4.09 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent 4.09 carat yellow sapphire, cut in a refined emerald shape and measuring 11.12 x 7.60 x 4.88 mm, represents a rare combination of weight, clarity, and origin that will appeal to an educated buyer. The emerald cut emphasizes broad step facets that create a crisp, architectural appearance, allowing the medium color intensity to present as an even, lively yellow across the table. Graded as eye clean at normal viewing distance, this sapphire displays negligible inclusions to the unaided eye, which preserves its visual purity and demand. The excellent polish further enhances the stone, producing clean facet junctions and smooth planes that maximize light travel through the sapphire. Origin Ceylon, Sri Lanka, contributes important provenance, since Ceylon sapphires are historically prized for their pure, appealing hues and often superior clarity. The piece has been heat treated, a widely accepted and stabilizing enhancement in the trade that improves color and clarity without compromising durability or permanence.

The 4.09 carat weight is the defining attribute that elevates this sapphire beyond a common accent stone, because sapphires of this size and eye clean clarity are significantly less abundant than smaller material, and market value typically increases disproportionately as carat weight climbs. For an informed purchaser, a well proportioned 4.09 carat yellow sapphire offers both visual presence and investment merit, as size enables more impactful center stone designs while retaining the wearability afforded by sapphire hardness 9 on the Mohs scale. The emerald cut proportions and the measured depth of 4.88 mm create an attractive table spread, which allows the color to read true without appearing overly deep or washed out. When set as a solitaire or a bespoke design, this sapphire will command attention with a refined, luminous yellow that is unmistakably natural in origin and carefully finished. The Natural Sapphire Company presents this gem for customers seeking a distinguished, wearable, and collectible yellow sapphire with transparent quality, meaningful carat weight, and reliable Ceylon provenance.
