For a newer favorite, I thought that OPI Muir Muir On The Wall from the 2013 San Francisco Collection was just too beautiful to pass up. It's a charcoal black base with green, copper and burgundy shift - I had not really seen anything like it before and it really reminds me of the changing foliage in the fall. Unfortunately, the multichrome effect is not as strong on the nails as it is in the bottle and the formula is a bit on the thin side, but ultimately still worth it in my opinion.
Jem was the first nail polish from Zoya that absolutely stole my heart: I ogled swatches online for a good couple months before finally deciding to pull the trigger. Jem is a dark plum base with copper and gold foil - the shimmer particles are bigger than those of OPI Muir Muir On The Wall. It looks absolutely stunning in the bottle, but again, the beautiful shimmer is much subtler on the nail than in the bottle, and there's not much shift between gold and copper. But, the delicate foil gives Jem some depth and I still find myself reaching for this shade again and again. The formula is easy to work with but not as long-wearing as the OPI shades.
