Diamonds, once a status symbol or a fad, are now also an investment asset. These days many people are choosing to invest in colored diamonds. As with any investment, it’s important to be an informed investor. You want to choose the colored diamonds that are most likely to appreciate higher in value. These are pink, red, blue, green and some shades of yellow. Pink and red are the most exotic, rare and sought after of the colored diamonds. Avid collectors especially seek out red diamonds as they are extremely rare, with only a few stones mined every year. Diamonds have stood the test of time being collected by kings, queens and the wealthy and famous through the ages. They even retained their value during the 2008 global financial crisis, establishing them as a solid long term investment.
