Telluronevskite is an extremely rare lead-bismuth telluride mineral that typically occurs as anhedral grains within hydrothermal quartz veins. It is most easily identified by its metallic lead-gray luster and perfect basal cleavage, though microscopic analysis is usually required for definitive identification.

Is this telluronevskite?

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 telluronevskite with a known reference. Telluronevskite sits at Mohs 2-3 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Telluronevskite leaves a black streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Telluronevskite typically shows a metallic luster.
  • 4
    Match the color range
    Compare against the expected color range: lead-gray, silver-white.
  • 5
    Look at form & habit
    Crystal system: trigonal. Typical habit: massive, anhedral grains.

Where rockhounds find telluronevskite

Classic worldwide localities

  • Nevskoye deposit, Magadan Oblast, Russia

Field-hunting tip

Look in hydrothermal veins country — that is the host setting where telluronevskite typically forms. If you start seeing galena, bismuthinite, quartz in float, you are in the right ground. Field specimens usually show a massive, anhedral grains habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify telluronevskite?+
Mohs hardness is 2-3. It typically shows a metallic luster. The streak is black. Common colors include lead-gray, silver-white.
Where is telluronevskite found?+
Notable localities include Nevskoye deposit, Magadan Oblast, Russia.
How much is telluronevskite worth?+
Typical asking prices fall in the range of $50-300 per specimen depending on size and rarity. Quality, size, and provenance can move individual specimens well outside that range.
Is telluronevskite safe to handle?+
It contains toxic constituents. Contains lead and tellurium; handle with care to avoid inhalation of dust or ingestion. Wash hands thoroughly after handling specimens. Handle with care, avoid grinding or breathing dust, and store separately.
What rocks look like telluronevskite?+
Telluronevskite is most often confused with Galena, Tetradymite. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with telluronevskite?+
Telluronevskite commonly co-occurs with Galena, Bismuthinite, Quartz, Gold. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does telluronevskite form in?+
Telluronevskite typically forms in hydrothermal veins. Working float back to the host body is the standard way to chase a fresh occurrence.
What is telluronevskite used for?+
Telluronevskite is used in collector.
