don’t know much about pressure treatment
Pressure treatment in Amber, combined with heat, turns an Amber that is quite cloudy into a clearer stone.
However, the treatment also darkens the stone - which gives it the 'Cognac' colour that they describe. Before heat and pressure treatment, the Amber likely started out as a more yellow or golden colour, rather than the deep Orange / Brownish-Orange we see on screen.
I think it's an acceptable treatment for jewellery stones - but if I was a collector, I'd want it in its untreated form.
