Is there a pink diamond

Yes. There are three sources of Pink Diamonds. The most valuable is an all natural Fancy Pink Diamond that is mined, with Fancy Pink Argyle diamonds being especially rare due to their Vivid Pink color. It will continue to increase in value as the mine is closing within a decade. A typical Fancy Pink Argyle can sell for $49k at only .24 ct. The larger they are, the more rare, and have double value per ct.

The second most valuable Pink Diamond is mined, but has been color enhanced by an expensive, high pressure high temperature process (HPHT). The stones are worth about $15k per ct if you get high clarity, high grade color (Fancy Vivid Pink). Color enhanced is NOT a clarity treated diamond. Pink diamonds that are coated and treated are crap because the color is not permanent.

The third source is a man made, lab produced Pink Diamond. They are great stones if you are looking for something more affordable. The Pink diamonds ARE colored diamonds, just not naturally mined. If you choose this option, you can get a really beautiful stone. Look for Deep Pinks and a high grade clarity (VS1) to maximize the value. These stones can easily go for a couple thousand per carat.
