Ruby
Ruby
(A Second Precious Gemstone)
A ruby is a pink to blood-red colored gemstone. It is a variety of the corundum. The red color is caused mainly by the presence of the element chromium in its composition. The ruby is considered one of the four precious stones, together with sapphire, emerald and the diamond.
Prices of rubies are primarily determined by its color. The brightest and most valuable blood-red color commands a large premium over other rubies of similar quality. After color follows clarity, a clear stone will command a premium. But a ruby without any needle-like rutile inclusions may indicate that the stone has been treated. Cut and weight are also an important factor in determining the price. Ruby is the traditional birthstone for July and is always lighter red.
Natural occurrence
Burma was for centuries the world's main source for rubies. That region has produced some of the finest rubies ever mined in the world. The very best color in Myanmar rubies is sometimes described as "pigeon's blood". Myanmar producing rubies during the 1990s and rapidly became the world's main ruby mining area.Rubies have historically been mined in Thailand, Burma, India, Afghanistan, Australia, Namibia, Colombia, Japan, Brazil and Pakistan. After the Second World War ruby deposits were found in Pakistan, Tanzania, Madagascar, Vietnam, Nepal and Tajikistan.

Facebook (formerly Thefacebook) is an online social networking service headquartered in Menlo Park, California. Its website was launched on February 4, 2004, by Mark Zuckerberg with his college roommates and fellow Harvard University students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. The founders had initially limited the website's membership to Harvard students, but later expanded it to colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities and later to high-school students. Since 2006, anyone who is at least 13 years old is allowed to become a registered user of the website, though the age requirement may be higher depending on applicable local laws. Its name comes from a colloquialism for the directory given to it by American universities students.
After registering to use the site, users can create a user profile, add other users as "friends", exchange messages, post status updates and photos, share videos and receive notifications when others update their profiles. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as "People From Work" or "Close Friends". Facebook had over 1.3 billion active users as of June 2014. Due to the large volume of data users submit to the service, Facebook has come under scrutiny for their privacy policies. Facebook, Inc. held its initial public offering in February 2012 and began selling stock to the public three months later, reaching an original peak market capitalization of $104 billion. As of February 2015 Facebook reached a market capitalization of $212 Billion.
