Forum Thread: Crystal Engraving

Hi there

I am looking for any info on how this crystal pendant was made. The description says it was 'flower of life deep burned into the crystal'. Does anyone have any idea about this process?

Or would it be possible to make it with a dremel? Raw crystals are not always flat surfaces so would it be possible? And how can it be so precise and samll?

Any help is very appreciated!
Thanks!
