Green Elbaite is the most common colored variety of the tourmaline group, highly prized for its vibrant spectrum from light mint to deep forest green. Collectors look for well-terminated, striated prismatic crystals often found in pockets within granitic pegmatites. It is easily identified by its distinctive vertically striated crystal faces and lack of cleavage.
Is this green elbaite tourmaline?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch green elbaite tourmaline with a known reference. Green Elbaite Tourmaline sits at Mohs 7-7.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Green Elbaite Tourmaline leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Green Elbaite Tourmaline typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: green, yellow-green, blue-green.
- 5Look at form & habitCrystal system: trigonal. Typical habit: prismatic crystals with rounded triangular cross-section.

Field-hunting tip
Look in granite pegmatites country — that is the host setting where green elbaite tourmaline typically forms. If you start seeing quartz, albite, lepidolite in float, you are in the right ground. Field specimens usually show a prismatic crystals with rounded triangular cross-section habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Maine — start trip planning there.
