Princess cut Diamonds are in high demand and can increase in value over time. The key will be size and clarity. Small princess cut Diamonds with what the industry calls melee would not increase in value. But a one Carat VS1 or better has the potential to increase in value over time. The most sought after of course is the round brilliant Diamond which I wrote about earlier. So to answer this question Diamonds can be a decent investment, but I would view Diamonds as more of a sentimental piece than a great investment.
