ReneRubies are made of the mineral corundum, which is composed of aluminum oxide with the element chromium giving the gemstone its red color. The intensity and shade of red in rubies can vary based on the amount of chromium present in the crystal structure. Inclusions of other minerals or elements can also affect the ruby's appearance and value.

How synthetic rubies differ from natural rubies?
Synthetic rubies are created in a lab using similar chemical components as natural rubies, but they are made under controlled conditions and typically have fewer inclusions. This often results in a more uniform color and higher clarity compared to natural rubies. Additionally, natural rubies are formed in the earth's crust over millions of years, while synthetic rubies are created in a matter of weeks.
Can rubies be green?
Yes, rubies can be green. Green rubies are rare and are typically a result of the presence of chromium impurities in the gemstone. These green rubies are often referred to as "chrome rubies" due to the chromium content giving them their green color.
Are cut or uncut rubies worth more?
Uncut rubies are generally worth less than cut rubies because the cutting process adds value by enhancing their brilliance and color. Cut rubies are also easier to set into jewelry and more desirable to consumers for their finished appearance.
Where are rubies mined?
Rubies are mined in countries such as Myanmar, Thailand, Sri Lanka, and Madagascar. Myanmar, formerly known as Burma, produces some of the finest rubies in the world, particularly from the famous Mogok region.
Why are rubies semi-precious?
Rubies are considered semi-precious due to their relative abundance compared to other precious gemstones like diamonds. While rubies are highly valued for their color and clarity, the availability of large, high-quality rubies prevents them from being classified as a precious gemstone.
