0.41 Ct. Yellowish Green Sapphire from Madagascar

This transparent 0.41 carat round yellowish green sapphire from Madagascar presents a compact yet technically refined offering for precision jewelry design, with exact dimensions of 4.33 x 4.34 x 2.94 millimeters. The gem has been cut to a mixed brilliant specification, combining a brilliant style crown with a carefully faceted pavilion, and it displays a light color intensity that reads as a delicate yellow green in most lighting environments. Clarity is graded as very very slightly included when evaluated at eye level, indicating only minute internal features that do not detract from overall visual performance. The polish is excellent, ensuring crisp facet junctions and minimal surface disturbance to light return. The stone has undergone standard heat treatment to enhance hue and clarity, a stable and widely accepted enhancement for corundum, and the Madagascar origin contributes to the subtle, slightly cool undertone that defines this particular color balance.

The mixed brilliant cut on this round sapphire has been executed to maximize scintillation and return across a small diameter, with a measured depth that produces an effective depth percentage of approximately 67.8 percent, calculated from the mean diameter and pavilion depth. This slightly deeper profile concentrates color saturation toward the center and produces pronounced contrast patterning under direct light, which benefits small stones intended as focal points in detailed settings. The crown and table facets are proportioned to generate a pleasing balance between fire and brilliance, while the pavilion facet architecture supports controlled light leakage for a lively but not overly bright face up appearance. Subtle pleochroic tendencies between yellow and green may be revealed when the gem is rotated, a desirable characteristic for designers seeking a dynamic color shift in response to movement. The very very slightly included clarity grade means inclusions are minimal at typical viewing distances, allowing the stone to read cleanly in rings and earrings, and the excellent polish minimizes any microabrasion that could otherwise blunt facet edges and reduce optical performance.

This sapphire is exceptionally adaptable for a wide range of custom settings, and The Natural Sapphire Company can advise on mounting choices to maximize both optical effect and security. For a solitaire ring, a low bezel will protect the shallow girdle area while allowing the mixed brilliant crown to display its scintillation, whereas a four or six prong setting elevates the stone to emphasize light entry through the crown and to showcase the slight pleochroism. In halo and cluster designs, the stone size and light color intensity make it an ideal center for a single row of smaller white sapphires or diamonds, where the halo will visually enlarge the face up appearance and enhance perceived color. For a discreet and modern application such as stud earrings or a pendant, a flush or tension setting produces a sleek profile, while channel set bands can incorporate this stone as an accent in a graduated sequence, matching cut and proportions for consistent light behavior. When combining with other gems, coordinate warm yellow sapphires or cool teal stones to either reinforce the yellow green tone or create complementary contrast. Given the depth and facet architecture, we recommend seat designs that respect the 2.94 millimeter pavilion depth to avoid undue pressure on facet junctions during setting, and professional setting techniques will preserve the integrity of the heat treatment and polish.

As The Natural Sapphire Company we offer bespoke consultation to adapt this Madagascar yellowish green sapphire into engagement rings, cocktail pieces, delicate pendant work, or artisan crafted earrings, tailoring bezel thickness, prong profile, and supporting accent stones to the optical signature of the stone. Our bench can recommend metal colors that best harmonize with the light color intensity, with platinum or white gold emphasizing the cooler green notes, and yellow or rose gold enhancing the warmer yellow aspect. We can also source and match companion stones for paired earrings or three stone rings, ensuring consistent cut geometry and visual balance. If you would like a technical mounting diagram, CAD renderings, or a consultation on ideal stone orientation for maximum color shift, The Natural Sapphire Company will provide detailed guidance to realize a finished piece that respects the sapphire s dimensions, cut, clarity, and origin, delivering a custom piece that highlights the gem s nuanced performance and durable character.
