5.32 Ct. Ruby from Mozambique

This ruby presents as a transparent, oval shape weighing 5.32 carats, with precise measurements of 13.31 by 8.58 by 4.68 millimeters, a mixed brilliant cut, and an excellent polish. The hue is pinkish red with vivid color intensity, and the stone has been heat treated, a common and stable enhancement that improves color uniformity and clarity. Clarity is graded as included when evaluated at eye level, indicating natural internal characteristics that are visible under direct inspection but do not significantly detract from the gem s overall presence. Origin is Mozambique, a source known for producing rubies with rich tones and desirable crystal quality. The Natural Ruby Company stands behind the accuracy of these specifications, and the provided information reflects careful gemological assessment intended to inform mounting and design decisions.

Under natural daylight, particularly indirect north light or diffuse sunlight, this ruby displays its truest pinkish red, with the vivid saturation appearing even across the table and crown facets. The mixed brilliant cut balances large facets and smaller pavilion facets to optimize light return, so in daylight the stone exhibits strong color saturation combined with crisp flashes of white brilliance. Under cool white LED lighting, the ruby s red remains vivid while the white scintillation from the brilliant facets becomes more pronounced, giving a lively, modern sparkle that emphasizes facet contrast. Under warm incandescent or halogen lighting, the ruby shifts toward a warmer, slightly more orangey red that can feel richer and more luxurious, while the interior reflections take on a glowing depth that enhances perceived size and presence. In low light or candlelit environments, the stone retains its vivid tone, though overall brightness diminishes; the mixed brilliant cut continues to produce pinpoint flashes of light, and the excellent polish ensures those flashes are clean and reflective rather than diffuse. The transparency and facet arrangement also allow the viewer to perceive internal depth and subtle color zoning, which contributes to a complex visual character under changing light sources.

The included clarity grade reflects natural inclusions that are characteristic of rubies from primary gem deposits, and these internal features interact with light in ways that can be visually appealing. Inclusions can act as internal reflectors, creating additional scintillation when the stone is viewed from different angles, while also imparting a sense of authenticity and origin. The excellent polish on the pavilion and crown facets maximizes light transmission and minimizes surface diffusion, so the ruby presents a lively and clean face up appearance despite internally visible features. The mixed brilliant cut was chosen to enhance both color saturation and light performance for an oval format that is comfortable for a variety of jewelry settings. When set in an open backed or minimally obstructive mount, the gem will have increased light access from the pavilion, resulting in stronger return and brightness. A bezel or closed back setting will emphasize the stone s color and create a more solid, saturated look, particularly under warm lighting. For daily wear, the stone s dimensions and cut make it suitable for rings, pendants, or bespoke pieces where the design accounts for the included characteristics and the heat treatment enhancement.

Care and handling recommendations are practical and straightforward to preserve the ruby s appearance. Clean with mild soap and warm water using a soft brush, rinse thoroughly, and dry with a lint free cloth, avoiding harsh chemicals and prolonged exposure to extreme heat. Professional inspection and cleaning at regular intervals will help maintain the mount and polish, and will allow assessment of the setting to ensure inclusions do not compromise structural integrity during wear. The Natural Ruby Company provides full disclosure on origin, enhancement, and measured attributes, and can assist with additional information on certification and suitable settings that make the most of this ruby s optical strengths. This 5.32 carat Mozambican ruby is a balance of vivid color, considered cut, and authentic inclusion characteristics, offering predictable and attractive behavior across a range of lighting conditions.
