1.21 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent round yellow sapphire weighs 1.21 carats, with precise physical dimensions of 6.41 by 6.40 by 4.03 millimeters, and it is presented by The Natural Sapphire Company. The gem exhibits an intense yellow color intensity, a clarity grading recorded as very very slightly included when evaluated at eye level, and an excellent polish. The cutting style is a mixed brilliant cut, and the sapphire is unenhanced, originating from Ceylon Sri Lanka. These baseline specifications establish a gem that is both technically refined and visually compelling, combining desirable weight and diameter proportions with a natural, untreated saturation that speaks to high quality material and careful selection during sourcing.

The geometry of the mixed brilliant faceting has been executed to maximize optical performance, and the relationship between crown, table, girdle, and pavilion generates an exceptional light return and dynamic scintillation. The proportions yield an overall depth of approximately 63 percent, a balance that optimizes the path of incident light for both return and dispersion without sacrificing face up spread. Above the girdle the brilliant style crown facets and carefully proportioned table create a mosaic of small mirror planes that break light into lively flashes, while below the girdle the mixed approach uses stepped lower facets to lengthen optical paths and reinforce internal reflection. The result is a controlled interplay between pinpoint scintillation and broad area flash, a characteristic advantage of a well executed mixed brilliant design in a round outline. Precise symmetry and facet alignment minimize leakage and produce even, predictable return across the table and crown, and the excellent polish enhances facet crispness so that faceting junctions read with clarity under loupe magnification and with the naked eye.

Craftsmanship considerations extend beyond the faceting geometry to material selection and finishing decisions that influence performance in wearable settings. The eye level clarity assessment of very very slightly included indicates minimal visual disturbance from inclusions, allowing the intense color to read cleanly and the faceting pattern to operate without shadowing from internal features. Because the sapphire is unheated, the color chemistry and crystal lattice have not been altered by thermal enhancement, which preserves natural zoning characteristics and ensures color response under varied lighting conditions. For settings that prioritize maximum light play, an open prong or cathedral mount will permit unobstructed light entry to the crown and escape through the pavilion, maintaining the lively scintillation and brilliance engineered into the cut. For durability and a more modern aesthetic, a low bezel can protect the girdle while still allowing the mixed brilliant geometry to perform effectively, especially when the bezel is designed to minimize metal coverage over the crown. At The Natural Sapphire Company we evaluate each stone for optimal pairing with metal work and setting architecture, and this 1.21 carat Ceylon yellow sapphire is well suited for engagement rings, single stone pendants, or as a highlighted accent in multi stone compositions, due to its balanced proportions, intense color saturation, and superior finish, please contact us for additional measurements, light performance imagery, or bespoke setting recommendations tailored to preserve the maximum optical potential of this natural, unenhanced Ceylon sapphire.
