Fracture Filling


Definition: Fracture filling is a treatment used to fill tiny cracks in a gemstone with a clear, glass-like substance. The cracks don't disappear, but the film creates an optical illusion that makes them invisible to the naked eye.

Fracture filling can wear away over time and with harsh treatment. Ask the jeweler for care and cleaning advice when you buy a fracture filled diamond.
