Lab-grown amethyst is made in huge quantities and is very hard to tell from natural by eye. For a fine jamunia, an independent lab report is the dependable way to be sure it is natural.

What a lab looks at in amethyst

Natural or lab-grown: hydrothermal synthetic quartz is picked out from twinning patterns under polarised light and from infrared spectroscopy.
Heating: heat turns amethyst yellow, and it is then sold as citrine; for golden stones the lab can comment on this.
Dye: crackled quartz dyed purple turns up, mostly as beads.
Look-alikes: purple glass and purple sapphire are separated by refractive index.

You can do the same with citrine, purple sapphire and kunzite. There is more on our lab-certified gemstones page.
