3.50 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 3.50 carat cushion shape blue sapphire measures 8.92 by 8.85 by 4.79 millimeters, and has been fashioned with a mixed brilliant cut to balance color saturation and light return. The cutter has combined brilliant style crown facets with a more pavilion oriented step pattern to broaden the face up and to preserve the stone weight while enhancing scintillation. The excellent polish delivers crisp facet junctions and controlled light leakage, which allows the intense color intensity to present as a deep, vivid blue across the table. Clarity is graded slightly included at eye level, meaning small natural inclusions are present but do not detract from the gem when mounted. Origin is Ceylon Sri Lanka, a source known for lively blue tones, and a standard heat treatment has been applied to stabilize color and improve transparency. In hand the stone exhibits moderate pleochroism, shifting between a vibrant medium blue and a deeper velvety blue depending on orientation, a characteristic that reinforces the depth and complexity of this sapphire.

As an heirloom candidate this sapphire combines material durability and considered craftsmanship, key attributes for an object intended to survive generations. Corundum rates nine on the Mohs scale, making it exceptionally resistant to wear and suitable for everyday settings when set with protective gallery work or a low profile bezel. The cushion outline is a timeless silhouette that sits well in classic solitaire or halo mounts, and the mixed brilliant faceting will continue to flash attractively under varied lighting conditions. The slight inclusions serve as a natural fingerprint that attests to authenticity and provenance, and the Sri Lankan origin adds a narrative provenance that increases desirability over time. With routine professional cleaning and occasional inspection of the mounting the stone will retain its face up appeal, and if future tastes change the substantial dimensions and balanced pavilion proportions allow for sensitive re cutting without significant loss of presence. At The Natural Sapphire Company we provide detailed documentation on origin treatment and cutting, and we can advise on settings that protect the stone while showcasing its intense color, ensuring this cushion blue sapphire becomes a durable, verifiable, and cherished generational heirloom.
