Rubyred_ is formed when aluminum-rich magma cools slowly underground. Over millions of years, impurities in the magma, including chromium, iron, and titanium, become concentrated, giving the gemstone its characteristic red color.

Geological Occurrence

Rubyred_ is primarily found in metamorphic rocks, such as marble and gneiss. It is also found in igneous rocks, such as granite and pegmatite. The leading sources of rubyred_ include:

• Myanmar (Burma): Known for producing the finest rubyred_, especially the "pigeon blood" variety.
• Thailand: A significant producer of high-quality rubyred_.
• Madagascar: Home to rubyred_ deposits with unique pinkish-red hues.
• Sri Lanka: Produces a range of rubyred_ colors, including orange-red and purplish-red.

Properties of Rubyred_

Rubyred_ possesses exceptional physical and optical properties that make it highly valued by gemologists and jewelers.

Hardness: Rubyred_ is one of the hardest natural materials, with a Mohs hardness of 9. This makes it highly resistant to scratching and wear.

Color: The red color of rubyred_ results from the presence of chromium ions. The intensity and shade of red vary depending on the chromium content.

Clarity: Rubyred_ is typically found with inclusions, known as "silk." These inclusions can give the gemstone a distinctive chatoyancy or silky appearance.

Optical Phenomena: Rubyred_ exhibits various optical phenomena, including fluorescence, phosphorescence, and asterism (a star-like effect).

Benefits and Uses of Rubyred_
