How do I work with agate?

Agate

  • Hardness: 6-7Mohrs
  • Specific Gravity: 2.6
  • Refractive Index: 1.53-1.54
  • Crystal System: Triagonal
  • Chemical Composition: Silicon Dioxide

Working with Agate

Agate is a relatively durable material and is resistant to most chemicals. However, some banded agate could separate along the layers within the stone if enough pressure is applied, so care should be taken when handling and during setting.

Treatments

Agate is frequently dyed to enhance or change its body colour completely. The absorption of the dye depends on the degree of porosity of the different layers within the agate.
