Round Genuine Ruby Cabochon

Known as the "King of Gems" in sanskrit, Ruby is one of the most desired and valuable of gemstones as far back as biblical times. Ruby is the most valuable variety of corundum and has the highest per-carat price of any colored stone. The trace element of chromium is responsible with the color, with color ranging from orangy red to purplish red. Pure, vivid red to slightly purplish red is the highest valued color. Some inclusions are to be expected as inclusion-free rubies are very rare. Heat treatment is also standard, as almost all of today's rubies undergo some type of heat treatment. Clean with warm, soapy water. Use of ultrasonic and steam cleaner is usually safe.

• Translucent to opaque, medium pinkish red, eye-visible inclusions
