How Diamonds are Treated

Diamonds are often treated. If you are concerned about getting true value for your money, know what you are getting.

• Filled for clarity: Diamonds with inclusions are sometimes filled with glass to make them appear clearer. Yehuda Diamonds have undergone this treatment. Filler can be damaged by heat, ultrasonic cleaning, and by re-tipping. The filling does not repair the inclusion, it just makes it less visible.

  If you look at a filled diamond closely, rotate it under light, you should be able to notice a bluish flash. Yehuda will usually refill your diamond for free if it is ever damaged. Check for guarantees before buying such a diamond.

• Irradiated for color: Can be affected by heat.

• Painted for color: Can be painted to offset a yellow tinge. The paint wears off rather quickly.

• Ask if the diamond you are considering buying is treated. Getting a notarized statement from your jeweler saying that your diamond in not treated is recommended. This is like having the jeweler swear under oath that to his/her knowledge that the diamond is not treated. Several states have disclosure acts requiring dealers to tell you about these treatments.
