14.59 Ct. Blue Topaz from Ceylon (Sri Lanka)

One beautiful transparent 14.59 carat oval shape blue topaz from Ceylon, Sri Lanka, is presented with dimensions of 18.00 x 13.03 x 8.72 mm, a mixed brilliant cut, and a clarity grade of very very slightly included, evaluated at eye level, light color intensity, excellent polish, and an irradiated enhancement. The substantial carat weight and clean eye level appearance make this specimen noteworthy for collectors and connoisseurs who prioritize both size and clarity. The mixed brilliant cut on this oval topaz combines a faceted crown designed to break and scatter incoming light with a pavilion architecture optimized to return light through the table, resulting in a balance of brilliance and scintillation suited to the lower dispersion of topaz relative to gemstones like sapphire and diamond. The cut proportions yield a depth ratio of approximately fifty six percent based on the noted dimensions, a figure that supports strong light return without sacrificing face up spread, and the excellent polish ensures minimal surface diffusion so that the stone presents crisp facet junctions and lively contrast under varied lighting.

For the educated buyer, several technical attributes define the value proposition of this stone as offered by The Natural Gemstone Company. The very very slightly included clarity grade indicates that inclusions are minimal and do not materially interrupt internal light paths, preserving the intensity of the mixed brilliant design and enhancing the perceived transparency. The light blue hue achieved by controlled irradiation is uniform and stable, a widely accepted enhancement in the trade when fully disclosed, and it produces an attractive, marketable color in a size that is uncommon for topaz of this quality. Origin from Ceylon, Sri Lanka, contributes provenance value, given the island s long history of producing fine gem material and careful lapidary work. Taken together, the combination of substantial carat weight, thoughtful mixed brilliant cutting, excellent polish, transparent clarity, disclosed irradiation, and Ceylon origin positions this blue topaz as a high value option for fine jewelry settings and private collections, delivering both visual performance and documented technical merit.
