1.08 Ct. Ruby from Tanzania

This 1.08 carat cushion shape ruby from Tanzania is a transparent natural gem presented by The Natural Ruby Company. The stone measures 6.23 by 5.65 by 3.09 millimeters and is fashioned in a mixed brilliant cut that balances broad, velvety color planes with lively facet scintillation. Clarity is graded slightly included at eye level, and the gem displays a vivid color intensity combined with an excellent polish. There has been no enhancement, and the combination of natural origin and careful cutting produces a stone that reads as pure and authentic. The cushion outline provides a classic silhouette suited to solitaire rings and refined pendant settings, while the mixed brilliant faceting strategy optimizes return of light and preserves the depth of tone that characterizes fine rubies from Tanzania.

Under natural daylight the ruby exhibits strong saturation and a deep vivid red that reads slightly cool to neutral, with broad flashes from the pavilion and crown facets that reveal internal color zoning only on close inspection. In direct sunlight the stone brightens to reveal crisp red flashes and increased scintillation from the mixed brilliant facets, creating contrast between the deeper core color and lively facet reflections. Under warm incandescent light and traditional candle light the tone shifts subtly toward a warmer, richer red, enhancing the perception of depth and giving the gem a velvety richness. Under modern white LED illumination the stone maintains its vivid intensity while showing clean, sharp facet reflections and moderate dispersion. Slight inclusions do not detract from the visual performance at typical viewing distances, and they can act to break and refract light internally, adding character to the stone without compromising brilliance. The excellent polish ensures smooth facet junctions and uninterrupted light flow, so the ruby offers dependable performance across lighting environments, while its natural, untreated state provides enduring value and provenance for discerning jewelry designs.
