0.68 Ct. Yellowish Green Sapphire from Madagascar

This transparent 0.68 carat round yellowish green sapphire from Madagascar, offered by The Natural Sapphire Company, presents a precise balance of size and optical performance that makes it ideal for custom jewelry. The gem measures 5.05 x 5.07 x 3.54 mm, dimensions that indicate near perfect round symmetry for easy, predictable setting in traditional four or six prong mounts, modern bezel settings, or as a calibrated center for halo and three stone designs. The mixed brilliant cut combines a brilliant faceted crown with a modified pavilion, producing a controlled interplay of fire and scintillation while maintaining strong face up color saturation. With medium intense color intensity, the stone reads rich yet versatile in face up presentation, and the yellowish green hue translates beautifully under both warm and cool white light sources. Evaluated at eye level, clarity is very very slightly included, which means the stone reads clean to the naked eye and retains excellent light return and contrast without distracting inclusions.

From a craftsmanship standpoint the sapphire exhibits excellent polish and careful facet junctions, attributes that optimize contrast and scintillation, and that simplify predictable interaction with metalwork during mounting. The nearly equal girdle measurements confirm symmetry that bench jewelers value when planning bezel walls, collets, or tension fittings, and the modest depth of 3.54 mm supports a strong balance between face up diameter and pavilion depth, preserving color saturation while maximizing apparent size. Heat treatment has been applied, a stable and industry standard enhancement that improves color uniformity without compromising durability. For designers and experienced clients seeking a focal stone for custom engagement rings, bespoke pendants, or a matched pair of stud settings, this sapphire offers reliable setting behavior, durable hardness suitable for daily wear, and the visual complexity that mixed brilliant faceting provides. The Madagascar origin contributes known material characteristics that often include lively color and fine crystal clarity, making this gem a technically compelling choice for refined custom work.
