Gather your stones and wash them. Let them dry.
Choose your color and start painting all over the stones.
Then put glitter on them before they dry. Use the same gliter as your stone color. Black glitter on black stone, pink on ponk, blue on blue and so and so
Ta da... Here is the result. I have got 4-5 different color so i can use them in different area in my house.
