In another container, mix the essential oils with the melted coconut oil.

Very slowly, combine the oils with the dry mixture. If you pour in the oil too quickly, the citric acid will begin to react and start bubbling.

Keep stirring in the oils until you have a thick mixture.

Step 2: Coloring the Mixture

Use food coloring to give your gemstones a fun pop of color. Spoon small amounts of the mixture into separate bowls, and then add a few drops of color. Mix well until the mixture is all the same hue.

Step 3: Create the Gemstones

Roughly mix together small amounts of each color in a clean bowl without pressing them together. The mixture should now have a crumbly consistency.

Push the mixture into the bottom of the mold, filling it up to the top line. Use the back of the spoon to pack it in as tightly as possible. Do the same with the lid of the gemstone mold.

Line up the top and bottom mold and push together. Any excess bath bomb mixture should squeeze out the top. Wipe this away until the surface is smooth.

Keep the mold in the fridge over night. Once the mixture is set, peel the bottom piece of the mold off. Carefully remove the top half of the mold. Using your fingers, brush off the excess from the sides and the top.
