Eztlite is an extremely rare lead-zinc tellurite mineral discovered in the oxidized zones of Mexican tellurium deposits. Collectors typically look for its distinct pale yellow, platy crystals that form in association with other rare secondary tellurium minerals.

Is this eztlite?

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 eztlite with a known reference. Eztlite sits at Mohs 1-2 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Eztlite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Eztlite typically shows a pearly luster.
4
Match the color range
Compare against the expected color range: pale yellow, yellowish white.
5
Look at form & habit
Crystal system: monoclinic. Typical habit: platy crystals, fine-grained aggregates.

Where rockhounds find eztlite

Classic worldwide localities

Moctezuma mine, Sonora, Mexico

Field-hunting tip

Look in oxidized hydrothermal tellurium-bearing deposits country — that is the host setting where eztlite typically forms. If you start seeing tellurite, paratellurite, mcalpineite in float, you are in the right ground. Field specimens usually show a platy crystals, fine-grained aggregates habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify eztlite?+

Mohs hardness is 1-2. It typically shows a pearly luster. The streak is white. Common colors include pale yellow, yellowish white.

Where is eztlite found?+

Notable localities include Moctezuma mine, Sonora, Mexico.
