Raw Ruby Emerald Sapphire 13.79 CT 

 

Raw ruby, emerald, and sapphire are the most coveted precious colored gemstones in the world. While rubies and sapphires share the same base mineral—corundum—emeralds belong to the beryl family. In their natural, uncut, or "rough" state, these stones look like unassuming, earthy crystals rather than polished jewels. 

 

Core Differences

 

  • Mineral Composition: Rubies and sapphires are made of crystallized aluminum oxide (corundum). Emeralds are composed of beryllium aluminum silicate. 
  • Color Cause: Chromium gives rubies their red color. Trace elements like iron and titanium create blue and various other colors in sapphires. Chromium and vanadium give emeralds their iconic green. 
  • Durability (Mohs Scale): Rubies and sapphires score a 9 in hardness, making them second only to diamonds. Emeralds are softer, scoring a 7.5 to 8. 

 

Identifying in the Rough

 

  • Natural Luster: Raw corundum (ruby/sapphire) can sometimes look opaque, heavy, and greasily textured, often found embedded in metamorphic host rocks like marble or schist. 
  • Emerald Inclusions: Raw emeralds are rarely flawless. They tend to show characteristic internal fractures (often called a "jardin" or garden) and have a hexagonal crystal structure.
