1.80 Ct. Brown Sapphire from Ceylon (Sri Lanka)

This exquisite Other certified Orangish Brown sapphire weighs 1.80 carats, a weight that immediately places it within a premium category for transparent brown sapphires, and represents a notable balance between presence and versatility. The oval shape at 8.10 x 6.02 x 4.63 mm presents an elongated face up presentation that amplifies the perceived size while retaining comfortable proportions for bespoke settings. Transparency is exceptional, allowing light to penetrate and interact with the internal facet architecture, and the eye clean clarity grade confirmed at eye level ensures the surface and interior remain visually uninterrupted under normal viewing conditions. Origin is Ceylon Sri Lanka, a source renowned for producing sapphires with complex and desirable color expressions, and the stone is guaranteed to be untreated, no enhancement, which preserves natural crystal chemistry and affirms the stone as a collector quality gem.

The cutting style is faceted with a mixed brilliant cut, a deliberate choice that marries a step oriented crown treatment with a brilliant style pavilion, optimizing both color saturation and scintillation. The crown facet arrangement preserves and displays the orangish brown hue with controlled dispersion while the brilliant pavilion facets return concentrated flashes of white light and specular sparkle. The cutter has respected the oval proportional relationships to maintain an even spread of color from girdle to table, while the depth at 4.63 mm supports an internal geometry that avoids excessive darkening while retaining intense color intensity. Facet junctions are crisp and symmetrical, reflecting a cutting philosophy that prioritizes optical performance over maximal yield, a hallmark of high level lapidary craftsmanship. The mixed brilliant approach is particularly effective on stones from Ceylon because it allows the warm undertones to sing without losing lively brilliance.

Clarity and polish are critical to the gem s performance and longevity, and this sapphire scores highly on both counts, described as eye clean with an excellent polish. Eye clean at a standard viewing distance indicates that any inclusions present are minor and do not interrupt light pathways or visual appreciation, enabling the complete optical mechanics of the mixed brilliant design to function. Excellent polish on all facets means facet planes are free of polish lines and abrasions, which enhances mirror like reflection, strengthens fire and scintillation, and reduces the risk of surface wear in everyday settings. Color intensity is classified as intense, a grade that denotes a rich, saturated tone with strong chroma, and this orangish brown palette displays a sophisticated warmth that responds gracefully to both warm and cool metal settings. The lack of enhancement is significant, because it confirms the color is intrinsic to the crystal lattice, offering predictable behavior under different lighting conditions and maintaining long term value.

From a commercial and connoisseur perspective, the 1.80 carat weight is a defining attribute that elevates this sapphire to a premium offering within The Natural Sapphire Company portfolio. At this weight in an oval of these dimensions, the stone balances presence for a statement ring or pendant with the versatility required for refined tailoring into complex settings. Rarity is inherent in the combination of size, untreated status, eye clean clarity, intense orangish brown color, and Ceylon origin, creating a profile attractive to investors and designers alike. The Natural Sapphire Company stands behind the gem with full certification that documents its characteristics and origin, and our lapidary partners employ precision cutting and strict quality control to ensure the 1.80 carat stone meets exacting standards. For buyers seeking a technically refined sapphire where carat weight conveys premium quality rather than mere bulk, this oval mixed brilliant faceted gem offers a compelling synthesis of color, clarity, cut, and provenance, ready to be integrated into an heirloom grade design or held as a high quality specimen.
