Here is part of a Live Chat were I asked how to dupe Metal Rock, Gold Deposit, and So Ceylon. Hope it helps.
Jessica : I was also wondering if there was a way to recreate to the look and finish of Metal Rock Mineralize Skin Finish
Jessica : I was thinking about using Sweet As Cocoa and paring it with a pigment but am not sure how that will work out...
Jen: Yes, I recommend Chocolate Brown Pigment, for a shade similar.
Jessica : Alone?
Jen: Yes, the Chocolate Brown Pigment is a similar comparison to the Metal Rock Mineralize Skinfinish.
Jessica : And for Gold Deposit - should I just use Amber Lights?
Jessica : or is there a pigment that will mimic it better?
Jen: I recommend Golden Bronze Iridescent Powder, for a shade similar to Gold Deposit MSF.
Jessica : And for So Ceylon? Sorry for all of the questions, but I missed these when they were originally released
Jen: Copper Sparkle Pigment.
