Composite Emerald

Treatment: Composite Stone

Identification Tools Required: Magnification and possibly immersion cell.

How to Identify:

Primary Test: Magnification should be all you need. These stones will have multiple layers with a glue layer somewhere in between. You will virtually always find gas bubbles somewhere in the glue layer as seen below. You may need to use the immersion cell to be able to see these clearly.

Secondary Tests: None should be necessary.

Repair and Setting: Extreme caution with this material as any heating, including boiling, may cause the composite layers to separate. Customer should be informed of the composite nature of the stone before any repairs or resetting is initiated. No heat, no ultrasonic, and no cleaning solutions of any type.
