0.53 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This loose sapphire is a transparent, round shape blue sapphire weighing 0.53 carat, with precise dimensions of 4.66 x 4.65 x 3.22 mm, faceted with a mixed brilliant cut designed to balance table brilliance and pavilion depth, clarity evaluated as very slightly included at eye level, medium color intensity with a clean blue hue, and an excellent polish that accentuates the stone s internal reflections, enhancement is by controlled heat treatment, and origin is Ceylon Sri Lanka. The mixed brilliant faceting pattern produces crisp light return and scintillation across the crown, while the near ideal round outline and carefully proportioned depth provide visual stability in both ring and pendant settings, the stone s transparency and modest eye level inclusions allow the medium blue to present with clarity and evenness, and the excellent polish ensures smooth facet junctions and consistent luster under both natural and artificial light.

At this size, quality Ceylon blue sapphires with medium intensity and notable transparency are comparatively uncommon, this 0.53 carat example occupies a rare position within the market because most stones under one carat from similar origins tend to trade at either paler tones or with more apparent inclusions, the combination of a clean visual appearance at eye level, a well saturated medium blue, and an expertly executed mixed brilliant cut makes this gem less frequently encountered among small round sapphires. The Natural Sapphire Company presents this stone as a technical specimen suitable for refined, minimalist jewellery where color fidelity and optical performance are priorities, the gem is well suited to a solitaire or halo design that preserves table exposure and maximizes perceived size, and the disclosed heat treatment is a stable, industry standard enhancement that improves color uniformity while maintaining structural integrity. For specialists seeking an accurately graded, Ceylon origin blue sapphire with balanced color, high polish, and discreet inclusions at a sub carat weight, this stone represents a distinct and verifiable option.
