What is a Ruby?

Rubies are a mineral compound called corundum which is Aluminum Oxide with trace minerals like chromium that cause it to be red in color. Although ruby is corundum just like sapphire it is its red color that sets it apart from all other colors of corundum. The name Ruby comes from the Latin word for red (ruber). Ruby has a Moh’s hardness scale rating of 9 out of 10 and is only scratched or marked by diamonds. Ruby is one of the most popular precious gemstones in the world and resources are limited so they hold there value long term.

Lab created ruby also called man made

Can rubies be synthesized?

Yes Ruby can be created artificially in a laboratory environment by several different processes most are created by the HPHT (high pressure high temperature) . Ruby can also be grown in a lab using a vapor deposition process. Synthesized ruby can be identified in a number of ways, even though they are chemically the same as natural earth mined stones. Under a microscope the growth lines will be curved and occasionally microscopic bubbles can form doing the growth process. Also traces of lead can be detected in these lab created stones.

Are rubies treated or enhanced?

Not all rubies are treated but nearly all rubies are treated or enhanced in some manner other than the cutting and polishing process. Ruby can be treated in a number of ways such as heating, glass filling, impregnation of color and surface coloring or waxes. A complete list and codes for treatment processes of gemstones is published by the American Gemstone Trade Association.
