1.05 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This beautiful transparent yellow sapphire weighs 1.05 carats, and has a classic round shape that measures 6.30 by 6.26 by 3.62 millimeters. The gem has been fashioned with a mixed brilliant cut, which combines the scintillation of a brilliant style crown with complementary pavilion facet arrangements to balance light return and color saturation. At an eye level clarity grade of slightly included the stone exhibits small, well healed inclusions that do not distract from its face up appearance, and it displays an intense yellow color intensity that is both vivid and lively. The polish is excellent, giving the pavilion and crown facets crisp facet junctions and allowing maximum sparkle. The sapphire has undergone routine heat treatment to enhance its color and clarity, and its documented origin is Ceylon, Sri Lanka, a source renowned for producing yellow sapphires with bright, sunny hues. The Natural Sapphire Company has fully examined and graded this gem as part of our commitment to transparent provenance and quality.

The mixed brilliant cut of this round sapphire has been selected to make the most of the rough material, optimizing both brilliance and color. With a diameter near 6.3 millimeters and a depth of 3.62 millimeters the proportional depth falls at approximately 57.6 percent, a range that tends to favor even light distribution while maintaining face up brightness. The crown facets are cut to return lively flashes of white light and fire, while the pavilion facet arrangement complements the color plane so that the yellow saturation is evenly presented across the table. Excellent symmetry and an excellent polish mean that light passes cleanly through the stone without unnecessary scattering, and the mixed cut also helps mask the very small internal characteristics that place this sapphire in the slightly included clarity category. For buyers who appreciate the interplay between cut and color, this gem illustrates how thoughtful cutting can elevate a natural material into a jewel with both visual impact and technical merit.

The clarity description of slightly included when evaluated at eye level is an important point for an informed buyer to understand, because it describes what you will see in normal viewing conditions. Slightly included in this context means the stone contains minute crystals or slender needle like inclusions that are visible under close observation, but they do not significantly weaken the apparent transparency or detract from the gem s brilliance. These inclusions are typical of natural corundum and can even act as internal fingerprints that affirm natural origin. Corundum has a hardness of nine on the Mohs scale, making sapphires exceptionally durable for daily wear when set in rings or pendants, and the excellent polish on this stone further reduces the likelihood of surface wear. Gemological properties of sapphire that benefit the wearer include a refractive index in the range that produces strong light return, and a modest birefringence which is unlikely to affect the apparent color in a well cut round stone. The heat treatment applied to this sapphire is a stable, industry accepted enhancement, performed to reduce certain inclusions and to intensify a desirable yellow tone, and it should be considered a standard refinement that increases the gem s market appeal.

The journey of this yellow sapphire from Ceylon to the market is a narrative that underlines both ethical sourcing and lapidary craft. In Sri Lanka the gem likely originated as alluvial corundum found by local miners working river gravels and secondary deposits, a traditional source that has produced fine sapphires for centuries. From the initial discovery the rough would have been assessed for color zoning, crystal form, and inclusions, then routed to skilled cutters who understand how to release the best color from a yellow rough while minimizing weight loss. The heat treatment that was performed to enhance hue and clarity was carried out under controlled conditions by experienced heat technicians, a process that is reversible to neither the market nor to ordinary wear, and which is accepted by gemologists as a stable enhancement. After cutting and polishing the finished gem was inspected by our gemological team, measured for precise dimensions, and graded for color, cut, clarity, and polish. The Natural Sapphire Company maintains direct relationships with our source communities and with reputable lapidaries so that every sale is accompanied by clear information on origin and treatment, allowing our clients to make informed decisions.

For the educated buyer this 1.05 carat intense yellow sapphire represents a compelling combination of attributes. The size is large enough to command presence in a solitaire ring, a halo setting designed to emphasize color, or as a striking center for a bespoke pendant. The intense natural yellow, augmented by heat treatment, is less common than more familiar blue or pink sapphires, and that rarity contributes to long term desirability among collectors and connoisseurs. The mixed brilliant cut maximizes face up brightness while conserving carat weight, and the excellent polish and balanced proportions demonstrate high quality workmanship. Practical considerations for ownership include classic care, such as routine cleaning with warm soapy water and a soft brush, and avoiding exposure to harsh chemicals or extreme heat that are not relevant to normal wear. If you are considering investing in a distinctive colored sapphire with transparent provenance and thoughtful cutting, The Natural Sapphire Company stands behind this gem with our expertise and service, and we can assist with certification, custom settings, and long term care guidance to ensure this yellow sapphire becomes a treasured part of your collection.
