Natural Line or Crack? 13 Easy Ways to Tell on Jade 🔍
This jade bangle has a very obvious line.
Would you buy it?
Because that line could be a natural internal feature…
or it could be a crack.
So, how can you tell?
Let’s check it together. 👇
1️⃣ LOOK
First, examine the surface carefully.
Does the line actually reach the surface?
If the line appears to stay inside the jade while the surface remains smooth, it may be an internal natural feature.
2️⃣ TOUCH
Gently run your fingernail across the line.
If your nail catches or feels a distinct step at the surface, pay close attention. The feature may be reaching the surface and could be a crack.
3️⃣ LIGHT
Now grab a flashlight. 🔦
But don’t just shine it straight through the bangle.
Move the light from different angles and watch how the line behaves.
If the feature appears to sit inside the stone and changes in appearance as you move the light, it may be an internal feature.
A crack that reaches the surface often appears more like a continuous break through the stone.
But remember:

LIGHT 🔦
And most importantly, don’t assume every line in jade is a crack.
Natural jadeite can contain internal features, textures, and inclusions. At the same time, visual inspection alone cannot always tell you exactly what a line is.
For valuable jade, professional examination is the safest choice.
