Due to their characteristics and their scarcity, diamonds have always been a sound investment.


Investment diamonds are a safe haven

Their rarity gives them a very high value, in a very low volume. In comparison, a 1-carat or 0.2g diamond can have the same value as a 1 kg bar of gold. As is the case for gold, the value of diamonds increases naturally and regularly depending on depletion of the resource.

Diamonds are unalterable. Consequently, they require no special precautions and are generally kept in a safe.


Characteristics of investment diamonds

All diamonds increase in value over the years but only diamonds of an exceptional quality really stand out in terms of added value.

The following are the quality criteria that are necessary if the diamonds are to be a good long-term investment :

  • Proportions, symmetry, polishing : Very Good or Excellent
  • Fluorescence : None or Slight/Faint

In its January 2014 edition, the magazine Gestion de Fortune devoted an article to investment in diamonds. Here is an excerpt: “For Nicolas de Saint-Yvi, director of Diamant-Gems ‘diamonds for investment are those that have the highest ratings in terms of colour, clarity and size […] an individual who purchased a high-quality investment diamond in 2010, kept it sealed in a safe for two years and sold it in 2012, made a capital gain of 15 to 20 %”.
