NARS Corsica Lipgloss ($26.00 for 0.18 fl. oz.) is described as a "shimmering pink raspberry." It's a rosy plum with warm undertones and a very fine, gold shimmer. It had mostly opaque color coverage with a lightweight, comfortable feel on the lips that was somewhat sticky. The color wore well for five hours and was moderately moisturizing. I found this shade hard to dupe due to the more opaque color. MAC Seeking Adoration (LE, $20.00) is cooler, sheerer. Revlon Pinkissimo (P, $7.99) is lighter. Dior Dolly Pink (453) (P, $29.50) is lighter. See comparison swatches / view dupes.
