Is disclosure of fracture filling an industry requirement?

• A. Yes, disclosure of fracture filling is mandatory.
• B. No, disclosure is optional.
• C. Only required for certain markets.
• D. Only required in some cases when color changes have occurred.

Answer: (A)

Fracture filling is a treatment applied to diamonds to improve apparent clarity by filling cracks with a resin or glass. Because this treatment can affect a diamond’s durability, stability, and value, the trade requires clear disclosure so buyers aren’t misled about what they’re purchasing. Lab reports and industry guidelines consistently mandate that fracture-filled diamonds be disclosed, and this disclosure is communicated to customers in the market. This is why the correct stance is that disclosure is mandatory. It isn’t simply optional, it isn’t limited to certain markets, and it isn’t conditional on color changes—the fact that a fracture filling exists is the reason for disclosure, regardless of whether color is affected.
