Gemstone Fracture Filling
Purpose: Used to fill fractures or cavities in gemstones (e.g., rubies, sapphires) with substances like resin to improve appearance and value.
Main Components:
- Vacuum Chamber (top section): Where the gemstone is placed for treatment
- Hand Screw/Handle: Used to secure and seal the chamber
- Digital Control Panel: Allows for control of temperature, time, and vacuum level
- Vacuum Pump (internal): Removes air from fractures to allow filler to penetrate deeply
- Switches: For general operation and vacuum pump activation
