Method 1
Inner laser (sub-surface 3D etching)
- Surfaces
- Crystal — both optical crystal and crystal glass
- Appearance
- Frosty white 3D dots etched inside the crystal block. Reads from any angle. Does not show colour.
- Best for
- Recipient names, citation copy, company logos in mono. Senior-tier corporate recognition where the engraving needs to feel substantial.
- Cannot do
- Cannot reproduce colour or photo logos. Cannot etch deeper than the crystal's internal layer permits.
