There are a number of ways in which diamonds can be ‘treated’. Care should be taken when repairing any jewellery containing treated diamonds. If you know the diamonds it treated, tell the jeweler!
- Laser drilled: The drilling literally ‘burns’ out an inclusion. Can sometimes be seen as a fine line or tube.
- Fracture filled: Laser drilled and filled with a ‘ceramic’ type substance close in density to diamond. The filling lessens the ability to see the inclusions. Can sometimes be detected by a faint mauve ‘flash’ under magnification.
- Irradiated: Artificially coloured by electron bombardment. The coloration is permanent and typically includes green, blue and yellow.
