Tsavorite: The Rare Green Garnet and Emerald Alternative
Tsavorite is a green gemstone from the garnet family, specifically a variety of grossular. Its colour runs from bright to deep green and it has a sharp, lively brilliance, which is why it is often chosen by people who want a green stone other than emerald.
Origin and history
Tsavorite is a relatively new gemstone. Geologist Campbell Bridges found it in Tanzania in 1967 and later in Kenya. It is named after Tsavo National Park in Kenya and became widely known in the 1970s. East Africa, mainly Kenya and Tanzania, remains the principal source.
Characteristics of tsavorite
- Colour: green caused by vanadium and chromium. A pure, saturated green that still looks bright is the most sought after.
- Hardness: about 7 to 7.5 on the Mohs scale, suitable for jewelry with sensible wear.
- Brilliance: a high refractive index for a coloured stone, so it returns light vividly.
- Treatment: tsavorite is generally not heated or oiled. The colour is natural.
- Size: clean stones above 2 carats are rare, so prices rise sharply in larger sizes.
Tsavorite or emerald?
Both are green, but they behave differently. Emerald is a variety of beryl that almost always has inclusions and is commonly oiled to improve its appearance. Tsavorite tends to be cleaner, more brilliant and usually untreated. Emerald has the famous name and history, while tsavorite wins on clarity and sparkle.
How to choose a tsavorite
- Put colour first: an even green that is neither too dark nor yellowish.
- Check clarity with the naked eye. A good tsavorite looks clean.
- Choose a cut that returns light evenly across the stone.
- Ask the seller for a statement of authenticity, and for higher-value stones a report from a gemological laboratory.
- For a ring worn daily, choose a setting that protects the edges of the stone.
Caring for tsavorite
Clean it with warm water, mild soap and a soft brush. Avoid sudden temperature changes and hard knocks, and store it apart from harder stones such as diamond or sapphire so it does not get scratched.
