7.79 Ct. Yellowish Brown Sapphire Crystal from Ceylon (Sri Lanka)

This listing describes a natural, semi transparent yellowish brown sapphire weighing 7.79 carat, with dimensions 19.70 x 7.50 x 6.50 mm, presented in a rough crystal cut that preserves much of the original crystal habit. The stone displays a medium color intensity that sits in an attractive range for collectors and designers who appreciate warm, earthy sapphire hues. The cut is various in shape, and the surface has been given an excellent polish that enhances light return from the crystal planes despite the rough style of the cut. Clarity is graded as included, evaluated at eye level, which means the stone contains visible inclusions that are typical for natural corundum and that contribute to the gemographic story of the piece rather than detract from it. Enhancement is none, the sapphire is untreated, and the origin is Ceylon Sri Lanka, a source historically renowned for producing sapphires with fine crystallography and characteristic luster.

From a gemological perspective this sapphire is of interest for several reasons. As a corundum variety, its color results from natural trace elements and structural features formed during crystallization, and the yellowish brown tone is consistent with iron related chromophores in the crystal lattice. Because the gem is unenhanced, collectors who prioritize natural color and provenance will value this specimen more than comparable heated or otherwise treated material. The included clarity grade indicates the presence of internal features that can affect light transmission and personality, and for an educated buyer these inclusions impart a fingerprint of origin and authenticity. The semi transparent nature allows for a warm glow and internal depth when set, while the medium color intensity keeps the stone versatile in both classic and contemporary jewelry designs. The excellent polish means facets and crystal faces are well finished, offering pleasing surface brightness and touch, even as the overall cut retains a naturalistic, rough crystal aesthetic.

The origin, Ceylon Sri Lanka, adds meaningful context for valuation and desirability. Ceylon sapphires are historically prized for their clean crystal forms and a wide palette of colors, and provenance from Sri Lanka is often associated with sound market recognition and collector confidence. For buyers concerned about long term value, untreated material from well known localities tends to hold and appreciate better than similar stones that have undergone enhancement. Design wise this stone is ideal as a statement center in a bespoke ring, a prominent pendant, or as a museum style specimen for a cabinet. Because of its length and profile it can be oriented to emphasize symmetry or to follow an organic design language, and settings that protect the edges, such as bezel or secure prongs, will both showcase and preserve the stone. The combination of substantial carat weight, unenhanced natural color, and Ceylon origin makes this sapphire attractive to connoisseurs and designers seeking authenticity and natural character in their pieces.

At The Natural Sapphire Company we document provenance and treatment history carefully, and we welcome requests for independent gemological reports or additional imagery under controlled lighting to assist with purchase decisions. We can advise on mounting options that best protect and display the sapphire, and we offer guidance on cleaning and care, recommending gentle warm soapy water and soft brushes for routine cleaning, and professional inspection prior to any ultrasonic or steam cleaning given the natural inclusions. For an educated buyer this unenhanced 7.79 carat Ceylon sapphire represents a well documented, characterful example of natural corundum, combining demonstrable origin, intrinsic color, and a surface finish that respects the stones crystal identity, and The Natural Sapphire Company stands ready to provide further technical details and certification options to ensure a confident acquisition.
