14.59 Ct. Topaz from Ceylon (Sri Lanka)

One beautiful transparent 14.59 carat oval blue topaz, measuring 18.00 by 13.03 by 8.72 millimeters, presents a rare combination of size and eye appeal that will interest the informed buyer. The gem is fashioned with a mixed brilliant cut, and it displays a clarity grade described as very very slightly included when evaluated at eye level, which effectively means the stone reads as eye clean under normal viewing and transmits light with minimal obstruction. The color intensity is medium light, a tone that balances vibrancy with elegance, and the polish is graded excellent, giving crisp facet junctions and high surface reflectivity. Origin Ceylon, Sri Lanka, is noted for producing clean, well crystallized topaz material, and this specimen has undergone irradiation enhancement to achieve and stabilize its appealing blue hue. Documentation of this standard treatment is provided, and the color produced by professional irradiation is considered stable under normal wearing conditions, although routine care avoiding extreme heat and harsh chemicals is recommended.

From a cutting and light performance perspective, the mixed brilliant cut on this oval topaz is engineered to maximize both brilliance and scintillation. The cutter has combined a brilliant style pavilion with a carefully proportioned crown to create strong internal light return and lively flashes as the stone moves. With an average of the length and width at approximately fifteen point five millimeters, the depth of eight point seven two millimeters yields a depth ratio of approximately fifty six percent, a proportion that contributes to balanced light performance rather than a washed out or overly deep appearance. The oval outline increases the face up appearance relative to weight, and the facet layout concentrates reflected light toward the table and crown, enhancing perceived brightness and color saturation without sacrificing transparency. For buyers who value technical execution, this stone represents a convergence of material quality and precise cutting, and The Natural Gemstone Company stands behind the gemology and provenance provided. This topaz is especially well suited to high end rings or pendants where its size, eye cleanliness, refined cut, and Ceylon origin can be appreciated in direct light, and it offers long term value for collectors seeking a substantial, well finished blue topaz.
