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 check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

1
Test the hardness
Try to scratch spryite with a known reference. Spryite sits at Mohs 2.5 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Spryite leaves a pale yellow streak.
3
Read the luster
Hold the specimen under a strong light. Spryite typically shows a adamantine luster.
4
Match the color range
Compare against the expected color range: yellow, yellowish-orange.
5
Look at form & habit
Crystal system: orthorhombic. Typical habit: tabular crystals, crusts.

Where rockhounds find spryite

Classic worldwide localities

Tetiuhe, Primorsky Krai, Russia

Field-hunting tip

Look in hydrothermal polymetallic deposits country — that is 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.

Common questions
