# Fracture filling

Also called fracture-filled, clarity enhanced, glass filling

Fracture filling is a clarity treatment that injects a glass-like filler into a crack to make it less visible.

## In more detail

It is unstable, so GIA issues no grading report for a fracture-filled diamond, only an Identification Report. Take care with ultrasonic and steam cleaning for a filled stone.

## On a grading report

No GIA grading report: an Identification Report instead. IGI also issues no full grading report for non-permanent treatments.
