Jade is another Brazilian brand that has incredibly strong holos in their line and I am ALL about the holos :)
This one is the most brilliant gold color - it's that stunning honey, gold bar gold with a super strong linear rainbow holo.
This was actually fairly opaque so it would've been fine with just 2 coats. If you layer one coat of this polish over another gold you can still see the other polish underneath with the awesome holo on top. I did that with OPI's Goldeneye and had that as my manicure for when I saw Skyfall (which I loved).
Mystic Gold is $7 and can be purchased on Llarowe, which is an online etailer that sels multiple indie and international brands.
