First, start off with your base color, this should be a nice ocean blue. I'm Using LA Colors - Aquatic, yea yea yea, with a name like that I had to use it! Here it is with 2 coats.
Next, put your topcoat on your nails, and on your ring finger, while the topcoat is still wet, apply a dark blue heart rhinestone a little over halfway down your nail, then, take your normal rhinestones and from each side of the heart, make them go up like it looks like a necklace. Here are a few pictures of how it should look.
And here is a super close pic!
I hope ya'll like this! It's super simple to do! And looks very pretty! Thanks for reading, until next time! <3
