18.62 Ct. Ruby from Mozambique

Presenting a remarkable transparent 18.62 carat cushion shape purplish red ruby measuring 22.65 x 14.92 x 4.86 mm, offered by The Natural Ruby Company. This individual gem displays a vivid color intensity that sits in the desirable spectrum between classic pigeon blood and deep purplish red, providing saturated hue without appearing overly dark. The clarity is graded included when evaluated at eye level, which is typical for natural rubies of this size and origin, and the stone exhibits an excellent polish that enhances surface luster and tactile finish. Originating from Mozambique, a modern source known for producing large, richly colored corundum, this ruby has been heat treated, a standard and widely accepted enhancement that improves color uniformity and reduces silk without altering the natural crystal structure. For an educated buyer, these attributes combine to offer a transparent, sizeable specimen with natural zoning and characteristic inclusions that confirm its natural origin and provenance, while the vivid color and strong saturation make it a particularly attractive choice for high end jewelry and collectors seeking a balance of beauty and authenticity.

The cushion shape with a mixed brilliant cut plays a central role in maximizing the optical performance of this ruby. The mixed brilliant cut combines larger step facets on the pavilion with a brilliant faceted crown, and in this example the cutter has retained weight while promoting internal reflection and lively scintillation. Crown facets disperse incoming light into vivid flashes, while pavilion steps guide light back through the table for depth and color saturation, creating a balance between brilliance and richness of tone. Because the stone has excellent polish, light transmission is unobstructed, allowing the vivid purplish red color to read consistently in varied lighting conditions, from daylight to incandescent sources. At 18.62 carats and with the dimensions provided, this gem presents a substantial table and a pavilion depth that together enhance attractivity in a center stone setting, delivering presence, fire, and color intensity. The Natural Ruby Company recommends settings that allow light to enter from the sides and crown to fully exploit the mixed brilliant cut, ensuring the stone maintains strong visual impact, and for collectors this specimen represents a combination of notable size, Mozambique origin, and expertly executed cutting that justifies its appeal and value.
