The bigger the diamond, the higher its rarity in nature. This makes it a rarity as it occurred only rarely two billion years ago. As the rarity increases the price also increases disproportionately: An internally flawless 2-carat diamond, for instance, will always cost more than two internally flawless one-carat diamonds of the same quality amounting to two carats together.

The two-carat diamond as an investment

A 2-carat diamond is just the right thing for those who are looking for a mobile way to store larger amounts of value. Even though it only weighs 0.4 grams (1 carat = 0.2 grams), it has a value equivalent to over 2 kilos of gold. This means that the bigger the stone is, the higher its value concentration is as well.

What you should know about diamonds as asset protection:

The search for the right investment for asset protection seems to be becoming more and more difficult. Stocks and bonds have become too fraught with risk. Investors have therefore been showing more and more interest in diamonds as a material asset. This is because a diamond has decisive advantages: The price of diamonds has increased over the last 25 years, for example. Even the influences of market conditions were unable to have a lasting effect on the price of diamonds. A diamond also holds the greatest value in the smallest space. An excellent brilliant-cut diamond weighing four carats (0.8 grams), for instance, is worth as much as 10 kg of gold, approximately 350,000 euros. These and numerous other advantages make the diamond a valuable investment for the future.

Information for investors in diamonds

DIAMONDAS customers tell us that they secure approximately 5% of their assets through the purchase of investment diamonds. This investment in diamonds is intended to secure your assets in the long term for generations. It is primarily diamonds that have always been highly valued as "the world's hardest currency" (Frankfurter Allgemeine Zeitung): They have maintained their value through all political and economic events.

The selling prices stated in euros are based on the current exchange rate with the US dollar and include the applicable VAT at that time.

Diamonds require experience and expertise.

Experience and professional expertise are of the highest priority in the world of diamonds. Even the smallest, barely perceivable nuances have a major influence on the price as well as the resale potential of a diamond. Diamonds should therefore only be purchased from specialists with many years of experience in this specific line of work.

Even the smallest crystalline pinpoint inclusions that are only visible to the human eye under greater than 10 times magnification greatly influence the quality and thereby the price of a diamond as well. Only experts with many years of experience can correctly appraise the quality and price of a diamond.

The two-person rule is always used at DIAMONDAS to ensure the quality of the investment diamonds offered: Each diamond is inspected by at least two diamond experts to verify that it exhibits the qualities indicated in the certificate and to verify the identity of the gemstone and the certificate.
