5.15 Ct. Pink Sapphire from Ceylon (Sri Lanka)

At The Natural Sapphire Company we present a beautiful transparent 5.15 carat cushion shape pink sapphire, measuring 10.46 x 7.36 x 6.68 mm, cut with a mixed brilliant pavilion and exhibiting a clarity grade of very slightly included, evaluated at eye level. This Ceylon Sri Lanka origin sapphire has a faint color intensity and an excellent polish, and it is completely natural with no enhancement. The cushion shape combined with the mixed brilliant cutting style balances broad, luminous flashes and lively scintillation more effectively than step cut cushions or overly shallow cuts, delivering an elegant play of light that stays even under movement. Because it is transparent and only very slightly included, evaluated at eye level, the stone returns light with a purity and evenness that many darker or heavily included pink sapphires cannot match, while its excellent polish sharpens facet junctions so each flash of brilliance is crisp and well defined.

Compared directly to other gemstones in the same color family, this Sri Lankan pink sapphire offers distinct advantages in reflective quality and durability. Against heat treated sapphires and oiled stones, an untreated Ceylon sapphire like this one transmits light without the diffusion or masking effects that enhancements can introduce, producing a clearer, more honest brilliance. Compared to rubies, which are the same mineral species but often deeper in tone, the faint pink intensity of this sapphire allows greater internal reflection and a brighter overall appearance in jewelry settings. Against pink spinel and pink tourmaline, which generally have lower refractive indices and softer sparkle, this sapphire returns more lively scintillation and stronger contrast, while also offering superior hardness for everyday wear. Compared with morganite, which can show a warm glow but a more subdued flash, this mixed brilliant cushion delivers sharper flashes and a livelier presence on the finger.

For buyers seeking a natural, well cut, and well polished pink sapphire that maximizes light return without relying on enhancement, this 5.15 carat Sri Lankan cushion is a standout choice. Its proportions and mixed brilliant faceting make it more scintillating than many competitors in the marketplace, and its untreated nature preserves a clarity and light transmission that conveys true value and rarity.
