I used 2 coats of polish for every swatch shown..
Moonstone is a beautiful Opal. It doesn't really have a color "shift" it's more iridescent so you see hints of blue and pink coming through the white base. This is not a sheer polish and was opaque in 2 coats.
Chanel Peridot dupe, however, the main color of this is a warm gold not green.
Do you hear the angels singing? If not you need you hearing checked because this color is a bottle of awesomesauce! Lava is an reddish orange flakie with a yellow color shift. Yes a duochrome flakie, nothing gets more awesome than that!
Scarab is a beautiful teal. The color shift in this one, like ChG Deviantly Daring, is very minimal. It does have an ever so subtle shift from blue to teal but let's face it, it's teal.
Now here's some comparisons...
SH Moonstone vs Pixi Opal Sheen
I almost didn't compare these because they looked so different in the bottle(Opal Sheen has a strong pink undertone whereas Moonstone is more blue/pink iridescent). Yet they photographed very similar, although you can see that Opal Sheen is far more pink. The only big difference is Moonstone has a frosty appearance where Opal Sheen is very smooth.
If you recently picked up the new Maybelline Color Show polish in Downtown Brown and thought that Copperhead looked like it, think again. Even though I swatched using MAC Blue Brown pigment it's very similar to Downtown Brown (MAC Blue Brown pigment is more of a redder brown). While Copperhead has the red brown thing going on it doesn't have a blue shift, instead it has subtle gold shimmer.
Overall: These had a great formula, not thick or brushstrokey. They applied smooth and even and are very pigmented! You only need 2 coats to achieve full color opacity. They have an average dry time only if applied in thin layers, If you apply too thick they seem to never dry. I applied each color over WnW Black creme so you could see the duochrome color and I also applied a matte topcoat. Unfortunately the matte top coat did nothing but dull it so I'll have to experiment more with that.
Price: I bought these for $8.99 a piece at Walgreens, but Walgreens prices are always high(to me at least). I think when these come to places like Walmart they may be a couple dollars cheaper. Bu for now if you could only get a couple from this collection I would say the must haves are definitely Lava followed by either Copperhead or Firefly.
Hope you enjoyed and happy shopping! ;)
