0.43 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 0.43 carat round shape blue sapphire, measuring 5.08 x 5.05 x 2.30 mm, presents a precise balance of size and presence. The stone is cut in a mixed brilliant style, a facet arrangement that maximizes return of light while retaining a refined pavilion depth. Evaluated at eye level, clarity is graded very slightly included, a condition that preserves visual transparency while adding natural character. The color displays an intense saturation, evenly distributed throughout the stone, and the surface exhibits an excellent polish, producing crisp facet junctions and lively scintillation. Enhancement is by controlled heat treatment, a standard and stable method used to improve hue and clarity, and the gem is sourced from Ceylon, Sri Lanka, a provenance noted for producing vivid, cornflower blue tones and fine crystalline structure. The combination of transparency, cut proportions, and polish creates a gemstone that reads clean and bright at typical viewing distances.

As an object of personal adornment, this sapphire will continue to captivate over the years, owing to its inherent material durability and enduring color stability. Sapphires are among the hardest natural gemstones, and when set with appropriate care in secure mountings, this 0.43 carat gem will retain its polish and brilliance with routine cleaning and occasional professional inspection. The mixed brilliant cut offers versatile styling options, appearing equally elegant in a solitaire ring, halo setting, or as a refined accent stone, and its modest carat weight makes it suitable for daily wear without sacrificing visual impact.
