What Is A Precious Stone?

What is the difference between precious stones and semi precious stones? These terms are based on old traditions from the west. These days, all gemstones are considered precious since they are all rare and there is a limited supply of them.

The traditional list of gemstones that are considered precious stones are:

• Diamond
• Ruby

All other gemstones are considered as being semi precious stones. These are old terms and not necessarily true these days. To view the treatments associated with each of these stones, visit our Technical Information On Gemstones page.
