0.55 Ct. Greenish Yellow Sapphire from Montana

This transparent greenish yellow sapphire weighs 0.55 carat and is cut to an elegant oval shape with dimensions of 6.04 by 4.09 by 2.89 millimeters. It is fashioned in a mixed brilliant cut, combining a faceting scheme designed to maximize light return with a silhouette that suits a wide range of settings. The clarity grade is very slightly included, evaluated at eye level, and the stone displays an intense color intensity that produces a rich, even greenish yellow body color. The polish is excellent, and the faceting shows crisp facet junctions and well controlled symmetry, which together enhance both color saturation and light performance. The sapphire has undergone standard heat treatment to stabilize and intensify its hue, and its documented origin is Montana. This combination of material quality, cut, and finish delivers a compact gemstone that reads larger than its weight might suggest, and that maintains strong visual presence when set.

In direct optical comparison to more common gemstones, this Montana sapphire presents a distinct type of brilliance. Unlike diamond, which achieves its signature scintillation through a higher refractive index and dispersion, corundum produces a steadier, more saturated internal glow that is driven in part by its intrinsic color and strong luster. Against yellow or golden varieties of topaz and citrine, this sapphire stands out for its greater durability and for the depth of its color under varied lighting, rather than for overt fire. The mixed brilliant cut has been applied to optimize pavilion angles and crown geometry so that light entering the stone is returned with lively scintillation and clear color flashes, rather than being dispersed as broad spectral fire. The very slight inclusions are not intrusive at eye level and serve in some viewing angles to add character without diminishing brilliance. For a buyer seeking a colored gem with focused, intense color, precise polish, and dependable light performance, this piece offers a refined balance of optical appeal and practical durability, and it is offered through The Natural Sapphire Company.
