Frequently Asked Questions
How do I tell what type an individual zircon is?

Low zircon’s crystal structure has been altered by thousands of years of irradiation from its own trace elements. It’s typically dark green. High zircon’s gemological properties are higher, so type can be determined with standard gemological testing. Most gems used in jewelry are high zircon.
