0.50 Ct. Yellowish Green Sapphire from Madagascar

This listing presents one beautiful transparent 0.50 carat fancy shape yellowish green sapphire, with precise dimensions of 4.40 by 4.27 by 3.22 mm, and a mixed brilliant cut designed to maximize scintillation and light return. The gem exhibits intense color intensity and an excellent polish, and it carries a clarity grade of very very slightly included, evaluated at eye level, reflecting inclusions that are minute and do not affect face up appearance. This sapphire is natural and untreated, confirmed as no enhancement, and its documented origin is Madagascar. At The Natural Sapphire Company we describe each stone with technical accuracy, so an educated buyer can understand the combination of cut, clarity, color, and origin that defines the gem value. The fancy shape presents an elegant alternative to classic rounds, and the mixed brilliant pavilion optimizes both fire and brightness while preserving carat weight in a pleasing optical package.

From a grading perspective this sapphire scores strongly across the four classic parameters that informed buyers use to evaluate gems. Carat weight of 0.50 places this stone in a size range that is versatile for fine jewelry, and the actual millimeter measurements indicate a well proportioned profile for precision setting. The mixed brilliant cut combines a faceted crown and a pavilion geometry that is tailored to corundum, producing crisp facet junctions and lively return of light. Clarity at very very slightly included, evaluated at eye level, indicates that observable inclusions are minimal under normal viewing conditions, and the stone reads as clean and transparent to the unaided eye. The excellent polish guarantees that facet planes are smooth and reflective, which enhances brightness and allows the intense color to be seen without obstruction. Because there has been no enhancement, the color and clarity represent the stone in its natural state, a factor that adds both aesthetic and investment appeal for discerning collectors.

Color is the principal attribute that defines the personality and market desirability of this sapphire, and the yellowish green hue with intense saturation is an especially attractive and collectible tone. In corundum, green and yellow tones often arise principally from iron and related trace elements, and in this specimen the balance of hue and saturation produces a lively color that interacts beautifully with both warm and cool metal settings. The intensity of color is strong enough to be distinctly present when set in jewelry, yet the tone remains light enough to allow remarkable clarity and brilliance to come through. A mixed brilliant cut further enhances color distribution by creating multiple clean facet planes that both reflect and refract light internally. For buyers who appreciate color nuance, this stone shows subtle shifts when viewed from different angles, adding depth and complexity without appearing muddy or overly dark. The untreated nature of the gem means that its color is original to the stone, a quality that educated buyers prize because it preserves natural character and often holds value better over time.

The documented origin of Madagascar contributes significantly to the value proposition of this sapphire, because origin is a legitimate and verifiable factor that informed collectors and investors use to assess provenance and geological pedigree. Madagascar is a relatively young, yet highly important, source of fine sapphire that has produced a broad range of colors and high quality material in recent decades. The island is known for diverse geological environments that can yield distinct crystal chemistry, and stones from Madagascar often display a combination of clarity, vibrant hue, and interesting color range that distinguishes them on the market. For buyers focused on traceability and ethical sourcing, Madagascar is also notable because many reputable dealers and laboratories now provide clear origin reports and supply chain transparency for stones from this region. At The Natural Sapphire Company we emphasize origin because it is an objective attribute that complements cut, color, clarity, and carat when determining desirability and fair market value. Additionally, the durability of corundum, whose hardness is nine on the Mohs scale, makes this natural, untreated Madagascar sapphire an excellent choice for daily wear in rings and other jewelry, while its unusual yellowish green color lends itself to bespoke designs and collector grade pieces.
