Preparation and Safety Guidelines

Tools Needed
  • 11/6 in metal tube (aluminum or brass)
  • 32 gauge wire
  • Wire strippers
  • Needle-nose pliers
  • Marker
  • Necklace chain (30 in recommended)
Safety Guidelines
  • Always use appropriate safety glasses when working with wire and tools to protect your eyes from potential injury.
  • Be mindful of sharp wire ends. Use pliers to properly cut and shape wire, and carefully handle the finished piece to avoid scratches.
  • If using a soldering iron, ensure adequate ventilation and use a heat-resistant surface to prevent burns and fire hazards.

Step-by-Step Instructions

  1. Prepare the Metal Tubes

    • 1 in, 1 1/2 in, 1 1/4 in, and 1 5/8 in. Write down the measurements to stay organized.
    • Use wire strippers (curved cutting area preferred to avoid crimping) to cut the tubes. Gently round any squished ends with pliers.

  2. Prepare the Wire

    • Cut a 36-inch piece of wire, find the midpoint, and fold it in half.

  3. Start the Diamond Shape (Bottom)

    • Thread a 1-inch piece onto one end of the wire, followed by another 1-inch piece and a 1/2-inch piece on the other end.
    • Thread the folded end of the wire through the 1/2-inch piece, pulling it tight to form a triangle.
    • Continue threading the wire through the remaining pieces in a specific pattern (1/2 in, 1 in, 1/2 in, 1 in, etc.) until only one 1/2-inch piece is left.
    • Thread the last 1/2-inch piece onto the wire, wrap the wire around the corner joint, and thread it back through the 1/2-inch piece. Pull the wire completely through.

  4. Construct the Diamond Shape (Top)

    • For the top, thread a 1/4-inch piece, a 5/8-inch piece, and another 1/4-inch piece onto the remaining wire. Thread this through the next 1/2-inch piece.
    • Repeat the threading pattern until you reach the starting point. Thread the wire up through a 1/4-inch tube.
    • Add and thread 5/8 inch tubes until all pieces are used, creating a diamond shape. Loop the wire through the corner joint and thread it back through the 5/8-inch tube like before.
    • Thread the wire down through the 1/4-inch tube and then the 1-inch tube. Secure the wire by either threading it back through a tube or making a loop for a jump ring.

Tips

  • Use a pipe cutter to cut the tubes if possible to avoid crimping.
  • Use needle-nose pliers to help thread the wire and tighten the joints, especially when the wire gets short.
  • You can adjust the length of the necklace and also create earrings using this same technique.

Common Mistakes to Avoid

1. Uneven Wire Wrapping

Reason: Inconsistent tension while wrapping the wire around the geometric diamond shape can lead to a lopsided or unprofessional-looking pendant.
Solution: Maintain consistent tension and use pliers to ensure tight, even wraps throughout the process.

2. Incorrect Jump Ring Attachment

Reason: Improperly closing or attaching the jump ring to the pendant and chain can lead to the pendant falling off or the jump ring breaking.
Solution: Use pliers to securely close the jump ring, ensuring it's completely closed and lies flat.

3. Improper Measurement of Chain Length

Reason: Cutting the chain to the wrong length results in a necklace that is either too short or too long.
Solution: Accurately measure your desired necklace length before cutting the chain and add extra length for the clasp.
