0.21 Ct. Yellow Sapphire from Madagascar

This transparent 0.21 carat round yellow sapphire from Madagascar is a refined example of careful cutting and classic gemological character. The stone measures 3.54 by 3.52 by 1.89 millimeters, and it is fashioned in a mixed brilliant cut that combines a brilliant crown with a faceted pavilion, a combination that maximizes both sparkle and color delivery in a small round form. Clarity is graded as slightly included when evaluated at eye level, which means the gem displays natural internal characteristics that are visible under close inspection but do not significantly detract from overall transparency or light performance. Color intensity is described as medium light, producing a warm, sunny yellow that remains delicate and wearable, and the polish is excellent, lending crisp facet junctions and clean reflective surfaces. The sapphire has undergone standard heat treatment to improve hue and clarity, a stable and widely accepted enhancement in the trade, and provenance from Madagascar adds interest, because Madagascar has produced attractive yellow sapphires with consistent tone and good crystal quality.

Optical performance of this gem varies pleasingly with ambient light, and understanding that behavior helps an educated buyer anticipate how it will perform in everyday wear and in photographic settings. In bright daylight with a neutral color temperature the mixed brilliant cutting scheme returns lively white flashes from the crown facets, while the medium light yellow body color reads as fresh and luminous rather than overly saturated, creating a bright but refined appearance. Under strong direct sunlight the stone will show increased scintillation and pronounced contrast between the white brilliance and the golden body color, giving a cheerful and eye catching presence. Under warm incandescent or candlelight the yellow warmth deepens slightly, moving toward a richer golden tone that emphasizes the gemological warmth imparted by iron related chromophores, and under cool white LED lighting the stone retains clarity and sparkle, though the perceived color may shift subtly toward paler yellow. Because the pavilion depth is modest given the millimeter profile, light leakage is minimized and light return remains efficient, so the gem performs well in both open settings and lower profile mounts.

For an educated buyer this Madagascar yellow sapphire represents a thoughtful balance of natural origin, technical finish, and realistic expectations about enhancement and clarity. Slightly included clarity in a 0.21 carat stone typically reflects untreated crystal formation or healed fractures, and when combined with excellent polish and a well executed mixed brilliant cut the result is a gem that appears lively and clean to the unaided eye while retaining character under magnification. Heat treatment is noted and accepted as a stable process that improves optical qualities without compromising durability, which is important for clients seeking longevity and day to day wearability. The measured dimensions make this an ideal accent or minimalist center stone for fine jewelry where color and precision matter, and its Madagascan origin adds a provenance narrative that collectors and conscientious buyers appreciate.
