Embedding Shells in Resin

Resin is an excellent material for crafters and has a wide range of practical and advanced uses. For our purposes here, we will be using it to make jewelry by embedding shells in resin.

While working with resin isn't terribly complicated, beginners will have an easier time if they start with epoxy resin. Also, it might be helpful to read a little about resin crafts before starting your seashell resin pendant.

Reminder: Make sure you look up any local or state laws and regulations before collecting seashells from the beach.

Supplies to Make a Seashell Resin Pendant

  • Two-part clear epoxy resin kit, such as Envirotext Lite or Castin Craft
  • Plastic resin mold or cast from polymer clay for pendants
  • Mold release spray, such as Castin Crafts mold release for epoxy resin
  • Two craft measuring cups (old medicine cups work well, too)
  • Disposable mixing cups (I use Dixie cups)
  • Toothpicks or disposable crafts sticks
  • Miniature seashells (either plain or colored)
  • Pendant bails (you can use a pinch bail, glue-on bail, or screw-in bail that matches your piece of jewelry)
  • Standard drill with an 1/16" bit (or craft drill that can drill through resin if using a pinch bail)
Seashell jewelry can be made with single shells or several in the same pendant.

Instructions to Make Seashell Resin Jewelry

Once you have your materials assembled, you are ready to begin.

Step 1. Prepare the Mold

  1. If your mold is new, wash it with hot water and soap.
  2. Let it dry.
  3. Spray the mold release product over the entire mold heavily, making sure it gets into every cup.
  4. Let the spray remain on the mold for at least 10 minutes.
  5. Wipe the mold, making sure there is no fluid in the cups.
  6. Place shells, sand dollar, or miniature starfish inside the individual resin cups. (Make sure the fancy side of the shell is facing down as this will be the side that is clearly visible on the outside of your jewelry.)
Miniature seashells come in many shapes and colors.

Step 2. Cast the Resin

  1. Prepare the resin mix according to the package directions.
  2. Use the craft stick to slowly drop the prepared solution into each individual cup to cover the seashells.
  3. Let the solution settle for five minutes (if air bubbles appear you can pop them with the craft stick).
  4. The resin mix will become solid in about 15 minutes. If the seashells rise or turn crooked, it is important to reset them with the craft stick before the solution hardens.
  5. As the resin epoxy solution is curing, do not touch it. Fingerprints and stick marks will be permanently cast into the pendant.
  6. For best results, allow the solution to cure for at least 16 hours before moving it or touching it. When the resin is finished hardening, it will be smooth and dry.

Step 3. Turn the Cast Into Jewelry

  1. It is time to remove the resin seashell pendants from the mold. The best way to get them out without warping your mold for later use is to tap the back of the mold with the handle of a knife until they pop out.
  2. After removal, any uneven edges can be trimmed with scissors. Very jagged edges from overfilling cups can be sanded with fine grit sandpaper. Do not sand the front of the pendant or you will damage the surface and make it cloudy.
  3. Using the power drill, add a tiny hole in the front of the pendant all the way through the piece of resin. Here, you will insert the pinch bail. If you prefer, you can drill a hole into the top of the pendant and insert a screw bail.
  4. Put super glue on the bail tips and slide them into hole. Squeeze them gently with pliers to close the bail. If you do not have a drill, glue-on bails will also work for this project. Carefully glue the bail to the back of the pendant and give it ample time to dry.
  5. When finished, place your pendant on a necklace and enjoy or give as a unique gift.

How to Fix Fingerprints and Other Mistakes in Resin

If you make a mistake in a piece of resin jewelry, such as fingerprints or other indentions, the piece can be recoated and fixed.

  1. Allow the pendant to cure for three days.
  2. Wet sand the entire surface of the piece by hand with fine sandpaper until the flaw is no longer visible.
  3. Allow the piece to dry overnight. It will look very cloudy and sanded.
  4. Apply a thin coat of new resin to the surface very carefully with a small paint brush and allow this to dry for 16 more hours.

Mary on October 15, 2017:

I want to make these for the ladies on my beach retreat. I would like to put a phase on the pendant...can that be done? If so, how? Thank you

Shelly on July 11, 2017:

Just Beautiful!

dougvickie from jefferson city,tn on April 01, 2017:

I'M IN THE PROCESS OF MAKING THIS KIND OF JEWELRY. ALSO USING PETRIFIED WOOD I FOUND ON THE BEACH AND MOUNTAINS.

Pam on June 08, 2015:

When doing these as a teenager, if I got a light fingerprint on the surface, I used to sand with very fine sandpaper and then polish smooth again with Brasso. Does take a while, but much less than 16 hours. Works well to remove scratches from most clear plastics. Really good for cd's or dvd's even clock faces. Hope this helps.

KonaGirl from New York on December 08, 2014:

These look fabulous and your tutorial is clear and concise. I have pinned it to my "DIY Seashell Crafts" board.

Connie120 on April 11, 2013:

Thank you very much!

Tammy (author) from North Carolina on April 10, 2013:

Yes Connie 120. There is a special resin dye sold at craft stores. It usually comes in red, blue and yellow and if you want other colors you must mix them. Anything else other than glitter can make the resin cloudy. I hope you enjoy it!

Connie120 on April 08, 2013:

OK thank you very much. Is there a special dye to use, or can I use a drop of acrylic paint?

Tammy (author) from North Carolina on April 07, 2013:

Great question Connie120. None of these pieces are layered. If you do want to layer resin it is simple enough to do. Just let one coat dry for at least 24 hours, then another coat can be added. It gets really pretty when you are using dye in the resin.

Connie120 on April 07, 2013:

Thank you for really great instructions! I'm looking into using resin for a few projects, and this tutorial will really come in handy. One question, do you make multi-layered projects as well? I was wondering if there would be a line where the layers meet.

Jamie Brock from Texas on November 30, 2012:

Your resin pieces are gorgeous! I love how pretty the sea shells are. Thank you for sharing how you did it :)

Tammy (author) from North Carolina on November 22, 2012:

Thanks for reading Vespawoolf. These pendants are a really great way to make a unique gift. They have been really popular with beach lovers. I appreciate your comment and hope you will give them a try.

Vespa Woolf from Peru, South America on November 21, 2012:

I've never made anything like these pendants before, but your instructions are clear and precise and make me feel like I could do it! I especially like the oblong and teardrop-shaped pendants. I hope to try this as soon as I can get the supplies. Thanks!

Tammy (author) from North Carolina on September 21, 2012:

I have one photo on the hub where it is glued to the back of the pendant. The glue bails aren't made to go on the front. I will check and see what pieces I have left. I hope you will give it a try. Thanks so much for reading and sharing!

Tammy (author) from North Carolina on September 21, 2012:

I am sure they would prettynutjob. This would be a great project for show and tell too. Thanks so much for reading and commenting!

Tammy (author) from North Carolina on September 21, 2012:

I hope you will give it a try Dwachira. It may be the start of a side craft business. :) I appreciate your visit.

Tammy (author) from North Carolina on September 21, 2012:

That is a fantastic idea Tycoon Sam. I think they make punch bowl rings with critters inside of them too. It may give your guests the heebie jeebies, but it would certainly be memorable. Thanks for stopping by!

Tammy (author) from North Carolina on September 21, 2012:

Thanks so much for reading and sharing Peggy W. I appreciate that! :)

RunningDeer from Iowa on September 21, 2012:

This is so COOL! I always come back with tons of shells from the beach and never know what to do with them. So they end up in a drawer. I am definitely doing this. Except, I don't have a drill. Could you possibly post a picture of a necklace that has been glued on from the front? Voted up and shared.

Mary from From the land of Chocolate Chips,and all other things sweet. on September 21, 2012:

This is such a cool idea, I know my kids would enjoy making this little project with me. They have so many shells this would be a much better way of show cases them than the bowl we have them in right now. Voted up, awesome and shared.

Danson Wachira from Nairobi, Kenya on September 21, 2012:

At the coastal town of Mombasa, Kenya i find a lot of seashells. I will remember to grab some the next time i visit and try making this Seashell Resin Jewelry, i looks beautiful and attractive. Voted up and useful.

TycoonSam from Washington, MI on September 20, 2012:

Hello Tammy,

Once again you caught my attention with a great Hub. I don't know if I'll make fancy jewelry like the ones you talked about but I have an idea for some resin ice cubes with flies or spiders in them. Halloween is right around the corner and they might be fun!

Voted up, useful and sharing

Peggy Woods from Houston, Texas on September 20, 2012:

Hi Tammy,

What a terrific idea! Seashells are so beautiful and this is a nice way to show them off by wearing them as jewelry. Beautiful little rocks or other found items could also be preserved and displayed to great advantage with this method. Many up votes and definitely sharing this with others!

Tammy (author) from North Carolina on August 24, 2012:

Thanks Realhousewife. I have seen your patio hub.. you have got some great decorating skills.. lol. If we all lived closer we could have a "jewelry parties" and each time we would make a new craft. Those are so much fun. Thanks so much for reading and commenting.

Kelly Umphenour from St. Louis, MO on August 23, 2012:

Very pretty Tammy! You are so darned crafty - I can't be trusted with any tools such as you have listed. Last time I used a glue gun - I glued stuff to my own thumb:) LOL

I wish you lived near so you could let me watch a few times before I try this a home:) hahaha

Up and excellent!

Tammy (author) from North Carolina on August 20, 2012:

Thanks so much Prasetio. Perhaps I will make one with some of your tiny oragami. That would be neat too!

prasetio30 from malang-indonesia on August 20, 2012:

Very informative hub. I really enjoy this hub so much and your tips are useful for us. I hope I can practice soon. Thanks for writing. Voted up!

Thanks so much pringooals. Thanks for commenting. :)

Tammy (author) from North Carolina on August 19, 2012:

Thanks so much Natashalh. With some practice, resin isn't too bad. It takes a few batches to get good at it and learn when it is "ready" to use. Thanks for reading and commenting!
