Typical microscopy/photography techniques explained

• Darkfield illumination — highlights small opaque or transparent inclusions
• Brightfield transmitted light — shows internal features in transparent stones
• Reflected light — useful for opaque inclusions and surface features
• Immersion microscopy — reduces surface refraction for clearer internal images
• Polarized light and conoscopic observation — for optic sign and strain
