OPI- Jade Is The New Black is from the Hong Kong collection for Spring 2010. I had to get it off Ebay as I couldn't see this listed anywhere on the Indian etailer websites. 

Jade Is The New Black is a dusty blue-based green. It's really unique and I don't have anything like it. The soft, muted look makes this green quite wearable.

The formula on this was typical OPI. A little thin, so it took three coats to reach opacity. It applied smootly, without streaking. I didn't need top coat as it was glossy enough on it's own. BUT it chipped within 24 hours :( I will definitely be using a good top coat the next time I wear this polish.
