0.47 Ct. Yellowish Green Sapphire from Madagascar

This transparent 0.47 carat round yellowish green sapphire measures 4.69 x 4.60 x 3.07 mm, and presents a precise mixed brilliant cut that balances a faceted pavilion with a brilliant crown to optimize return of light. The stone is graded as very slightly included when evaluated at eye level, indicating that inclusions are minor and do not materially interrupt the visual field. The color intensity is described as light, yielding a fresh and delicate yellow green hue that reads as elegant and understated in most lighting conditions. The surface finish is an excellent polish, and the piece has been heat treated, a stable enhancement that is standard across sapphires to improve tone and clarity. The sapphire is sourced from Madagascar, a locality noted for producing a range of attractive sapphire colors, and the offering is presented by The Natural Sapphire Company with full attention to accurate description and care.

In terms of brilliance and optical character this yellowish green sapphire performs with clarity and liveliness that distinguish it from many more common green gemstones. Sapphire has a refractive index in the high range for corundum, which is greater than that of beryl family stones such as emerald and aquamarine, and also exceeds the refractive indices of peridot and most tourmalines. The practical result is a stronger return of light and a firmer sense of sparkle when compared to those stones, producing more apparent brightness in similar lighting. Sapphire dispersion is lower than that of diamond, so the stone exhibits more restrained fire and a crisper flash rather than broad multicolored fire, and the mixed brilliant cut of this round shape amplifies that crisp scintillation by aligning facet angles for efficient light return. The light color intensity and very slightly included clarity further enhance perceived brilliance, because a cleaner pavilion and crown allow light to travel with fewer interruptions, and the yellowish green tone introduces a soft contrast between light and shadow that is visually appealing without overwhelming the gem with saturation.

For practical use in jewelry this 0.47 carat round sapphire offers notable advantages, both aesthetic and functional. Corundum hardness provides strong resistance to scratching, making the gem suitable for daily wear, and the excellent polish preserves a gleaming surface that will continue to reflect light across time. Settings that lift the stone slightly, such as classic prong mounts, will maximize exposure to light and accentuate the mixed brilliant cut, while halo settings can add perceived size and complement the light color without obscuring the stone s distinct tone. For metal choices yellow gold subtly harmonizes with the yellowish green cast, while white gold or platinum offers a modern contrast that emphasizes the stone s clarity and scintillation. Heat treatment is stable and widely accepted in the trade, and the Madagascar origin is consistent with the balanced color and clarity observed in this sample. The Natural Sapphire Company provides complete information on origin and treatment, and stands behind the accuracy of this description for customers seeking a finely cut, durable, and visually lively yellowish green sapphire.
