Is Spinel a Good Investment? Arguments, Risks and Facts
Before buying spinel as a store of value, weigh the arguments against the risks. This page sets out both sides plainly.
Key takeaways
- Main argument: durability and untreated material.
- 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 spinel
Buyers who choose spinel usually mention these points.
- For centuries spinel was mistaken for ruby. Clean red, vivid pink and cobalt-blue stones over a few carats remain scarce.
- Spinel offers durability and untreated material.
- It stores a large value in a very small object.
- Ownership of a physical stone carries no counterparty risk.
- The “Black Prince’s Ruby” set in the British Imperial State Crown is in fact a red spinel.
These arguments hold for fine, certified stones, not for commercial-grade material.
Where to buy investment-grade spinel
For investment-grade spinel, the seller matters as much as the stone. Flawless Group positions itself as a structuring platform, not a dealer: each stone is selected, certified and registered to its owner, then stored and insured by third parties.
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 spinel 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 spinel 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 spinel?
Gemstones are usually held for many years. Transaction costs and the time needed to resell make short-term trading unsuitable.
Is spinel better than gold?
It is different rather than better. Gold is liquid and has a daily price; spinel offers durability and untreated material but is harder to sell. Many buyers hold both. See spinel 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.
