For this design I wanted to try out a marble effect using a thin brush on uncured gel polish. However I think I got a bit carried away with the amount of lines I had put. I think it would have been better to put a couple of lines per nail and focused on blending them out more. Next time I try this I will have some reference images of marble to hand to help me.
I started by painting all nails with a base coat, curing it, and then curing a coat of white gel polish on top.
On all fingers except the ring and middle fingers I cured a second coat of white. I then brushed on a nail powder over the top of these nails. The powder makes the white look pink and has a teal pearly shimmer effect to it in the light. However the pink was a lot lighter than I was hoping it would be and so there is not much of a contrast between these and the marble nails. Next time I think I would just use a light pink colour underneath to help it a bit.
On the remaining ring and middle fingers I painted another coat of white but I did not cure it. I then took a very thin brush and used a black gel to paint in my marble effect. I painted thin wobbly lines and then went over it with the brush a few times to blend it out more into the white to make it look more marbled. I then cured it.
To finish off the design I used the same thin brush and a metallic pink shade and added little flicks in random places near the lines to add a bit more detail to the marble effect before finishing off with a top coat.
