Physical properties

Formation & geological history

Manufactured through sintering of oxide powders and ion-exchange chemical processes in a laboratory setting to create high-durability consumer electronics components.

Uses & applications

Used in the technology industry for smartwatch backplates and displays due to scratch resistance, biocompatibility, and radio-frequency transparency.

Geological facts

The 'Ion-X' glass used is hardened at a molecular level by replacing smaller sodium ions with larger potassium ions to create a compression layer. The zirconia back allows for wireless induction charging.

Field identification & locations

Identify by 'Series 2' markings and 38mm Aluminum Case text. Found globally in consumer electronics markets. It is not a natural geological specimen but a high-tech synthetic assembly.
