1.65 Ct. Blue Spinel from Ceylon (Sri Lanka)

This 1.65 carat cushion shape blue spinel from Ceylon Sri Lanka is a study in precision cutting and natural color saturation, supplied by The Natural Gemstone Company. The gem measures 6.78 x 5.79 x 4.85 mm and is faceted in a mixed brilliant style, combining a well proportioned brilliant crown with a carefully calibrated pavilion that uses a mix of brilliant and modified step facets to optimize return of light. The cushion outline displays soft rounded corners and a balanced crown height, the table is sized to emphasize the stones vivid blue saturation while preserving internal depth, and the facet junctions are sharply defined, producing crisp facet contrast and controlled scintillation across the surface. Clarity is graded as very very slightly included when evaluated at eye level, with minute pinpoint inclusions that do not disrupt overall transparency or interfere with clean facet reflections. The polish is excellent, yielding high mirror like facet surfaces that enhance both luster and the gems internal flash, and the stone is offered in truly natural condition with no enhancement, the rich vivid color intensity arising from native zoning and trace element chemistry typical of Ceylon spinel.

From a durability and wearability perspective this spinel rates 8 on the Mohs scale, placing it above common jewelry materials such as quartz and topaz, and below corundum which registers at 9, and diamond at 10. Spinels also benefit from an isometric crystal system with no true cleavage, which improves resistance to splitting under impact compared with gems that have pronounced cleavage planes. For daily wear applications including rings and bracelets the 8 Mohs hardness combined with good toughness and the stones compact dimensions make it an excellent candidate, though protective setting design such as low profile bezels or secure multi prong settings are recommended for high wear environments to minimize edge chipping. This cushion blue spinel presents an exceptional balance of natural vivid color, technical cutting finesse, and practical durability, and The Natural Gemstone Company presents it as a premium, unenhanced Sri Lankan spinel suitable for fine jewelry that demands both aesthetic refinement and long term performance.
