Heating a diamond

I have a large diamond that is SI2 and is H in color. I took it in to have a channel fixed as it had a nick in the gold and there are small diamonds in the channel. My large diamond has a purple tint to it now that was not there before. Can heating a ring and or stone cause it to change color and what could cause this.

Hi,

 

 

If the diamond was fracture filled, it is quite possible that the direct heat of the torch could damage the treatment and change the look of the diamond.

 

Do you have any information on the center diamond, such as a lab report?
