Sapphires 101

What Does “Natural” & “Untreated” Mean?


What Does “Natural” & “Untreated” Mean?

The word “natural” identifies a sapphire crystal that has been developed in the ground, not synthetically created or treated in a lab.  The word  “Untreated” means that a sapphire has not undergone any heat or chemical treatments to improve its color or clarity.

Today, nearly all sapphire stones and jewelry  from online sources and in stores are described as “natural” if it isn’t a synthetic that is lab created. Don’t be misled, these “natural stones” may  come straight from the ground but their color and clarity are often results of chemical procedures or heat treatments. The color and clarity of these treated stones are often created through a heating process. During this high heat treatment, additives such as glass and coloring agents can be included to fill natural cavities and cracks in the sapphires. The coloring agents are then diffused  throughout the crystal, completely altering the stones original color.

New treatment protocols are continuously being developed.  Trained gemologists can often spot the telltale signs of gem treatments, but advanced technology is often used for 100% accuracy in treatment detection. Regardless, ethical business practices in the gem and jewelry industry require sellers to disclose any known treatments or enhancements, since they have a significant impact on the actual value of the gemstone itself.  Ethical sellers will provide customers with these certifications.
