Sephora Diamond Eyeliner ($14.00 for 0.0176 oz.) is a range that features black-based eyeliners with “ultra-reflective pearls” that are layered on top of a deep black. There are six shades in the range. It is a twist-up, very creamy, soft eyeliner that glides across the skin effortlessly and takes about thirty seconds to set. The wear ranged from eight to nine hours on the lower lash line for me.

Sephora Canary Diamond Eyeliner ($14.00 for 0.0176 oz.) is a blackened brown base with flecks of olive gold pearl and micro-sparkle. It had good color payoff in a single stroke, and the creamy consistency made it apply and layer well with no skipping or patchiness. It lasted for eight hours on me. MAC Black Line (P, $15.00) is less shimmery (95% similar). See comparison swatches / view dupes side-by-side.

Sephora Cushion Cut Diamond Eyeliner ($14.00 for 0.0176 oz.) is a cool-toned black base with lighter silver sparkle and a soft sheen.
