Orly Taffy and CND Pink Chrome. Terrible picture but it was the only one that showed the shimmer. Taffy is a bit more on the peach side.
Essie Skin Deep and CND Love Struck. This Essie is my favorite, the CND has bit silver sparkles.
China Glaze Sex on the Beach and OPI Sweet Love at Ferris Wheel. I always thought the OPI was more peachy but I guess I was wrong. Under this lighting the two are pretty much identical. The OPI is also said to be a dupe of OPI Beachen Peachen.
China Glaze Pink Rox-E and OPI Chaple of Love. Pink Rox-E's sparkles are a bit larger and more pronounced.
OPI Passion for NY Fashion and CND Scorch. Some would argue that PfNYF doesn't have a dupe but this CND comes close in my opinion.
Pue Ice Iced Merlot and Urban Decay Big Bang. Not dead on dupes but similar, the Pure Ice can be found at Walmart, the UD is long gone.
