For my version of the lava mani, I decided to use KleanColor Chunky Holo Scarlet for the red. This polish is fairly sheer, so I started with one coat of Sally Hansen Xtreme Wear Mellow Yellow to give it a bright base. I followed that with two coats of Holo Scarlet, which went on very smoothly. It has a red-orange tinted jelly base, but somehow doesn't seem as gloopy as a lot of other glitter-jelly combos.
I topped it with OPI Black Shatter. Most of the time, I like it that Black Shatter has a thinner consistency and cracks more than some other crackles, but in this case, I was hoping for something that would look more like the skin of cooling rock on top of lava. I was thinking of something more like my Turquoise Stone Mani, so maybe the China Glaze black would be better for this look.
The KleanColor Chunky Holos that I picked up all seem to have the same holo glitter in different colored bases. In a few cases, the base color has enough of an effect to make the glitter look different. Holo Scarlet is one of those; it really makes the glitter look much redder. In this case, it glinted like hotter points in the lava. It didn't pick up well in the photos, but I really enjoyed it.
