Telargpalite is a rare palladium-silver telluride typically found as microscopic grains within massive sulfide ores. It is primarily identified through electron microprobe analysis and reflection microscopy due to its extremely small grain size and scarcity in nature.
Is this telargpalite?
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 telargpalite with a known reference. Telargpalite sits at Mohs 3.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Telargpalite leaves a black streak.
- 3Read the lusterHold the specimen under a strong light. Telargpalite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: steel-gray, silver-white.
- 5Look at form & habitCrystal system: hexagonal. Typical habit: anhedral grains, inclusions.

Field-hunting tip
Look in magmatic sulfide deposits country — that is the host setting where telargpalite typically forms. If you start seeing chalcopyrite, pentlandite, cubanite in float, you are in the right ground. Field specimens usually show a anhedral grains, inclusions habit, so train your eye for that shape before scanning the outcrop.
