Why diamonds?

Why diamonds as an investment?

  • Inflation hedge as a tangible asset
  • Stable performance
  • Tradable worldwide
  • High concentration of value
  • High mobility
  • Untouchable for the taxing machinery compared to real estate
  • Few large companies control production and hence the supply of diamonds
Diamonds are suitable as an inflation hedge like other tangible assets. Another plus is the stable development of diamond prices over the decades. Many investors also appreciate the fact that one can trade diamonds all over the world. By highly concentrating value diamonds are easy to both store and move. Comparing diamonds to gold: 1kg of gold costs about 35.000 EURO while the same value in diamonds can be achieved already by 1 to 1.5 carats (0.2 to 0.3 grams). In comparison to real estate there is no dependency on location. And tax authorities cannot raise any fees like on property.

Even though the well-known diamond mining company De Beers does not have a monopoly in the diamond trade any longer, there are only a few large companies that control the production of rough diamonds. De Beers together with the Russian company ALROSA account for about 70% of all diamond production worldwide. In case demand for diamonds is weakening it is in the interest of these two big players to shorten supply and support diamond prices by doing so.

Possible disadvantages of diamonds as an investment

Although every diamond can be used in jewelry at any time, there are risks that one needs to take into consideration.

  • The complexity of the matter. Which diamonds are suitable for investments? What are possible price developments in the future and what do they depend on? Our advice: Ask an expert for counsel. How do you explain price differences by the different parameters and qualities? A one carat diamond is not like any other one carat diamond. Investors should know more than jewelry lovers.
  • Diamonds are subject to VAT. That is, when liquidating your brilliant asset selling to a third person you can also claim this money. However, if you are selling to the trade you will lose the VAT you have paid. In case you have questions on how to sell a diamond talk to us. We can always make you an offer and/or help you sell to a private third party. Our contacts into the industry have proven useful here.
  • Diamonds are not suitable for short-term investments only due to the VAT. Their prices grow steady, but slowly. Every percent of inflation over the years works towards your increasing value of diamonds.

Possibilities and Strategies

Essentially, there are two main strategies to invest in diamonds:

I. Buying diamonds of commercial quality for which there is constant high demand.

II. Buying diamonds of premium quality only that are extremely rare.For both strategies you should consider the following parameters:

  • Round brilliant is by far the most popular diamond shape. More than 75% of all customers decide for a round brilliant diamond.
  • Common sizes: 0.5 carats, 0.75 carats, 1 carats, 1.25 carats, 1.5 carats or 2 carats
Most diamond lovers prefer these standard sizes.
  • No fluorescence. Even though many customers are enthusiastic about the phenomena of fluorescence and it can actually have a positive effect on diamond color: The market discounts fluorescent stones. When thinking about an investment, stick to what the market believes is right.
  • GIA Certificate. Other certificates can be just as good, however, we advise you to only go for GIA certificates when you buy as an investment.

Strategy I:
Adjust your diamond portfolio for above-average, but not for the highest qualities.

This means:

Carat weight: 0.50 to 2 ctCut: Very good – excellent
Clarity: VS1 – VS2Polish: Very good – excellent
Clarity: VS1 – VS2Symmetry: Very good – excellent
These combinations are preferred in the production of jewelry and hence there will always be a demand for these types of diamonds. Every jeweler can make use of them and the chance of finding a private buyer is comparably high.

Strategy II:
Only buy diamonds of the highest quality.

This means:

Carat weight: 1 to 3 ctCut: Excellent
Color: D – EPolish: Excellent
Clarity: FL – IF
Symmetry: Excellent
This combination is rare by nature, upscale and stable in value. The potential buyer clientele is smaller than for commercial diamonds which makes the investment rather long-breathed. At the same time the increase in value tends to be greater among stones of the highest quality.

What we do not recommend:

Diamonds that are most suitable to be set in jewelry might not be the best choice for an investment. For instance a pear shape diamond with strong fluorescence of 1.34 carats and a low color degree. This can fit perfectly in a beautiful piece of jewelry and look fantastic, yet, it might be difficult to sell. The same goes for objects of vertu: Very large or colored diamonds that are among the most expensive precious stones that exist, are very valuable, but not fungible when it comes to selling it again. One might consider it a quite specific market niche and not a mainstream product.
