8.25 Ct. Ruby from Mozambique

This is a transparent 8.25 carat cushion shape ruby that combines impressive size with precise cutting, offered by The Natural Ruby Company, it measures 16.10 by 10.60 by 4.80 mm, and its mixed brilliant cut has been executed to maximize face up color and scintillation. The stone presents a vivid color intensity, a saturation that reads as true rich red under standard daylight, and an excellent polish that delivers crisp facet outlines and lively light return. Clarity has been evaluated as slightly included at eye level, which for a ruby of this scale is consistent with natural formation and can add character without significantly diminishing brilliance when set and viewed from a normal wearing distance. This ruby has been heat treated, a widely accepted and stable enhancement in the trade that improves transparency and color uniformity while remaining durable and easy to care for under ordinary wearing conditions.

For an educated buyer this ruby is attractive on several technical and provenance fronts, the 8.25 carat weight places it in a size category where color and clarity are noticeably more impactful to appearance and value than in smaller stones, and the cushion shape is a classical pavilion design that yields generous surface area for the vivid red color to display. The mixed brilliant cut combines step and brilliant faceting to balance depth of color with lively return of light, a choice that conserves carat weight while enhancing apparent richness. Slight eye level inclusions are typical of natural rubies, and because they do not reach a level that impairs transparency, the stone retains a clean appearance when mounted. Origin from Mozambique adds further context to its value profile, because Mozambique is recognised for producing rubies with strong, saturated red hues and relatively modern supply chains, collectors and connoisseurs often prize stones from this locality for the combination of color and economic rarity. Heat treatment is disclosed, and it should be understood that this is a stable, long accepted enhancement that improves optical properties without compromising structural integrity, this is important to buyers who want transparent documentation of any treatments and prefer stones that will age gracefully.

The long term appeal of this ruby is grounded in both its intrinsic material properties and the practical realities of wear, with a hardness of 9 on the Mohs scale and excellent polish the stone resists surface wear and preserves its faceting, the vivid color will continue to captivate because the chromophore chemistry that produces the red does not fade with exposure to normal light, and the stability of heat treatment underpins the enduring uniformity of color and transparency. Over years of wear or periodic display the gem will maintain its visual impact, and should minor surface abrasions occur a skilled lapidary can repolish facets to restore full brilliance without significant loss of carat weight. For setting, recommend protective styles that secure the girdle and minimize exposure of the pavilion to knocks, a bezel or secure prong setting with a moderate profile will protect the stone while allowing maximum face up color to show, and choosing warm white metals will complement the ruby hue.
