Setting a boulder opal into a pendant necklace is a beautiful way to showcase the mesmerizing colors and patterns of this unique gemstone. Boulder opals, known for their stunning play of colors and the way they naturally form within ironstone, make for captivating jewelry pieces. In this blog post, we will guide you through the process of setting a boulder opal into a pendant necklace, turning it into a wearable work of art.

Step 1: Gather Your Materials

Before you start, ensure you have all the necessary materials on hand. You’ll need the following:

  • Boulder Opal: Choose a boulder opal from our website that speaks to you in terms of color and pattern. They come in various shapes and sizes, so consider what suits your design.
  • Pendant Setting: Select a pendant setting that complements your opal. Common choices include bezel settings, prong settings, or wire-wrapping. You may also choose to drill the opal. We recommend only using a laser drill after an opal has been finished with its final polish to avoid blow outs.
  • Chain or Cord: Decide on the type of necklace chain or cord you want to use. It should match the style and design you have in mind.
  • Jewelry Tools: Invest in basic jewelry-making tools like pliers, wire cutters, and a jeweler’s saw, depending on your chosen setting.
  • Adhesive: You may need jewelry adhesive or epoxy to secure the opal into the pendant setting. This is up to the jeweler as some people do not do this and rely soly on the setting to secure the opal in its place.

Step 2: Design Your Pendant

Plan your pendant design. Decide whether you want the opal to be the focal point or if you’d like to incorporate other gemstones or elements into the necklace. Sketch out your design to visualize how everything will come together.

Step 3: Prepare the Opal

Handle the boulder opal with care, as it can be fragile. Clean the opal gently using a soft cloth. If the opal is dirty or not pre polished / in rough or rubbed form then you may want to use some water to remove any dirt or oil. Dry it thoroughly before proceeding to work with the opal.

Step 4: Select and Prepare the Setting

Choose the pendant setting that best suits your opal and design. Bezel settings are a popular choice for boulder opals, as they offer protection and secure the gemstone in place. Ensure the setting is clean and free of any debris or residue.

Step 5: Set the Opal

If you’re using a bezel setting, carefully place the opal inside it. Make sure it’s centered and secure. You can use jewelry adhesive or epoxy to bond the opal to the setting, but be cautious not to use too much, as it could affect the opal in some cases.

Step 6: Secure the Opal

If you’re using prong settings, gently bend the prongs over the opal to hold it securely in place. Be careful not to apply too much pressure, as boulder opals can be delicate.

Step 7: Assemble the Necklace

Attach the pendant to your chosen chain or cord using jump rings or wire-wrapping techniques. Ensure the pendant is centered and secure on the necklace.

Step 8: Finishing Touches

Once your pendant necklace is assembled, inspect it for any imperfections or loose elements. Make any necessary adjustments and ensure everything is polished and clean.

Setting a boulder opal into a pendant necklace is a creative and rewarding jewelry-making project. The final result will be a stunning piece of wearable art that showcases the natural beauty of this unique gemstone. Whether you’re crafting it for yourself or as a gift, a boulder opal pendant necklace is sure to be cherished for its captivating colors and intricate patterns. Enjoy the process of creating your own masterpiece, or trust in a qualified experienced jeweler to do it for you.
