We're Nuts for Acorn Resin Jewelry!

When it comes to crafting, the ability to transform everyday items and shapes into artistic marvels can result in some beautiful and unique wearable masterpieces. Masterpieces like today’s project: acorn resin jewelry. Specifically, acorn necklaces.

These little fellas are familiar to most of us, but with fall on the horizon, you might start to see them scattered around more. Autumn serves as our inspiration for this tutorial, in which we’ll discuss molding and casting a basic shape to help create your own acorn necklace.

If you'd like, you can follow along with our quick video: 

What You’ll Need:

Supplies needed to make a resin acorn necklace.

Make Your Own Resin Acorn Necklace

To be able to create replicas out of the acorn kernel (or nut), you’ll need to create a mold. Pre-made acorn molds are available for purchase, but, with a little extra effort, you’ll be able to make exactly what you’re looking for.

Creating a Custom Mold for the Acorn Kernel

Products like Mold Putty from Alumilite are an easy way to make basic custom molds, especially for small shapes like an acorn. This silicone putty comes in two parts that are different colors.

Take a piece of the yellow and the white putty (enough that, when combined, will cover the object you’re making a mold of). Fold the two parts together until they become a uniform color.

Press the acorn into the putty to create the beginnings of an impression. Fold the putty up around the edges of the acorn to make a mold of the entire acorn kernel. Leave the very top of the acorn, or the cap, uncovered.

After 20 minutes, the mold putty will be cured, and you can remove the acorn. What’s left will be a sturdy mold which you can use to make multiple castings.

Mixing, Adding, and Pouring

We chose to encapsulate some dried foliage in our acorn necklace. Since there’s not a lot of space to work with in the mold, we trimmed down pieces of our dried plants. Check that the piece you snipped off fits in the mold before setting it aside. For your necklace, you’ll want to double check that the piece(s) you’ve picked fit in the mold before setting them inside.

As a reminder, if you plan on using foliage or similar organic material in a resin craft, they work best when they’re dried. You can purchase packs of pre-dried flowers and plants online or at your local craft stores or you can dry them yourself.

Now it’s time to measure out and mix up the ProMarine Supplies Table Top Epoxy Resin. Since we’re casting something small, we won’t need a lot. Just make sure to read the instructions prior to use. Start by measuring out equal parts A and B before mixing them together.

Next, we’re going to add the glitter to our resin mixture. When it comes to incorporating additives like powders, glitters, and dyes, remember that a little goes a long way; you can always add more later on.

Pour in your glitter and mix it so that it’s evenly distributed.

Now, carefully pour the resin and glitter mixture into your custom mold. Afterward, use craft tweezers to place the small foliage pieces in the resin.

Once that’s all set, let the resin do its thing. Leave it to cure for 24 hours in an environment with a temperature of around 75 to 80 degrees Fahrenheit. After 24 hours, you can remove the cured resin from the mold.

Assembling Your Acorn Necklace

To assemble the acorn pendant, take the cap from a dissembled acorn and check that it fits on top of the piece you’ve cast. Use an adhesive to glue the cap to your resin acorn. Hold the cap in place and allow time for the adhesive to dry.

Once the acorn pendant is glued together, you’ll need to drill two holes into the cap using a drill and a small bit. These holes will be used for the necklace cord so make sure they’re big enough to fit the one you’ve chosen.

Once you’ve drilled the holes, use pliers or tweezers to carefully thread the cord through.

Once everything is dried and assembled, your acorn necklace is ready to wear, sell, or gift! Here’s how ours turned out:
