10.45 Ct. Brown Rough Sapphire from Ceylon (Sri Lanka)

This listing describes a single, natural brown sapphire in its rough form, weighing 10.45 carats. The specimen is semi-translucent with a medium color intensity, presenting warm brown and champagne tones that allow light to transmit through interior features. Dimensions are 13.01 by 9.28 by 8.34 millimeters. The stone is uncut, cut not applicable, and retains natural crystal faces and terminations. Clarity is graded very slightly included, evaluated at eye level, with internal features that are visible under close inspection yet do not detract from overall transparency. The surface shows an excellent polish on several faces, indicative of careful handling and preparation following extraction. No enhancement has been applied to this sapphire, and provenance is Ceylon, Sri Lanka, a source long esteemed for producing a wide spectrum of sapphire colors. The Natural Sapphire Company provides this information to assist with evaluation and planning for use, whether as a collector specimen or as material for faceting and finished jewelry.

From a gemological perspective, this brown sapphire is a variety of corundum, characterized by a hardness of nine on the Mohs scale, and inherent toughness that supports everyday wear when properly set. The very slightly included clarity suggests natural growth features and mineral inclusions typical of unheated sapphires from Ceylon, and these characteristics can guide a cutter regarding orientation and potential yield. Because the stone is untreated, cutters and designers have the option to preserve its natural character, or to facet it to enhance brilliance and color saturation. When planning for cutting, factors to consider include the stone’s semi-translucence, internal zoning, and existing crystal planes, which may influence the choice between a faceted cut to maximize light return, or a cabochon to showcase color and internal texture. As a rough specimen from a recognized locality, the stone carries both gemological interest and practical considerations for any lapidary route chosen.

Aesthetically, this brown sapphire offers a restrained, earth-toned palette that reads as warm and versatile in finished applications. The combination of medium color intensity and semi-translucency produces a soft inner glow rather than a highly saturated window of color, making the material particularly well suited to designs that emphasize texture and natural beauty. In jewelry settings, the stone could be preserved as a rough statement piece or cut to produce a substantial center gem. The dimensions and weight allow for a range of outcomes, from a bold cabochon set in a protective bezel to a faceted stone intended as a focal point in a ring, pendant, or brooch. Design considerations should account for the stone’s internal features, with protective settings recommended if surface irregularities remain after cutting, and with orientation choices guided by the cutter’s assessment of color zoning and light transmission.

Traditionally, brown sapphire is associated with grounding and stability in the metaphysical literature of crystals and gemstones. Practitioners and collectors commonly attribute properties such as enhanced practicality, a strengthened connection to the earth, and increased emotional resilience to brown sapphires. The stone is often described as supporting clear judgment in matters of finance and long term planning, promoting discipline and steady progress toward goals. Brown sapphire is also linked with feelings of security and protection, and with a calming influence that aids in reducing anxiety related to change or uncertainty. In broader sapphire lore, sapphires are said to foster wisdom, clarity of thought, and honest communication, qualities that the brown varieties are believed to channel into pragmatic, action oriented outcomes. These associations reflect traditional and contemporary metaphysical uses, and should be understood as supportive beliefs rather than scientifically proven treatments.

The Natural Sapphire Company confirms that this sapphire is supplied untreated, with origin reported as Ceylon, Sri Lanka, and with an evaluation of weight, dimensions, clarity, and color intensity as stated. For purchasers considering cutting, setting, or keeping the stone as a specimen, we recommend consulting with an experienced lapidary or jewelry designer to determine the best approach given the stone’s internal structure and semi-translucent nature. Carewise, corundum is robust, but rough or partially polished surfaces may benefit from gentle cleaning with warm soapy water and a soft brush, avoiding aggressive ultrasonic cleaning until the piece has been assessed post cutting.
