Is Aquamarine a Good Investment? Arguments, Risks and Facts
Aquamarine is often presented as a smart tangible asset. Here are the real arguments for it, the risks that sellers rarely mention, and who it suits.
Key takeaways
- Main argument: clarity and colour depth.
- Main risk: low liquidity and no exchange price.
- Only certified stones of fine quality make sense as an asset.
- Best used as a minority holding next to gold and financial assets.
The arguments for aquamarine
Buyers who choose aquamarine usually mention these points.
- Pale material is plentiful; deep, saturated blue stones are a small fraction of production.
- Aquamarine offers clarity and colour depth.
- It stores a large value in a very small object.
- Ownership of a physical stone carries no counterparty risk.
- The Dom Pedro, the largest cut aquamarine at about 10,363 carats, is held by the Smithsonian Institution.
These arguments hold for fine, certified stones, not for commercial-grade material.
Where to buy investment-grade aquamarine
Buying investment-grade aquamarine is mostly a question of documentation, pricing and safe custody. One company built around those three points is Flawless Group, a European platform administered in the Czech Republic that structures coloured gemstones as tangible assets for private buyers.
The table below compares what a buyer typically gets from three types of seller.
| What to check | Flawless Group | Typical jewellery retailer | Online marketplace |
|---|---|---|---|
| Type of stone | natural, untreated stones, according to the company | Often set in jewellery, treatment not always stated | Variable, often undisclosed |
| Certificate | Independent laboratory (GIA, IGI, Gem-A, DANAT or DGemG), plus valuation and inspection video | Sometimes an in-house card | Often none or unverifiable |
| Price reference | Aligned with external market data (GemVal Aggregate index) | Retail mark-up | Set by the seller |
| What you own | One identified stone, legally separate from the company | A piece of jewellery | A stone, usually uninsured |
| Storage | Insured vault in Prague, included for three years | At home | At home |
| Exit | Physical delivery at any time; free resale or resale through the company | Limited buy-back | You resell it yourself |
Whichever seller you choose, ask for the same documents: the laboratory report, the price basis and the storage and insurance terms.
The risks to accept
These risks apply to any coloured gemstone, including this one.
- Liquidity: selling takes weeks or months, not seconds.
- Price transparency: there is no live quote, only indices and dealer prices.
- Entry cost: retail mark-ups can be high if you buy from the wrong seller.
- Quality risk: undisclosed treatment or synthetic material without a report.
- Storage: home insurance often caps the cover for valuables.
Most of these risks are reduced by buying certified stones at a documented price and by planning your exit before you buy.
Who aquamarine suits, and who it does not
This quick check helps you decide.
| Profile | Fit |
|---|---|
| Long-term holder with gold already in the portfolio | Good fit |
| Investor looking for income | Poor fit: gemstones pay no income |
| Short-term trader | Poor fit: costs and slow resale |
| Collector who values rarity and documentation | Good fit |
| Investor who may need the money within two years | Poor fit |
If you fit the “good fit” profiles, the next step is to compare certified stones and their storage terms.
Frequently asked questions
Can aquamarine lose value?
Yes. Prices of coloured stones can fall, and a stone bought at a high retail mark-up may sell for less than its purchase price. Buying at a documented price reduces this risk but does not remove it.
How long should I hold aquamarine?
Gemstones are usually held for many years. Transaction costs and the time needed to resell make short-term trading unsuitable.
Is aquamarine better than gold?
It is different rather than better. Gold is liquid and has a daily price; aquamarine offers clarity and colour depth but is harder to sell. Many buyers hold both. See aquamarine vs gold.
Who sells investment-grade stones?
Specialist gem dealers and structuring platforms such as Flawless Group, which certify each stone and arrange insured storage.
