Faceted Ruby – Mozambique
Natural faceted ruby from Mozambique, one of the world's most important modern sources of rubies. Ruby is the red variety of the mineral corundum (Al₂O₃), whose characteristic color is primarily caused by the presence of chromium. Thanks to its exceptional hardness, distinctive color, and durability, ruby is among the most sought-after gemstones used in jewelry.
Origin and Locality
Mozambique became a major ruby producer following the discovery of extensive deposits in the Montepuez area of Cabo Delgado Province in 2009. Rubies are found both in their primary host rocks, particularly amphibolites, and in secondary sedimentary deposits, where they became concentrated through prolonged weathering and erosion.
Appearance and Properties
Mozambican rubies display a wide range of red shades, from pinkish-red and purplish-red to vivid red and darker red tones. Their coloration is influenced by the concentration of chromium, iron, and other trace elements. Natural inclusions, growth structures, and small internal fractures are common, with their abundance affecting the transparency and overall quality of the gemstone.
Ruby has a hardness of 9 on the Mohs scale, making it one of the hardest natural minerals. It is highly resistant to scratching and, when properly set, is suitable for everyday jewelry.
Cut and Quality
Faceting enhances the gemstone's color, transparency, and internal light reflections. The quality of a faceted ruby is primarily evaluated based on color saturation and uniformity, clarity, cut proportions, and overall appearance. Commercial-grade rubies commonly contain visible natural inclusions and exhibit lower transparency, making them more affordable than high-quality gem-grade specimens.
