Handmade Jewelry Using Resin Molds: Dramatic Pendants and More

Resin cast in detailed jewelry molds creates glossy, dimensional pendants, rings, and components. Combined with inclusions like dried flowers or glitter, resin takes on an artistic fluidity perfect for jewelry.

This guide covers selecting and using silicone molds to handcraft resin jewelry. Learn techniques from preventing bubbles to layering colors. Find inspiration in creative ways to transform resin and molds into one-of-a-kind art jewelry pieces.

Benefits of Using Resin Molds for Jewelry

Resin molds provide many advantages for jewelry making:

Selecting Resin Jewelry Molds

Many materials work for resin molds depending on the project:

Silicone – Flexible with fine detailing. Easy release. Ideal for intense detail like filigree. Can gently bend silicone into dome shapes.

Plastic – Affordable and accessible. Limited fine detail. Rigid shapes only.

Glass or Acrylic – Very rigid but suited to flat backings. Creates clear see-through layers.

Wood – Best for simple rustic shapes. Resin can stick to porous material.

Metal – Like brass filigree charms. Resin won’t bond to metal. Avoid highly intricate open designs that trap resin.

Helpful Supplies for Resin Jewelry Molding

Beyond quality molds and resin, a few additional supplies prove useful:

  • Mixing Containers – Disposable plastic cups or resin mixing pots
  • Stir Sticks – Disposable popsicle sticks, stir sticks, or micro spatulas for mixing resin
  • Dropper – For adding resin tints and inks dropwise
  • Propane Torch – Helps pop air bubbles in resin before hardening
  • Rubber Bands – Secure pieces around curved molds to prevent leaks
  • Vaseline – Lubricates molds to prevent sticking
  • Sandpaper – Fine grit removes any raised seam lines after unmolding pieces
  • Sealant – Polyurethane, spray sealer, and resin sealants protect finishes

Step-by-Step Guide to Resin Jewelry Molding

Follow this general process for flawless cast resin jewelry results:

Step 1 – Select Mold Design

Choose mold shapes and details suited to the jewelry piece. Opt for molds that can embed inclusions.

Step 2 – Clean and Prepare Mold

Wash molds in mild soap and water. Dry fully. Apply Vaseline mold release if needed.

Step 3 – Plan Inclusions

Gather dried flowers, photos, confetti, glitter or any embellishments to encase in the resin.

Step 4 – Calculate Resin Amounts

Determine how much mixed resin is required to fill the mold cavity volume fully.

Step 5 – Mix Resin

Combine resin and hardener according to packaging directions. Stir thoroughly 3-5 minutes until fully blended.

Step 6 – Pour Resin

Slowly fill mold fully from one corner to prevent air bubbles. Tap mold to help bubbles rise.

Step 7 – Release Air Pockets

Use propane torch to lightly pass over resin and help stubborn bubbles pop. Avoid direct contact.

Step 8 – Seal Mold

If needed, secure a top around mold walls with rubber bands to contain resin while curing.

Step 9 – Allow Resin to Set

Leave cast resin undisturbed to harden fully before unmolding according to resin directions.

Step 10 – Unmold Carefully

Gently flex and work mold to pop out finished resin piece. Avoid damaging intricate details.

Step 11 – Finish Edges

File or sand any rough mold seam lines until smooth. Polish with microfiber cloth.

Step 12 – Apply Protective Sealant

Finish resin surface with clear acrylic spray or other sealant for shine and scratch protection.

Helpful Techniques for Dazzling Resin Jewelry Molds

Take cast resin jewelry to the next level using these specialized molding techniques:

Doming Molds

Turn flat molds into dome shapes by heating in hot water then bending gently before pouring in resin. Creates dimensional cabochons.

Section Molds

Divide deep molds like spheres into upper and lower pieces for easier filling. Join halves later to encase inner contents.

Embedded Objects

Press meaningful items like coins or photos into resin before hardening to encapsulate them. Makes sentimental jewelry.

Geode Molds

Coat crystalline mold interiors with clear resin tinted with alcohol ink or mica powder swirls. Creates “sliced” agate effects.

Powder Coating

Sprinkle metal powder, mica, or flocking powder into mold to coat embedded items with a business, sparkly, or velvet touch.

Backfill Clear Resin

Pour a thin transparent layer to encase contents fully, then let cure before filling remainder of mold for crystal clarity.

Staged Layering

Pour colored layers in intervals, allowing each to partially set before adding the next hue. Creates artful color gradients.

Silicone Molding

Press finished resin pieces into silicone to capture shape. Reproduce textured focal beads, cameos, or custom components.

Inspiring Jewelry Projects Using Resin Molds

Looking for ideas to fire up your mold-based jewelry creativity? Here are beautiful possibilities:

Pressed Flower Jewelry

Encapsulate delicate flower petals, leaves, and stems in clear resin pendants and paperweights to create a lasting bouquet.

Photo Jewelry

Capture cherished moments by pressing photos into dimensional resin like domes or cubes. Makes sentimental pendants and keychains.

Mystical Symbol Jewelry

Cast astrological, alchemical, sacred geometry, and ancient icon molds in gold-tinted resin as otherworldly pendants.

Statement Rings

Pour vibrant resin into bold ring molds shaped like flowers, skulls, animals, or feathers for standout molded rings.

Glitter Dome Jewelry

Mix ultra fine glitter into clear resin and pour into half sphere molds. Glitter floats and shimmers within these dimensional pendants.

Souvenir Jewelry

Press tickets, coins, or shards of fabric into resin to encapsulate memories and events in lucite jewelry keepsakes.

Bezel Pendants

Fill bezel tray molds with resin tinted and swirled like gemstones. The frames become dazzling dimensional resin “cabs”.

Ocean Resin Jewelry

Tint clear resin with blue alcohol ink. Add bits of sea glass, sand, shells, and glitter captured in wave or octopus molds for oceanic designs.

Troubleshooting Common Resin Molding Problems

Don’t worry, resin molding has a learning curve. Here are solutions to common issues:

Bubbles in Resin – Use a propane torch briefly on the surface to help bubbles rise and pop or pour in very thin layers, waiting for each to cure before adding more on top.

Resin Not Curing – Ensure equal resin and hardener are mixed thoroughly. Not mixing for the full recommended time prevents hardening. Also check for expired products.

Mold Sticking to Resin – Give resin adequate time to cure fully before unmolding to avoid it adhering. Apply petroleum jelly or silicone spray to mold interior as an extra release barrier.

White Spots on Resin – Dry powder pigments clump up when mixed directly into resin. Instead premix powdered tints into a small amount of clear resin before adding to make an even colored resin base.

Resin Cracked or CrazedCooling resin too quickly creates internal stresses that manifest as cracks. Allow resin to cure fully at room temperature away from drafts, fans, and cold window surfaces.

Resin Takes Long Time to Set – In cold conditions below 70°F, resin cures considerably slower. Use small space heaters or sunlight to gently warm the casting area for quicker results.

Embellishments Floating Up – Objects may gradually work their way upwards through the resin as it cures. Press them into a thin starting layer of resin and allow to partially harden before flooding the full mold.

Safety Best Practices When Working with Resin

Take proper precautions when using resin:

  • Work in well-ventilated areas to minimize inhaling fumes. Consider wearing an organic vapor respirator.
  • Avoid resin contacting skin. Wear disposable nitrile gloves and long sleeves when mixing and molding. Wash hands after.
  • Only use resin products as directed. Carefully measure equal parts resin and hardener.
  • Prevent resin from going down drains which can clog pipes. Properly contain and dispose of waste.
  • Supervise children around resin. Consider their shorter stature and greater susceptibility when assessing ventilation setups.
  • Never microwave resin. Only apply indirect heat like warm water baths or sunlight to help cure resin faster.


With quality silicone molds and clear casting resin, you can create dazzling jewelry pieces with depth and polish. The possibilities are endless between selecting from thousands of detailed mold varieties and deciding which special contents to embed within each piece before the resin cures permanently.

Jewelry molds allow efficiently reproducing multiple copies of designs with precision detail. But you also have the freedom to give each piece individuality by mixing in colors, glitter, found objects, and more. Simply add premade bails and findings to transform resin molding creations into professional quality pendants, charms, and focal beads.

Let resin molding open new doors for bringing your most elaborate jewelry visions to life!
