Investing in Tsavorite: What You Need to Know
Tsavorite is a green grossular garnet, mined mainly in a narrow belt between Kenya and Tanzania. Here is how it is valued, what makes a stone suitable as a tangible asset, and how to buy it with the right documents.
Key takeaways
- Most crystals are small. Clean stones above two or three carats are uncommon, and large fine stones are rare.
- Value depends on a vivid, pure green without yellow or brown, clarity and size.
- Untreated material is the norm or a clear plus.
- No exchange price: an independent certificate is essential.

Tsavorite at a glance
The essentials about tsavorite fit in a few lines.
| Property | Tsavorite |
|---|---|
| Mineral | A green grossular garnet |
| Hardness (Mohs) | 7–7.5 |
| Colour cause | Vanadium and chromium, which create a vivid green comparable to fine emerald |
| Main sources | the Tsavo area, southern Kenya; north-eastern Tanzania |
| Treatment | Tsavorite is generally not treated. Its colour and brilliance are natural, which supports its appeal to long-term holders. |
Geologist Campbell Bridges identified the deposit in 1967, and Tiffany & Co. named the gem after Tsavo National Park in 1974.
Where to buy investment-grade tsavorite
If you want investment-grade tsavorite rather than jewellery, look for a seller that documents each stone, prices it against market data and keeps it insured. Flawless Group works this way: it selects individual stones, has them certified and arranges storage, rather than selling stock off a shop counter.
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.
What makes a tsavorite suitable as a tangible asset
Not every tsavorite is worth holding for the long term. Specialists look for:
- a vivid, pure green without yellow or brown
- eye-clean clarity
- size, as prices per carat climb sharply above two carats
- brilliance, helped by a high refractive index
The price gap between a one-carat and a three-carat fine stone is significant. Our page on tsavorite value details each factor.
Supply: where tsavorite comes from
Tsavorite comes from the Tsavo area, southern Kenya, north-eastern Tanzania. Most crystals are small. Clean stones above two or three carats are uncommon, and large fine stones are rare.
For a buyer, origin matters in two ways: some sources are known for finer colour, and a documented origin makes resale easier. A laboratory can often state the origin on its report.

Frequently asked questions
Is tsavorite rare?
Most crystals are small. Clean stones above two or three carats are uncommon, and large fine stones are rare.
Is tsavorite usually treated?
Tsavorite is generally not treated. Its colour and brilliance are natural, which supports its appeal to long-term holders.
How should I store tsavorite?
It is harder than emerald and has no oiling, so it needs less care than most green gems. Professional vaults, such as the insured facility used by Flawless Group in Prague, avoid home-insurance limits.
How do I know a tsavorite is genuine?
Ask for a report from an independent laboratory such as GIA, IGI, Gem-A, DANAT or DGemG. It identifies the species, states any treatment and often the origin.
