Investment natural diamonds are cut gemstones of the highest quality, intended primarily for capital preservation, not just for jewelry. They form deep in the Earth's mantle over millions of years and their supply is limited – natural diamond mining has been declining long-term, and new significant deposits appear only rarely.
An investment diamond is typically considered a stone that:

Natural diamonds are one of the most stable ways to preserve your capital. Unlike other assets, they offer a unique combination of physical beauty and investment value.
Natural diamond mining has been declining for a long time and new significant deposits appear only rarely. This creates natural scarcity and potential for value growth.
Diamonds maintain their value over the long term and are considered a safe haven during times of economic uncertainty.
Enormous value in a small volume. A 1-carat diamond can be worth hundreds of thousands, yet is completely portable and easy to store.
Diamonds can be traveled with and transferred between countries very easily. Due to their small volume, they are logistically undemanding.
A combination of gold, silver, platinum and diamonds helps spread risks and reduce dependence on a single asset class.
When choosing an investment diamond, it's good to proceed systematically. We'll help you with a complete proposal and comparison of options, but it's still useful to know the basic steps.
Clarify your budget and investment horizon. Think about how much of your portfolio you want to move into diamonds and for how long. Diamonds are more suitable for medium to long-term holding.
Higher weight (in carats) means significantly better long-term tradability. Stones from approximately 0.5 ct and above are often chosen, depending on the investor's budget.
It's generally better to own one higher-quality diamond than multiple stones of lesser quality. Investment diamonds should have higher color and clarity grades, which are most sought after in the market.
Every investment diamond should have an international certificate (GIA, IGI or HRD), which precisely describes its parameters. The certificate greatly facilitates future sale.
The Rapaport price list helps with price orientation and is a globally recognized reference for trading natural diamonds.
For basic orientation among the main parameters, often referred to as the 4Cs, the price composition is based on the parameters below.
The diamond's shape (round brilliant, oval, cushion, princess, etc.) affects its appearance and demand – round brilliants are the most popular and sought after, so they often hold higher prices in investment portfolios.
Diamond weight is measured in carats (ct). The higher the weight – the larger the diamond, the faster the price per carat grows. Diamonds around 1 ct and above are therefore more interesting from an investment portfolio perspective.
The color of standard diamonds is graded on a scale from D ("whitest") to various yellowish or brownish tints. Investment diamonds choose higher color grades which are more profitable and liquid:
Colors G–I = investment grade, very white
Colors D–F = best price/quality ratio in investment grades, depending on the specific strategy.
Clarity describes the amount and type of inclusions and surface blemishes. A diamond with higher clarity is rarer and more valuable. In practice, a combination of quality color and good clarity is often chosen, offering the best price and liquidity.
All these parameters (Shape, weight, color, clarity) are reflected in the price and future tradability of the diamond. Therefore, we strongly recommend consulting with an expert for selection.
| COLOR | CLARITY | SIZE | CUT |
|---|---|---|---|
| D | FL | 0.30 ct | EXCELLENT |

| F | VVS1 | 0.50 ct | VERY GOOD |
| G | VVS2 | 0.70 ct | |
| H | VS1 | 1.00 ct | GOOD |
| I | VS2 | 1.50 ct | |
| J | SI1 | 2.00 ct | |

The global standard for pricing natural cut diamonds is the Rapaport Price List. It's a reference price list that is regularly published and serves as the basis for wholesale diamond prices on world markets.
The price list is structured according to:
The final market price of a specific diamond is then derived from this reference basis. Dealers typically provide a discount or premium to the Rapaport price list depending on the specific stone, its demand, and other parameters (e.g., fluorescence, exact shape, cut proportions).
