1.37 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This round, transparent yellow sapphire weighs 1.37 carats, and measures 6.19 by 6.23 by 4.77 millimeters, presenting a well balanced proportion for both visual impact and comfortable wear. It has been cut as a mixed brilliant, combining a brilliant crown with a faceted pavilion to enhance light return and scintillation, and the finish is described as excellent polish, which confirms precise facet execution and bright, lively reflections. The color is medium light in intensity, offering a clear, fresh yellow tone that reads as a pure, sunny hue without drifting into brownish or overly intense saturation. Clarity is graded as very very slightly included when evaluated at eye level, indicating that the stone is essentially clean to the naked eye, and the documented enhancement status is none, which means this sapphire is untreated and retains its natural character. The gem is certified as Other certified Yellow, and its documented origin is Ceylon, Sri Lanka, a classic source known for producing sapphires with lively tone and attractive clarity, attributes that educated buyers often seek when assessing provenance and long term value.

From a custom jewelry perspective, this sapphire is exceptionally well suited to serve as a centerpiece because of its round shape and practical dimensions. A round mixed brilliant of approximately 6.2 millimeters across offers ideal compatibility with traditional solitaire mounts, halo designs, and three stone compositions, and it also adapts beautifully to bezel settings when protection is a priority. The 1.37 carat weight provides presence on the hand without being overpowering, making it an excellent choice for engagement rings, pendant stones, or single statement studs when set as a pair. The mixed brilliant cut helps maximize light performance in a variety of mounting styles, which means designers can confidently set the stone in a relatively low profile setting and still retain strong brilliance, or choose a higher gallery and prong setting to emphasize fire and sparkle. Because corundum registers nine on the Mohs hardness scale, this sapphire is durable enough for everyday wear, and the absence of heat or other enhancements increases its appeal to buyers who prefer naturally formed gemstones with documented origin and treatment status.

For the informed buyer who values both technical quality and design flexibility, this Ceylon yellow sapphire offers a compelling combination of natural rarity and practical design attributes. The eye level clarity grade of very very slightly included assures that inclusions will not interrupt the visual experience, and the excellent polish enhances facet reflectivity, both of which contribute to superior light return in real world lighting conditions. Origin from Sri Lanka contributes provenance that can be corroborated by standard gemological reports, and the untreated nature of the stone is a premium attribute that often commands a higher market position among collectors and bespoke jewelry clients. When planning a custom piece through The Natural Sapphire Company, consider pairing this yellow sapphire with warm metals such as eighteen karat yellow gold or rose gold to deepen and emphasize the yellow tone, or choose platinum or white gold for a contemporary contrast that makes the color appear fresher and more luminous, color interaction being a simple but powerful tool in custom design.

In practical design terms, the dimensions allow for a range of setting strategies to enhance durability and appearance, for example a bezel offers maximum protection for active lifestyles, while a four or six prong setting will maximize exposure to light for the most brilliance. If you prefer enhanced perceived size, a well proportioned halo of small white diamonds will increase visual impact without altering the intrinsic character of the sapphire, and a three stone arrangement with tapered side sapphires or diamonds can provide balance and sophistication. Our team at The Natural Sapphire Company can advise on pavilion clearance and culet considerations to ensure the mounting complements the mixed brilliant cut and preserves the stone during setting, and we can provide certified documentation that outlines weight, dimensions, origin, clarity notes, and treatment status to support insurance and resale. This natural, untreated Ceylon yellow sapphire of 1.37 carats is an excellent candidate for a custom piece that will combine enduring wearability, refined optical performance, and documented provenance, making it a smart choice for discerning buyers seeking both beauty and lasting value.
