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 ruby's signature color, which ranges from orangy red to purplish red — with pure, vivid red to slightly purplish red representing the highest-valued hue.
These oval faceted genuine rubies are heat-treated, which is standard practice for virtually all rubies on the market today. Some inclusions are to be expected, as inclusion-free rubies are exceptionally rare. Available in multiple grades and sizes, these stones are well-suited for custom jewelry design, setting projects, and retail resale. Ruby is the birthstone of July. Clean with warm, soapy water; use of an ultrasonic or steam cleaner is generally considered safe.
