3.12 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This vivid blue cushion shape sapphire began its journey deep within the ancient geology of Ceylon Sri Lanka, a land long celebrated for producing some of the world most enchanting corundum crystals. From time worn river gravels in the Ratnapura region to the careful hands of artisanal miners who follow generations of knowledge, nature first shaped this stone over millions of years, compressing elemental iron and titanium within aluminum oxide to yield that unmistakable blue. The Natural Sapphire Company partners with trusted sources in Sri Lanka to honor that lineage, and this gem arrives C.Dunaigre certified Vivid Blue, a designation that attests to both its pedigree and its extraordinary color. Weighing 3.12 carat, the gem measures 8.67 x 7.20 x 5.27 mm, cut into a cushion shape with a mixed brilliant facet arrangement, evaluated as eye clean at eye level, with vivid color intensity and an excellent polish, and enhanced by a traditional, stable heat treatment that deepens and stabilizes the blue without compromising transparency. Holding this sapphire, you can almost sense the rivers and the monsoon winds that witnessed its birth, and you can feel the centuries of admiration that have made Ceylon sapphires a symbol of prestige and devotion.

The sparkle this sapphire delivers is a direct conversation between its internal crystal structure and the skillful geometry applied by the cutter, a conversation that results in a light performance few gems can match. As a natural corundum, the stone has a trigonal crystal lattice and a refractive index that is appreciably higher than many common gems, allowing light to bend and reflect with remarkable intensity. Trace elements of iron and titanium create the blue hue while also contributing to the sapphire ability to interact with light in layered ways, producing subtle pleochroism which lets different angles reveal slightly different depths of blue. The mixed brilliant cut applied to the cushion shape is deliberate, it balances the soft, elegant outline of the cushion with a modern array of crown and pavilion facets designed to maximize total internal reflection, returning brilliant white flashes as well as selective blue scintillation. The pavilion facets act as mirrors, sending light back through the richly colored crown where the angles fragment and scatter rays, creating lively sparkle and a textured flash pattern that feels both lively and refined. Because the stone is transparent and eye clean, there are no visual interruptions to that internal light play, allowing consistent, uninterrupted brilliance from the table through the crown. The excellent polish enhances every facet edge, sharpening light return and giving each flash a crisp, lively character, while the heat treatment refines the color to that vivid blue grade, intensifying saturation and depth without altering the gem inherent optical physics. In short, this sapphire does not merely shine, it performs, with an intensity and complexity that distinguishes it from paler or more included stones.

To the person who wears it, this sapphire offers more than technical excellence, it carries story, culture, and a promise of enduring beauty. Historically Ceylon sapphires have adorned temples, crowns, and ceremonial jewelry, regarded as tokens of protection, wisdom, and fidelity, and when set into a ring or pendant this 3.12 carat cushion evokes that lineage in a way that feels both timeless and personal. The Natural Sapphire Company stands behind this gem with careful documentation and ethical sourcing, ensuring that the same care invested in its mining and cutting extends to your ownership experience. Practical benefits accompany its visual poetry, the robust nature of corundum means excellent durability for everyday wear, while common care practices involving a soft brush, warm soapy water, and occasional professional inspection will keep the polish and sparkle at their peak. The heat treatment noted on the accompanying report is a widely accepted process in the trade, applied to enhance color stability and to reveal the gemstone best potential, and the C.Dunaigre certification gives you third party assurance of the gem identity and grade. Imagine a bespoke setting that allows the table to catch light at every movement, imagine the vivid blue deepening under evening lamps and brightening in daylight, imagine gifting a piece that communicates history, place, and intention.
