Interestingly, these are some of my hardiest plants. I've spent hours online trying to find out what they are... and yet they have remained unidentified.

#1 had brass coloured leaves when I first got them then later on displayed pearlescent hues of green, pink, purple.

#2 had coppery purple leaves at one point but now has pinkish/ purplish tinges. It grows faster than other echeveria I have and offshoots freely.

Both are more greenish now as we haven't had much sun.
