0.56 Ct. Greenish Yellow Sapphire from Madagascar

This 0.56 carat greenish yellow sapphire presents as a compact and exceptionally well finished round gem, with exact dimensions of 4.62 by 4.65 by 3.31 millimeters and a mixed brilliant cut that has been executed with care. The mixed brilliant design combines a brilliant style crown with a carefully faceted pavilion to optimize both scintillation and color saturation, and the excellent polish ensures that facet junctions remain sharp and reflective. Clarity is described as very slightly included when evaluated at eye level, which in practical terms means the stone is effectively clean to the unaided eye and maintains full transparency and sparkle. The light color intensity is delicate and pleasing, allowing the greenish yellow hue to read as elegant and versatile. Because the gem is transparent, with inclusions that are minor and unobtrusive, it presents a bright, lively face up appearance and projects its subtle color evenly across the table, rather than concentrating color in isolated areas.

From a gemological perspective the origin of Madagascar contributes to the character and desirability of this sapphire, Madagascar being a well documented source for a diverse range of corundum colors. The subtle greenish yellow tone in this sapphire is consistent with trace concentrations of iron and related chromophore elements that create a pleasing, slightly grassy yellow rather than a strong, saturated canary tone, making the color both unusual and wearable. The sapphire has been heat treated, which is a stable and widely accepted enhancement that improves clarity and refines color without compromising structural integrity, and this treatment is disclosed to ensure transparency for the educated buyer. Optical proportions are notable, with a measured depth of 3.31 millimeters relative to an average diameter of 4.635 millimeters, producing a depth of approximately 71.4 percent. While this depth is deeper than classical ideal proportions for a round brilliant, in a mixed brilliant cut it can contribute additional pavilion facet area, enhancing internal reflections and depth of color, so the gem reads with concentrated brilliance and an appealing three dimensionality when set.

The way this stone appears from every angle reflects both the quality of the material and the precision of the cutting. The excellent polish allows light to enter and exit with minimal scattering, and the mixed brilliant facet arrangement returns light as crisp flashes of white brilliance and subtle spectral dispersion, so the gem appears lively and consistent as it moves. Because the inclusions are very slight and the stone is transparent, the visual presentation is effectively pristine in most viewing conditions, which is why it may be described as virtually flawless to the eye. For an educated buyer looking for both gemological integrity and aesthetic performance, this sapphire offers a compelling balance of rarity and usability. At 0.56 carat the stone is versatile for fine jewelry, particularly in delicate solitaire settings, halo rings that emphasize its light color, or as matched pairs in refined stud earrings. The Natural Sapphire Company stands behind careful disclosure of origin and treatment, and we can provide additional photographic views and independent gemological reporting upon request to support provenance and to assist with design decisions. This Madagascar greenish yellow sapphire is an excellent choice for collectors and designers who value precise cutting, stable treatment, and a subtle but distinct color that performs gracefully in daylight and artificial light alike.
