Want fashion-forward, but healthy nail polish? Try SpaRitual ($10.00 USD). Their nail laquers are vegan and do not contain DBP, Formaldehyde and Toluene.
These polishes are available in great colors and are very chip resistant. I wore a pretty dark purple (Regal) all last week and they only started chipping toward the end of the week.
The Forbidden Collection contains the following shades:
Regal — dark purple creme
Intrigue — tomato red creme, lots of orange in it
Mystic — mushroom, taupey creme
Inner Sanctum –light peach brown creme
Hush — warm chocolate creme
Hypnotic — warm charcoal frost
This is their Fall 2009 collection, but the colors are cool enough to wear all year round. I love dark colors for everyday wear.

Have you ever tried China Glaze products? They do very good colours and they actually do not chip after 24 hrs.
