A blue sapphire or a blue diamond as investment?

  • For centuries, the blue sapphire has been mined in Sri Lanka.
  • A blue diamond as investment is more interesting than a blue sapphire.
  • Unlike gems such as sapphires, buying diamonds is clearly defined in the international legislation.

The blue sapphire is rising in popularity in the jewellery world. Think, for example, of the engagement ring with blue sapphire of Lady Di, now sparkling around Kate Middleton’s finger. A blue sapphire is more affordable in price compared to the very rare, blue brilliant diamond. The  colour intensity, too, has a strong influence on the price of a diamond. Thus, a blue diamond trumps a blue sapphire as investment.


Since the second century A.D., sapphires have been mined in Sri Lanka. Even though the sapphire exists in many colours, the blue one is best known and loved. The iconic blue sapphires, cornflower blue or royal blue, are the most valuable. Are you looking for a gem or diamond as investment? Then the sapphire is less interesting. Are you attracted to the beautiful colours? Take a look at the reasons why to invest in coloured diamonds.


The increased demand for blue sapphires did lead to a gradual increase in value of this gemstone. The sapphire is an increasingly popular gemstone, and thus suitable as investment. But unlike this type of gem, buying a diamond as investment is clearly defined in the international legislation. When buying a diamond as investment, you will always receive a certificate, which protects both the investor, the trader and the jeweller. A certificate for a sapphire is possible, but less common.

Quality guarantee

When you are planning on buying a diamond as investment, this certification is very important. It is a guarantee of the diamond’s quality, and therefore the only way to make sure your investment is sellable at an interesting price. Because of this, more and more investors demand a certificate when buying a gemstone such as the sapphire.
