1.59 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This 1.59 carat oval yellow sapphire from The Natural Sapphire Company presents a precise combination of weight and proportions, measuring 7.71 x 6.14 x 4.11 mm. The gem is transparent, with a medium intense yellow hue that balances saturation and brightness for versatile wearable color. The clarity grade is very very slightly included when evaluated at eye level, which means the stone appears clean to the unaided eye while retaining natural internal characteristics that specialists appreciate for authenticity. The cut is a mixed brilliant style, and the stone exhibits an excellent polish. Importantly this sapphire has no enhancement, and its origin is verified as Ceylon, Sri Lanka, a provenance that historically commands respect from informed collectors for its fine color and crystal quality.

From a gemological and practical design perspective the mixed brilliant faceting of this oval sapphire delivers exceptional optical performance. The geometric arrangement of step and brilliant facets is engineered to maximize light return, with the crown facets acting as precise windows that gather light and the pavilion facets channeling that light back as vivid scintillation and fire. The oval outline enhances perceived size while the balanced table and pavilion depths preserve strong brilliance, so the stone exhibits lively sparkle and a pleasing pattern of light and dark facets, even under varied lighting. For an educated buyer this piece represents several value drivers, including natural unheated origin, excellent polish, eye clean clarity, and the time tested appeal of Ceylon stones. When set in a bezel or prong design the sapphire will maintain its performance and showcase its geometry, making it suitable for both modern and classic settings. The combination of technical quality and natural provenance makes this yellow sapphire a compelling purchase for collectors and bespoke designers seeking a gemstone with demonstrable gemological merit and enduring aesthetic appeal.
