My blue polish is Different Dimension Lapis Lazuli. It's not a true navy blue, I have to admit, but has teal undertones. The jelly base is quite sheer, my pictures show four coats. The polish is filled with multicolored flakies. I added one coat of KBShimmer Clearly On Top for protection and extra shine.
Different Dimension polishes can be found at their own shop and at Hypnotic Polish.
