    hi all! I want to know more about "High Pressure High Temperature"
    diamond coloration. Here are few quick questions; 

    Do jewelers in US send clear ones for the processing? 

    What is the price of colored diamonds after value addition? 

    Do they also use HPHT for removing inclusions and other defects? 

    Can anyone here give me per carat rates and the market demand/ fad
    worldwide? 

    I am quite hungry for the information on this subject...please
    enlighten! 

Thanks in advance
Sandeep
