To understand why this ruby sparkles with an intensity that outshines many others, it helps to consider its internal structure and how light interacts with corundum. Ruby is a variety of corundum, whose crystal lattice is compact and strong, allowing it to refract and reflect light efficiently. The presence of chromium atoms in the lattice not only produces the vivid red hue but also contributes subtly to how the stone absorbs and transmits light, creating that deep, lively saturation that appears to come from within. Corundum has a high refractive index, which means that when light enters the stone it bends and slows more than it would in many other gem materials. This bending of light, combined with precise facet placement in a mixed brilliant cut, forces light to travel across multiple internal surfaces before exiting, producing intense light return and pinpoint flashes of brightness that we call scintillation. The mixed brilliant cut used on this cushion shape balances a broad, luminous table with a nuanced crown and a pavilion that encourages internal reflection, so the ruby does not merely appear red, it appears to glow from the inside out.

Beyond the chemistry and optics, the physical execution of the cut and polish sets this stone apart. The cushion shape of 6.60 x 6.58 x 3.56 mm offers a slightly softened silhouette that enhances color concentration in the center while the rounded corners provide a classic elegance that sits beautifully in a variety of settings. The mixed brilliant cut brings together smaller, well aligned crown facets with a precision pavilion that returns light in broad flashes as well as sharp, faceted fire on movement. This combination creates a play of light that is rich and layered, producing both a deep saturated core color and lively surface scintillation that catches the eye from every angle. The excellent polish ensures that facets meet crisply and surfaces are free from polish haze, allowing maximum light entry and exit. Because the ruby is eye clean evaluated at eye level, there are no visible inclusions to interrupt the path of light, so every ray contributes to the gem brightness rather than being absorbed by internal features.
