3.31 Ct. Ruby from Mozambique

This transparent red ruby weighs 3.31 carat and presents a classical cushion shape with dimensions of 9.63 x 7.84 x 4.96 mm, rendered in a skilled mixed brilliant cut. The stone displays vivid color intensity and an excellent polish that enhances its face up presence and light return. Clarity is graded as very slightly included when evaluated at eye level, indicating small internal features that do not detract from overall transparency. The ruby has been heat treated to improve color uniformity and clarity, and its provenance is Mozambique, a source known for producing richly colored corundum. The Natural Ruby Company offers this gem as an example of careful selection and cutting, suited to a wide range of fine jewelry settings where a balance of size, color, and durability is required.

The narrative of this ruby begins millions of years ago deep within the Earth during episodes of regional metamorphism and tectonic activity in what is now Mozambique. Under conditions of elevated temperature and pressure, aluminum rich protoliths recrystallized to form corundum, the mineral species that comprises ruby, while trace chromium became incorporated into the crystal lattice and produced the characteristic red hue. Over geologic time the host rocks were uplifted, fractured, and subjected to weathering and erosion, processes that freed resilient ruby crystals from their matrix and concentrated them in secondary deposits. Human hands then recovered rough material, and lapidary skill transformed the natural crystal into a precisely faceted gem. Heat treatment applied by experienced technicians optimizes the stone by reducing internal absorption and honing its vivid color, while the mixed brilliant cut and excellent polish maximize brilliance and visual appeal. The Natural Ruby Company documents the gemology and origin of this ruby, and presents it as a specimen that reflects both Earths complex formation history and contemporary craftsmanship in gem cutting and finishing.
