0.56 Ct. Bluish Green Sapphire from Madagascar

This transparent 0.56 carat oval shape bluish green sapphire is presented by The Natural Sapphire Company with complete gemological detail. The stone measures 5.05 x 3.92 x 3.35 mm, and it is fashioned in a mixed brilliant cut that balances table brilliance with pavilion light return. Clarity is graded very slightly included, evaluated at eye level, which indicates minor internal features that do not detract from the overall visual appeal. Color is described as bluish green with medium intensity, providing a balanced presence without overpowering saturation. The sapphire has an excellent polish that enhances surface smoothness and enhances its reflective qualities. The gem is heat treated, a common and widely accepted enhancement that improves color uniformity and clarity, and this treatment is disclosed as part of the stone specification.

Optical and structural characteristics drive the visual performance of this sapphire, and the mixed brilliant cut has been selected to optimize scintillation while maintaining a flattering oval silhouette. The crown and pavilion faceting work together to produce a lively mix of flashes and depth, and the excellent polish maximizes light return and minimizes surface irregularities. The medium intensity bluish green color allows the stone to display nuanced color zoning and pleochroism when viewed from different angles, a trait often seen in sapphires that adds dynamic interest. With a very slightly included clarity grade, the inclusions are minor and typically only detectable under close inspection. These inclusions can in some cases serve as internal fingerprints confirming natural origin, while still permitting the gemstone to present with transparent, gem quality appearance suitable for fine jewelry fabrications.

The origin of this sapphire, Madagascar, contributes materially to its desirability and value. Madagascar has emerged as a significant source of gem quality corundum, producing stones that are known for their varied and often complex colors, resulting from trace element chemistry and local geological conditions. Sapphires from distinct Madagascar deposits frequently exhibit interesting mixed hues, including bluish green tones, due to variable concentrations of iron, titanium, and chromium. Provenance from Madagascar informs collectors and designers about expected color behavior, crystal habit, and treatment likelihood, and it can increase interest among buyers who value documented origin. In addition to geological distinctiveness, sourcing from Madagascar aligns with a contemporary emphasis on traceable supply chains. Buyers attentive to responsible sourcing and transparency often regard well documented origin as an important factor when assessing long term value and desirability, and provenance documentation supplied by The Natural Sapphire Company supports informed decision making.

Heat treatment is the disclosed enhancement applied to this sapphire, and it is a stable, industry standard process that improves color tone and reduces the visibility of some inclusions without compromising durability. Heat treated sapphires remain suitable for everyday wear given corundum hardness, and their structural integrity is preserved under normal jewelry usage. For settings, this stone works well as a centerpiece in rings, pendants, or fine earrings where its oval form and measured dimensions can be balanced by complementary mounting design. Select settings that protect the girdle and edges, and clean the sapphire with warm soapy water and a soft brush for routine care. Ultrasound cleaning is generally acceptable for heat treated corundum, but avoid steam or chemical exposure when the treatment history is uncertain. The Natural Sapphire Company provides detailed documentation with each gem, and prospective buyers can review full gemological reports and photographs to confirm specifications and provenance prior to purchase.
