Corundum (variety: Ruby)
Rubies are still one of the most popular and valuable gemstones today. The most important source of fine rubies sine the late 15th century has been Burma. Burmese rubies are generally considered to be the finest color and are often referred to as "pigeon's blood." Another major source of rubies today is Thailand, near the Cambodian border. The stones are typically brownish-red and darker than those from Burma and are commonly heat-treated to produce a purer red color. The 3.89-carat ruby in the ring pictured here is from Thailand.
