Pearl Drop is a gold-leaning white shimmer with frosty tendencies. I'm guessing Chanel intended it to be worn sheer, because it took me four coats to achieve something resembling full coverage, and even then I fancy I can still see hints of the yellow staining on my nails (my index and ring fingers are particularly bad right now). In some lighting conditions, the gold sheen is pretty obvious, in others it's more subtle. You may notice bubbling in some of these photos; that's not the polish's fault but rather summer's, as it was super hot and humid the day I did these swatches (outside, as I did not have free run of the house with its wonderful central air conditioning).
Of course Pearl Drop is not the only white with gold shimmer in my stash, so I pulled out some of the others for comparison: OPI Oh So Glam, Zoya Gaia, and Orly Meringue.
The Zoya is the odd polish out here; it's more white than the others and has a scattered flecked gold shimmer that lets the main color show through more. The OPI and Orly are closer to Pearl Drop; neither is a dupe, and I like both of them better than the Chanel. My favorite is the Orly&msdash;it just glows. It also took just three coats; the others are all four.
I thought perhaps Pearl Drop would make a good layering polish, so I tried that next. Here are the base colors I used:
I added two coats of Pearl Drop over the white, nude, and red, but only one over the black because it pretty much covered up the red at two coats; I didn't like that look and didn't want to do the same to the black.
I like Pearl Drop over the white and peach better than I like it on its own, but not enough to think I'm going to want to wear either as a full mani. If I want that look, I'll use a single polish that gets me close (like Oh So Glam, perhaps, or Gaia).
My favorite layering was the single coat over black, especially in lower light levels (last photo below). That I could see myself wearing as a full mani.
I don't exactly regret buying Pearl Drop—I did have fun playing with for this entry, if nothing else—but I don't think it's anything I'd recommend to someone, especially at Chanel prices.
