DIY Gemstone Soap

Gemstone Cover Photo Book Font.jpg

I don’t know what got into me this morning, but I signed up for six webinars that I saw on Facebook, listened to three of them, created this blog, made these soaps, and wrote this post. And I didn’t even have coffee this morning! Ha.

It has been rainy here in California for weeks and weeks, so instead of exploring outside and hiking, I’ve been inside organizing my crafting supplies. We just moved recently (like… two weeks ago recently), so we have a second bedroom now that is functioning as an office/craft room. SO EXCITING! What are your favorite organization tips for your craft supplies? I love labels and containers. The Container Store is my all-time favorite store. I have so many containers that I don’t have enough stuff to put in them. Haha. Do you like carts? Boxes? Help!

On Saturdays, the mail comes EARLY, so a wonderful Amazon package arrived at my door around 10 am, containing “food coloring” for soap and bath supplies. I decided to try my hand at some pretty gemstone soaps. I was planning to just add this as a product to my website, but then decided I also wanted to share this as a tutorial with you! This would be an excellent craft for a girls’ night (paired with wine, while watching The Bachelor), or a mother/daughter weekend activity, or something just for you to do when you need to de-stress. There’s nothing like mixing fun colors and coming away with a product you can use for yourself or for a gift.

Click on any of the following photos for more information on the items I used:

Here’s what you’ll need: 

-1lb glycerin melt and pour soap base
-Soap-making liquid color (don’t want to dye the tub!)
-Plastic cups (5 oz)
-Stainless steel pitcher
-Wooden disposable spoon for mixing your colors
-Fragrance oils or essential oils
-Large bowl
-A fan OR airtight container with silica packets


  1. Boil a large pot of water on the stove.
  2. Chop up your glycerin into 1-inch cubes and place in stainless steel pitcher (or however else you’d like to double-boil. I recommending having a separate vessel for crafting that you don’t use for food, though). Set in the boiling water. I actually skipped the chopping step, which is fine, but it takes a lot longer to melt.
  3. Wait for the glycerin to melt completely. Prepare an ice bath in a large bowl.
  4. Set out enough plastic cups for the amount of different colored “mini gemstones” you’ll want inside your soap (I would do a minimum of three, maximum of ten if you want to do a rainbow).
  5. Pour a small amount of melted glycerin into each cup, so it’s about 1-1.5 inches full.If your stove was on higher than 1-2 for the double boiler, you might want to take the glycerin off the stove for a few minutes before pouring (we are working with plastic, here, people). (: I only warped one cup when I did this. Haha! You also want about 2/3 of the glycerin left in the double boiler (melted) for later.
  6. Now, start mixing your colors into the cups of glycerin! One drop of coloring is fairly light. For my darkest colors, I used three drops. You can also take a toothpick and just put a very small amount of color into the cup to make a super lighter shade. Now is the time to decide if you want a rainbow, cool tones only, warm tones only, or gradients of one single color. Stir with your wooden spoon to mix.
  7. Once you’re satisfied with your colors, place the cups into the ice bath for 20 minutes to harden OR just leave them out on the counter for about an hour.
  8. Once they’re hardened completely, pop the colored soaps out of the cups carefully. If you can’t pop them, you can a slit down the cup with scissors and peel the cup away. If you CAN pop them out, though, you can reuse the cups in step 10.
  9. Chop each color up into small slices or cubes.
  10. Fill the same plastic cups (or new ones if you had to cut them) about 1/3 – 1/2 full with the hardened colored soap cubes. Be creative here. I think it looks nice to do cool tones together and warm tones separately, but you can really do anything you want.
  11. Turn your burner off. Add your essential oil or fragrance to the glycerin left in the double boiler. I only had to add about 4 drops for my soap to smell fragrant, but I would add more if you’re using essential oils. Just go drop-by-drop and smell.
  12. Now, pour the still-melted leftover glycerin into the cups until all the colored soap cubes are covered. You can also stop short of covering the cubes for a fun, jagged effect.
  13. Place the cups back in the ice bath, adding more ice if needed. Let them harden completely (another 20 minutes). Be careful not to let them tip or get water in the cups when they’re in the ice bath. I tried that and it did NOT work well. Suds everywhere.
  14. Pop your (almost) finished product out of the cups.
  15. Grab your knife and start creating facets and sides to your gemstone! You can cut the soaps in half and make two smaller soaps from the one plastic cup (this is what I did), leave them as one large piece of soap, or even cut them into 4-5 smaller pieces for small gemstones (this is what I did with the solid peach-colored ones shown below). If you need inspiration, check out some photos of crystals for how to slice your “gemstone.”
  16. Set your soap in front of a fan for 1-2 hours, especially if you live in a humid environment or have humidity in your home. Glycerin soaps can look “sweaty” after they dry, which is just little beads of moisture. If you KNOW you’ll be making them in a humid environment, you may want to place your soaps in an airtight container with silica packets at the bottom right after popping them out of the molds – for about 30-45 minutes. Don’t leave them in there too long, or they’ll dry out!


You did it! Let me know if you tried this, or plan to try it. You might have enough of the items at home (spoons, pot for double boiling, essential oils), so hopefully you can make it work!

If you don’t feel like making these, I’ll be selling gemstone soaps soon on my website, along with bath bombs, cold process soaps, jewelry, salt soaks, and more.

In the comments, tell me your FAVORITE soap scent. Right now, mine is rose. I want to hear yours!
