Green Gemstones: Names, Shades and How to Tell Them Apart
The greens by name, the ones that last in a ring, and the color line where an emerald becomes a green beryl.
The green gemstones you will meet most are emerald, tsavorite garnet, tourmaline and peridot, then green sapphire, chrysoberyl, demantoid and jade. Emerald has the finest green, and asks for care. For a ring worn every day, green sapphire and chrysoberyl are the safest choices. Before you choose, ask two things: does the stone deserve its name, and was it treated?
| Green stone | Hardness (Mohs) | Everyday ring? |
|---|---|---|
| Green sapphire | 9 | Yes |
| Chrysoberyl | 8½ | Yes |
| Emerald | 7½ to 8 | Yes, with care: often filled |
| Tsavorite, tourmaline | 7 to 7½ | Yes |
| Jade | 6 to 7 | Yes: very tough |
| Peridot, demantoid | 6½ to 7 | Earrings, pendants, or with care |
What Are the Green Gemstones Called?
Green gemstones fall into three groups, and the shade is often your first clue to the name.
- Bluish green to pure green. Emerald, tsavorite garnet, chrome tourmaline (the tourmaline guide) and, at the blue end, teal sapphire.
- Yellowish green. Peridot (the August birthstone), chrysoberyl, demantoid garnet and green sapphire (how to find a bright green sapphire).
- Translucent to opaque. Jadeite and nephrite jade, green chalcedony, malachite.

Diopside and sphene turn up less often, and zircon comes in green too.
Why do two greens look so different? Chromium and vanadium make the richest greens: emerald, tsavorite, chrome tourmaline, demantoid, the finest jadeite. Iron makes green too, in peridot, and with titanium in green sapphire, but a more muted one.
Which Green Gemstones Last in a Ring?
Dust in the air is mostly quartz, hardness 7. A stone below 7 slowly loses its polish on the hand.
Eight green stones: hardness and toughness
Hardness is resistance to scratches, toughness is resistance to knocks. A ring needs both.

Green sapphire Mohs 9 · Toughness: Usually excellent
9 on the Mohs scale and usually excellent toughness: an excellent ring stone.

8.5 on the Mohs scale and excellent toughness: a very good ring stone.
Emerald Mohs 7.5 to 8 · Toughness: Poor to good
7.5 to 8 on the Mohs scale, but its inclusions make toughness run from poor to good. A ring stone that needs care.

Points that would overlap are moved apart a little. The exact values are in the table.
Toughness has no number: it is rated in words, and one stone can sit on two lines. Inclusions, fractures or some treatments lower it for any single stone.

- Green sapphire. An excellent ring stone.
- Chrysoberyl. Hard, with excellent toughness.
- Emerald. Hard enough, but inclusions and fillings make it fragile.
- Tsavorite and tourmaline. Good ring stones.
- Jade. Softer than dust at the low end, yet so tough it still makes a good ring stone.
Peridot and demantoid suit earrings and pendants, or a ring worn with care. Diopside and malachite belong in earrings and pendants. Settings and cleaning, stone by stone: green gemstone rings.
Is a Green Gemstone a Precious Stone?
By trade custom, four stones are called precious: diamond, ruby, sapphire and emerald. In green, that means emerald, green sapphire and green diamond. Nothing else.
The label is outdated, and the ranking it suggests is inaccurate. Large, fine tsavorite and demantoid are among the rarest and most valuable colored gems, and neither is on the list. Here is what “semi-precious” really says about a stone.
When Does a Green Stone Lose Its Name?
Two green names stop at a color line. An emerald too light in color is sold as green beryl, for less. A tsavorite too light or too weak in color is sold as green grossular.
Where is the line? Experts disagree. Some in the trade call any green beryl colored by chromium an emerald; most laboratories and dealers call a stone too light for emerald green beryl, and even they differ on how light is too light. So the name on a listing is the seller’s reading. Check it on an independent laboratory report before you accept an emerald’s price (what an emerald is worth).
“Emerald green” on a listing is a color, not a stone. Synthetic green spinel, for one, is widely used in birthstone jewelry to pass for peridot and tourmaline.

Hello, I am interested in this green stone. Before I choose, could you confirm a few points in writing? 1. If it is an emerald: are its fractures filled with oil or resin, and to what degree? 2. If it is a sapphire: has it been heated, and has it been diffused with beryllium? 3. If it is a tourmaline: has it been heated? 4. If it is jade: is it untreated, bleached and filled with polymer, or dyed? 5. If it is green chalcedony, quartz or topaz: is its color natural, or the result of dyeing, heat or another treatment? 6. If it is a green diamond: is its color natural, from irradiation, or of undetermined origin? 7. If it is a tsavorite or a peridot: can you confirm it is untreated? 8. Will it come with a report from an independent laboratory that names the stone and any treatment? Thank you for your time.
A laboratory report is where this is written down: what a gemstone certificate proves.
