which means collectors and discerning buyers must often compromise between natural state and size. Many stones shown at retail are either smaller and nicely saturated, or larger but heat treated to gain that desirable tone. This stone, by contrast, offers the larger, more wearable presence that many customers want in engagement rings and statement pieces, while preserving the authenticity of an unenhanced gem. Color wise, the hue sits in a refined area of the blue spectrum where it reads as genuinely blue with subtle violet undertones from certain angles, rather than falling into over dark or inky territory that can reduce sparkle. Against Australian, Thai, and heated Ceylon stones, this example stands out for its purity and balance, it offers the kind of nuanced, natural blue that collectors prize, and it commands attention without the aggressive depth that can make a sapphire appear lifeless under varied lighting.

The mixed brilliant cut and cushion form give this gem advantages in both performance and aesthetic appeal, when compared to more common cuts and proportions. The mixed brilliant approach maximizes return of light through the crown, producing a lively, faceted fire that breathes life into the medium intensity color, this is especially important for sapphires that are not heavily saturated, because the cut can create the perception of richer color through dynamic reflections. The cushion shape, with its softly rounded corners, blends vintage charm with contemporary wearability, and the proportions captured in the stated dimensions preserve a comfortable profile on the finger, while also allowing prong or bezel settings to cradle the stone securely. Clarity described as very slightly included indicates that, unlike many commercial sapphires with more pronounced internal features, this stone will read clean to the naked eye, a trait that enhances brilliance and long term desirability. The excellent polish elevates surface finish, ensuring the facets meet smoothly and sparkle rather than scattering light, which is a contrast to mass market stones where polish and facet execution are often secondary to size or color correction through treatment.
