A diamond portfolio sale is set to sparkle in Singapore
Diamonds, we were told by Marilyn Monroe in the movie "Gentlemen Prefer Blondes", are a girl's best friend.
But they have also been a firm favourite of many investors as well.
So, how do they compare with other traditional commodities, such as gold and silver?
On Wednesday, the newly-established Singapore Diamond Exchange aims to answer some of those questions with its first official sale of a diamond portfolio.
Shlomo Tidhar is the CEO of the Exchange, known as SDX, and he told the BBC's Asia Business Report that diamonds are a solid investment.
