Known as the "King of Gems" in Sanskrit, ruby is one of the most desired and valuable gemstones, prized as far back as biblical times. Ruby is the most valuable variety of corundum and commands the highest per-carat price of any colored stone. The trace element chromium is responsible for its color, which ranges from orangy red to purplish red — with pure, vivid red to slightly purplish red being the most highly valued. Some inclusions are to be expected, as inclusion-free rubies are exceptionally rare. Heat treatment is standard practice, as nearly all rubies available today undergo some form of heat treatment. Ruby is also the birthstone of July, making it a perennially popular choice for fine jewelry.

Clean with warm, soapy water. Use of an ultrasonic or steam cleaner is generally safe.
