3.98 Ct. Green Sapphire from Madagascar

When you are searching for a single stone that ends the hunt for depth of color, clarity, and proportion, this transparent 3.98 carat oval green sapphire answers the call. Its 10.16 by 8.14 by 5.42 mm dimensions make it an ideal size for a centerpiece ring, a statement pendant, or a museum quality collection, and its mixed brilliant cut is designed to maximize both face up presence and internal life. Evaluated as eye clean at normal viewing distance, and with an excellent polish, this gem presents vivid color intensity in every lighting condition, and the enhancement by heat treatment is a standard, stable process that refines and unlocks the innate beauty of Madagascar sapphires. If you want a gem that feels complete from first glance, and that will continue to reward close inspection, this stone delivers the balance of technical quality and natural character most customers are seeking.

What sets this green sapphire apart in its category is the way it handles light. The mixed brilliant cut means the pavilion facets work in concert with the crown facets to produce dynamic internal reflections, crisp scintillation, and a pleasing combination of broad flashes and pinpoint sparkle. Compared to typical step cuts, which emphasize depth of color and create more glassy reflections, the mixed brilliant style here returns more lively, multidirectional light, making the vivid green appear to glow from within. The excellent polish on each facet enhances light return, so movement and changing light produce quick, lively reflections rather than dull or muddled shine. Against other sapphires in this color family, this piece tends to present a more spontaneous brilliance, and where many green sapphires emphasize a flat, velvety surface color, this oval offers both saturated hue and animated reflections that attract and hold the eye.

When you compare its reflective qualities to other gemstones in the broader green category, the differences become very telling. Emeralds, prized for their rich green, typically display a softer, oilier luster because of their inclusions and the way light diffuses through them, so they rarely offer the same level of crisp internal sparkle. Tourmalines and tsavorites often deliver bright color with lively surface luster, but many lack the same combination of durability and refractive lift that sapphire provides, so their reflections can appear more domestic and less jewel like. This green sapphire is more brilliant than most emeralds, and it maintains more sustained face up fire and scintillation than many green tourmalines because corundum has excellent refractive properties and in this instance the cut and polish exploit those properties thoroughly. Compared to blue sapphires, which can sometimes read darker due to strong saturation, this Madagascar green sapphire balances darkness and brightness, showing lively green flashes against deeper tones, and it can outperform similarly weighted stones in sheer visual animation when set to catch light.

For an engagement ring, a bespoke piece, or a collector seeking a rare and satisfying stone, this 3.98 carat Madagascar green sapphire is a consummate solution. Its vivid color intensity means it will hold visual presence beside diamonds and other accent stones, its eye clean clarity provides confidence when viewed up close, and the mixed brilliant cut promises show stopping reflections whether you prefer a modern halo, a classic solitaire, or a custom vintage setting. At The Natural Sapphire Company we understand that provenance, craftsmanship, and long term satisfaction matter, and this stone embodies those priorities through its origin, treatment, and finishing. If you want a green sapphire that reconciles the desire for saturated color, lively reflection, and practical durability, this gem will likely be the one that ends the search, and our team can help you decide on a setting that maximizes its reflective strengths while protecting its beauty for a lifetime.
