0.89 Ct. Ruby from Mozambique

This transparent 0.89 carat asscher octagon shape red ruby measures 5.50 x 5.20 x 3.07 mm, it is faceted with an asscher cut, it is graded eye clean when evaluated at eye level, it displays vivid color intensity, and it has an excellent polish. This ruby is entirely natural, with no enhancement, and it originates from Mozambique, a source known for producing saturated and market desirable rubies. The combination of precise asscher faceting, consistent transparency, and strong color saturation makes this stone particularly appealing to educated buyers who value provenance, untreated material, and technical quality. The Natural Ruby Company stands behind the origin and treatment status, and we present this gem with full confidence in its gemological attributes.

The exceptional sparkle of this ruby derives from its internal structure as corundum and from the geometry of its asscher faceting. Ruby as a species has a refractive index near 1.76, which means it bends and concentrates light more strongly than many common gem materials, creating pronounced internal reflections. The asscher cut, with its stepped crown and pavilion facets arranged in a square octagon profile, produces a hall of mirrors effect, showing parallel flashes and depth rather than mere scattered scintillation. Because this example is eye clean, light traverses the crystal with minimal obstruction, allowing the stepped facets to return uninterrupted flashes of saturated red and bright highlights. The excellent polish further reduces surface scattering, so each facet edge acts as a precise mirror, intensifying contrast between deep red flashes and bright reflective planes.

For the connoisseur or collector, this ruby offers a rare convergence of traits that drive both aesthetic and investment value, natural untreated origin, vivid hue, eye clean clarity, exacting asscher proportions, and expert polish. The asscher cut here emphasizes color and clarity while delivering a distinctive optical signature, one that is immediately recognizable and prized among gem enthusiasts. If you seek a ruby that combines classic step cut elegance with the intense, living color of a Mozambique stone, this 0.89 carat asscher octagon ruby from The Natural Ruby Company represents a compelling choice ready to be set in a refined jewelry design or retained as a standalone collector piece.
