1.61 Ct. Ruby from Mozambique

This 1.61 carat oval ruby from Mozambique presents a precise combination of classic proportions and meticulous cutting, measuring 7.45 x 5.96 x 4.26 mm. The gem is fashioned in a mixed brilliant cut, with a brilliant style crown delivering strong light return and a carefully calibrated pavilion that balances fire and windowing, creating a vivid red face up. Clarity is assessed as very very slightly included at eye level, indicating inclusions are minimal and do not detract from transparency or light performance, and the finish is described as excellent polish, producing crisp facet junctions and bright facet mirrors. The color shows vivid intensity, a saturated pure red with slight modulation in tone across pavilion facets that enhances scintillation, and the stone is transparent and heat treated to optimize color and clarity, a stable enhancement commonly used for Mozambican rubies. The depth to average diameter ratio is approximately 63.5 percent, a proportion that supports strong brilliance while maintaining an elegant oval outline, and the cutting symmetry preserves optical balance for both solitaire and fine jewelry settings. The Natural Ruby Company offers this gem with clear provenance, technical grading notes, and imagery demonstrating scale and hand placement for appraisal of visual presence.

On the Mohs hardness scale this ruby rates at 9, which places it just below diamond and on par with other corundum species such as sapphire, and this high hardness confers excellent resistance to surface scratching and wear for everyday jewelry applications. Hardness alone does not equal toughness, and while rubies are generally durable, internal fissures or included mineral content can influence impact resilience, so a protective mounting such as a bezel or substantial prongs is recommended for ring settings that will receive frequent contact. Heat treatment applied to enhance color is stable under normal wear conditions, but standard care practices are advised, including avoiding harsh chemical cleaners and aggressive ultrasonic cleaning without prior evaluation by a gemological laboratory. For longevity, periodic professional inspection of the mounting is recommended to ensure secure setting, and routine gentle cleaning with mild soap and a soft brush will maintain the excellent polish and vivid color that distinguish this Mozambican oval, available through The Natural Ruby Company.
