10.63 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

GIA certified, this remarkable Yellow 10.63 carat cushion shape yellow sapphire sings of sunlight captured and held, each facet a stanza in a luminous poem. Measuring 12.82 x 12.61 x 7.71 mm, it wears its generous dimensions with a kind of discreet magnificence, the proportions chosen to balance presence and elegance. The modified brilliant cut allows the light to dance through a pattern of scintillating facets, producing flashes that are at once soft and exuberant, and the excellent polish ensures every reflection is clean, crisp, and true. Transparent and eye clean at normal viewing distances, this sapphire reveals no interruptions to its inner glow, and the medium intense color intensity provides a warm, honeyed yellow that is neither shout nor whisper, but a clear, confident voice. From the storied soils of Ceylon, Sri Lanka, this gem arrives with no enhancement, a natural expression of color and character, and with its GIA certification it carries the careful testimony of gemological authority.

Weight is the heart of rarity, and the 10.63 carat mass of this sapphire is a soft but undeniable drumbeat that elevates its value in ways that touch both the practical and the poetic. In a world where most sapphires are small and coy, a gem over ten carats commands a rarer fate, the size itself creating a lens through which the stone’s color, clarity, and cut are read with greater intensity. Larger sapphires that remain eye clean and untreated are uncommon, and when the origin is Ceylon, a place celebrated for producing sapphires with an ideal marriage of hue and brilliance, the combination becomes especially sought after. The physical weight translates directly into rarity because geological conditions do not often allow for such sustained growth without inclusions or color zones, and the presence of this gem in the natural, unenhanced state speaks to a fortunate confluence of time, pressure, and mineral chemistry. For the collector, the size is an investment in scale and story, for the bride or the dreamer seeking an engagement piece, it is an emblem of devotion that is physically larger and emotionally deeper, and for the connoisseur the 10.63 carat weight becomes a defining chapter in a cabinet of treasures.

Envisioned in a ring, pendant, or heirloom commission, this cushion facet arrangement becomes a stage for romance and meaning, a center of gravity around which design and life will orbit. The modified brilliant cut soaks up candlelight and sunlight alike, returning warmth and fire in measured, elegant beats, while the excellent polish sharpens each glint into a memory you can wear. The dimensions of 12.82 x 12.61 x 7.71 mm give jewelers a generous canvas for setting choices, whether a halo of fine pavé diamonds to emphasize the golden tone, a bezel that honors the stone’s history and protects its edges, or a minimalist solitaire setting that allows the sapphire to utter its own quiet poetry. At The Natural Sapphire Company we celebrate such stones not only for their gemological metrics, but for the stories they invite into being, and we can guide you through options for mounting, certification, and bespoke creation with the care of a craftsman and the heart of a storyteller. This is a sapphire that will age into legend, a sunlit token that will pass between hands and generations, its 10.63 carat presence a constant reminder that some rarities are measured in carats, and some in the luminous moments they inspire.
