Ruby is a dark pink to deep red gemstone. It is a member of the corundum mineral family, the second hardest natural mineral on the earth. The name “Ruby” comes from the Latin word for red, "ruber". Essentially it is a red sapphire.
In gemological terms a ruby has to be a blood-red color. However, any corundum with a red or reddish color is often called a "ruby".
Ruby mines are located in: Myanmar (Burma), Thailand, Cambodia, Afghanistan, Pakistan, Tanzania, Madagascar, Vietnam, Nepal and Tajikistan.
Value of Rubies
Rubies are graded according to the same criteria as diamonds, according to the 4Cs: colour, cut, clarity and carat (weight).
The most important criteria of determining the value of a ruby is colour, the darker the red of the stone, the more valuable the ruby.
The most valuable ruby colour is called "pigeon blood" ruby.
Considered one of the most precious and perfect gemstones, rubies are very popular in the jewellery industry including: pendants, rings, bracelets, earrings, brooches and tiaras. The ruby symbolizes the sun, freedom and power.
The Smithsonian's National Museum of Natural History in Washington D.C., currently holds in its collection one of the world's largest ruby gemstones set in a ring.

Rubies and Gemological Certification
Gems such as rubies are certified to verify the authenticity of the stone. A gemological certificate will often have a photograph of the stone and include information such as the weight, cut, measurements, enhancements, and any other essential features noted during the certification process.
Gemological certification institutes employ trained gemologists who use a variety of scientific methods and test equipment to thoroughly examine your ruby or gemstone.
When acquiring certification for your ruby, avoid certificates issued by the sellers themselves. In this case you should take the ruby to reputable independent organizations that are recognized in the industry, or, only buy a ruby that has already been certified by a recognized gemological institute.
