Zoya Neeka is on my pointer and ring fingers, and Lotus is on the middle and pinky. Neeka is a darker purple and has more shimmer.
In the bottle comparison, you can see that Lotus has pink glassfleck shimmer and Neeka has gold.
The polishes definitely aren't dupes, but maybe sisters. Lotus has a lighter creamier base and pink glassfleck shimmer, compared to Neeka's deeper dustier base and full gold glassfleck shimmer. Lotus is Neeka's happier sister.
Which do you prefer?
