Laura Mercier Nail Lacquer "Twilight"

Twilight is part of Laura Mercier's Limited Edition Moonlight Collection.  It is a reddish purple, with purple sparkles and an occasional red flash.  It's a beautiful polish.  That said, it is very much like Chanel Paradoxal as you can see from the comparison swatches.  Paradoxal is much more sophisticated; when applied, a smoky gray veil subdues even the further its subtle purple shimmer. 

Paradoxal only requires one coat to fully cover the nail bed, while Twilight is thin and requires two coats for even coverage.  Actually, three coats are better. 
Most critically, Twilight doesn't wear well.  I wore it for a week with my usual Lippmann Rehydrating Base Coat and Seche Vite Dry Fast Top Coat.  I re-applied with CND Stickey Base Coat and Seche Vite Dry Fast Top Coat.  This is how the tips look after two days.

Chanel doesn't look this worn after a week.  Paradoxal is still available on Chanel.com and at Nordstrom.  Twilight is limited edition and available at Nordstrom and LauraMercier.com.  Let me now if you've had better luck with it.
