Actually i feel that pink color suits more on teenagers and so they like it.
And if we talk about diamond then it's well and good.Because jewelry are the most important factor in womens overall packaging of makeup.If we talk about pink diamond it will definitely give some kind of boost in the looks of girls or womens.
Apart from this now a days every one is interested to look
"different + fancy + unique" 
.So,it can be possible only if u have something different designs in dress,jewelries and makeup.
so,pink diamond is the good supporter for the above latest combination.
