Spryite is an extremely rare silver-antimony oxide mineral typically found in complex hydrothermal ore deposits. It is known for its distinct yellowish tabular crystals and is primarily a prize for advanced mineralogists and systematic collectors.
Is this spryite?
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 spryite with a known reference. Spryite sits at Mohs 2.5, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Spryite leaves a pale yellow streak.
- 3Read the lusterHold the specimen under a strong light. Spryite typically shows a adamantine luster.
- 4Match the color rangeCompare against the expected color range: yellow, yellowish-orange.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: tabular crystals, crusts.

Field-hunting tip
Look in hydrothermal polymetallic deposits country, the host setting where spryite typically forms. If you start seeing galena, sphalerite, pyrite in float, you are in the right ground. Field specimens usually show a tabular crystals, crusts habit, so train your eye for that shape before scanning the outcrop.
