A cheap resin mold leaves cloudy seam lines on every piece you pour. You end up sanding for longer than you spent casting, which kills the fun fast.
Good silicone molds pop pieces out glossy on the first try. The best ones also have built-in hanging holes so you don’t need to drill into cured resin later.
This list covers 10 mold kits for earrings, pendants, cabochons, and rings. Kits range from a simple 4-piece starter set to the LET’S RESIN 171-piece box with 80 pairs worth of hooks and jump rings included.
We compared them on cavity count, hole placement, release quality, and how well the silicone flexes at demolding time. The quick comparison chart below lays out the key differences.

How We Scored the Field
Cavity count, built-in hole placement, release quality, and how cleanly the silicone flexes at demolding time drove the rankings below. The top three picks each serve a different casting style: mixed pendant shapes, earring-focused production, and domed cabochon work.
Further down, you’ll find bulk kits for market booth inventory and niche molds for cat lovers and ring makers. Scores reflect how well each mold handles repeated pours without losing detail or developing sticky spots.
1. Resin Jewelry Molds Reusable Casting Tray — Best Overall
Reusable casting tray with pre-drilled holes for epoxy pendants, earrings, and bookmark blanks.
Pros
- Assorted shape resin jewelry mold tray
- Built-in hanging holes skip the drilling step
- Works with epoxy, cement, wax, and polymer clay
- Measures 9.2 by 8.5 inches for batch casting
- Mixed shapes mean fewer of each design
- Built-in hole posts can leave a small bump
- Single tray bottlenecks larger DIY production runs
MAQIHAN’s reusable casting tray packs multiple pendant, earring, keychain, and bookmark shapes onto a single 9.2 by 8.5 inch silicone sheet. Hanging holes are molded into each pendant cavity, so finished pieces come out ready for jump rings without separate drilling work.
The tray handles epoxy resin, cement clay, wax, and polymer clay equally well, making it the jack-of-all-trades pick for jewelers testing new materials. Mixed shapes on one tray do mean fewer of any single design per pour, so serial crafters may want multiple trays.
For production-scale earring work specifically, the rank-2 Roxjaejae 46-piece kit with matched hooks and jump rings handles that use case better. Finished silicone earrings cast from molds like these sell well at craft fairs alongside resin pendants.
2. Roxjaejae 46 PCS Resin Earring Molds Kit — Runner Up
46-piece earring mold kit with built-in jump-ring holes for fast pendant production.
Pros
- 46-piece kit with 6 molds and metal findings
- 10 gold and 10 silver earring hooks included
- 10 gold and 10 silver jump rings for assembly
- Classic geometric shapes in multiple sizes
- 46 pieces overwhelm beginners with too many shapes
- Built-in holes can clog with resin if overfilled
- Smaller mold pieces flex during careful pours
Roxjaejae’s 46-piece kit bundles six silicone molds with 40 metal findings split across gold and silver finishes. Built-in holes eliminate drilling, and the hook plus jump ring allotment supports roughly 20 full pairs with findings to spare.
Geometric shapes like circles, ovals, triangles, teardrops, and diamonds keep the designs timeless enough for any outfit. Beginners can get overwhelmed by 46 pieces on the first pour, so batch production across multiple sessions handles the full kit without rush.
Against the rank-1 MAQIHAN reusable casting tray, Roxjaejae trades mixed-shape versatility for bundled metal hooks and jump rings ready for earring assembly.
3. LET’S RESIN Cabochon Gems Resin Molds — Best Value
36-cavity cabochon kit with 16 metal pendant trays for cast-and-set jewelry projects.
Pros
- 36 cabochon gem cavities across 2 molds
- 16 metal pendant trays included
- Thick 0.4 inch domed 3D finish
- Compatible with epoxy and UV resin
- Cabochons need separate setting work after casting
- 16 pendant trays run out before the molds wear
- UV resin focus needs a curing lamp purchase
LET’S RESIN’s cabochon kit targets crafters making domed gemstone-style jewelry with a 0.4 inch cavity depth that exceeds standard flat-pour molds. The 16 included metal pendant trays let finished cabochons drop directly into a setting without extra sanding.
Thirty-six cavities across two molds cover small and medium cabochon sizes, though the pendant trays only fit the smaller cavities. Pair this kit with a UV curing lamp for fast turnaround times.
Epoxy works too but adds overnight cure times. Against the rank-1 MAQIHAN reusable casting tray or the rank-2 Roxjaejae earring kit, LET’S RESIN focuses on domed cabochon-style pieces rather than flat pendants or earrings.
4. 104Pcs Geometric Resin Earring Molds Kit
104-piece geometric kit with 100 hooks for crafting dangle earring sets in bulk.
Pros
- 4 geometric molds plus 100 metal findings
- 50 gold jump rings and 50 gold earring hooks
- Built-in holes skip the drilling step
- Makes up to 50 pairs of earrings
- Hooks are basic plated steel, not stainless
- 104 pieces overwhelm a single casting session
- Geometric shapes limit traditional jewelry styles
XBYzuzi’s 104-piece kit covers four geometric molds with 10 to 15 cavities each, plus 50 pairs worth of gold earring hooks and jump rings. One buy covers a small-business starter volume or an extended family gift run.
Teardrop, circle, hexagon, flower, leaf, oval, triangle, and dangle shapes spread across the molds for mix-and-match dangle earring sets. Plated hooks are basic compared to stainless steel, so upgrade findings on sensitive-ear buyers.
5. LET’S RESIN 171 Pcs Resin Jewelry Molds
Massive 171-piece variety kit for crafters making mixed earring and pendant collections.
Pros
- 11 mold shapes across 171 total pieces
- 80 gold and silver jump rings for assembly
- 80 earring hooks in gold and silver
- Supports up to 80 pairs of finished earrings
- 171 pieces clutter small craft workspaces
- Eleven mold packs need careful labeling
- Variety dilutes focus on any single style
LET’S RESIN’s 171-piece kit is the bulk option for buyers ramping up a small jewelry business or running a big gift season. Eleven mold shapes each carry 6 to 8 cavities, and 160 metal findings supply 80 earring pairs with jump rings.
Variety comes with a tradeoff. Eleven molds need careful labeling and storage, since mixing them up across pour sessions slows production.
Heat guns and torches aren’t recommended, so depressurize bubbles with a poke-and-tap method instead.
6. Waterdrop & Oval Resin Jewelry Molds
Six-cavity waterdrop and oval pendant mold for classic gemstone-style resin necklaces.
Pros
- Six cavities split between waterdrop and oval shapes
- Built-in hanging holes for pendant work
- Non-stick surface for easy demolding
- Works with epoxy, silicone, and UV resin
- Only six cavities slow batch production
- Limited to two shapes, no shape variety
- Hanging holes too narrow for thicker chains
Azefnuhk’s six-cavity pendant mold focuses on the classic waterdrop and oval shapes that drive gemstone-style necklace designs. The 7.09 by 3.94 inch footprint stores flat in a drawer between sessions.
Two shapes only limits variety for crafters wanting bigger design libraries, but this mold nails the traditional pendant look better than assorted-shape trays. The finished pendants hang nicely on a silicone necklace cord for a fully handmade piece.
Dried flowers, gold foil, and mica powder inclusions photograph cleanly against the waterdrop silhouette.
7. Actvty Earring Resin Mold with Holes
Compact four-piece pendant mold set for crafters trying epoxy jewelry for the first time.
Pros
- 4-piece starter mold set for pendant and earring work
- Pre-drilled holes for jump ring attachment
- Multiple shapes including moon, star, heart, and waterdrop
- Compatible with epoxy, UV resin, and polymer clay
- Only four pieces, limited shape variety
- Beginner-focused set lacks pro-level detail
- Small molds slow batch jewelry production
Actvty’s four-piece set is the starter kit for first-time resin jewelers testing whether the hobby sticks before buying a full 100-piece kit. Each mold carries multiple shapes like moon, star, heart, oval, waterdrop, and rectangle.
Pre-drilled hanging holes mean finished pieces don’t need separate drilling, a major barrier-lowerer for beginners. Small four-piece footprint slows batch production but keeps upfront cost low for trial runs.
8. Resin Earring Mold with Holes (White)
Four-piece white mold set with irregular shapes for boho-style resin earrings.
Pros
- 4 irregular-shape pendant molds
- Pre-drilled holes eliminate drilling step
- Glossy smooth interior for crystal-clear finish
- Works with UV resin, gypsum, clay, and cement
- White silicone stains from colored resin pigments
- Irregular shapes harder to pair into matching sets
- Four molds limit experimentation with colors at once
Wugyux’s white four-piece set leans into irregular pendant shapes for bohemian or asymmetric earring designs. Pre-drilled holes and a glossy interior finish eliminate the main post-pour tasks that slow beginners down.
Multiple cavities per mold spread across moon, star, heart, oval, waterdrop, rectangle, and octagon shapes. White silicone can stain from colored resin pigments, so buyers doing dark-color work should consider the clear variant instead.
9. 4 Piece Resin Earring Molds (60 Cat Shapes)
Four-piece set with 60 cat-themed and animal cavities for novelty pet-lover gifts.
Pros
- 4-piece set with 60 unique cat and animal shapes
- Pre-made holes for findings attachment
- Flexible silicone for easy demolding
- Great for UV resin pet-themed jewelry
- Cat theme limits broader gift appeal
- 60 small cavities per tray fill slowly
- UV resin requires a separate curing lamp
FWKAILEPING’s cat-themed four-mold kit spreads 60 animal-inspired cavities across four silicone trays, targeting the novelty pet-lover gift market rather than general jewelry making. The variety reads as a focused collection rather than random shapes.
Pre-made holes across every cavity mean findings drop in without drilling. UV resin is the recommended fill for fast cures and crystal-clear cat-shape finishes, though epoxy also works for overnight pours.
10. Resin Ring Molds, Set of 3 (24 Sizes)
Three-piece ring mold set spanning 24 sizes for casting custom resin rings.
- 24 ring sizes cover US 4 through 12+ in one kit
- Cast rings cost cents each in resin once the mold's yours
- Flexible silicone demolds cured rings without shearing
- Great for matching sets and gift-ring projects
- Lets you experiment with inclusions and pigment
- Rings need post-cure sanding for smooth wear
- 24 sizes split across only three molds
- Thin ring walls crack under demolding pressure
LCcakem closes the list with a three-piece set of silicone ring molds covering 24 different ring sizes between them. The volume here is the value.
Instead of buying separate single-size molds, you get the full size range in one purchase, which is what someone making custom-fit resin rings actually needs.
Each mold is food-grade silicone with a smooth interior surface that releases cured resin without sticking, sanding, or tedious trimming. The molds work for jewelry projects beyond rings: earrings, small pendants, necklace charms, and keychain inserts all fit the cavity sizes.
Storage matters here because the silicone holds shape better when kept at room temperature away from direct sunlight.
Three molds covering 24 sizes means each mold splits cavities across multiple ring sizes, so you can’t pour all sizes simultaneously without a long setup. Thin ring walls also crack under aggressive demolding pressure, so flex the mold gently when releasing finished pieces.
Rings benefit from a quick post-cure sanding pass for a smoother feel against the finger.
Frequently Asked Questions
Is silicone jewelry safe for sensitive skin?
Medical-grade silicone is generally considered hypoallergenic, the same material used in silicone necklaces and teething jewelry. It and doesn’t contain nickel, lead, or the other metals that trigger most contact allergies.
It’s a common swap for people who can’t wear stainless steel earrings or who react to costume jewelry.
Does silicone jewelry tarnish or rust?
No. Silicone is corrosion-resistant, waterproof, and won’t oxidize, unlike sterling silver, brass, or plated costume pieces.
You can wear it in the shower, the pool, or the gym without worrying about tarnish, which makes silicone rings and bands ideal for people who work with their hands or exercise daily.
How do you clean silicone jewelry?
Warm water and a drop of dish soap is usually enough for routine cleaning. For deeper cleaning, soak the pieces in soapy water for 10 minutes, then gently scrub with a soft toothbrush in the crevices to remove any buildup from lotions, sunscreen, or sweat.
Can silicone jewelry be worn in water?
Yes, showering, swimming, hot tubs, and ocean water are all fine. Silicone doesn’t absorb water and won’t degrade from chlorine or salt, which is why it’s the go-to ring material for swimmers, nurses, mechanics, and anyone whose job or lifestyle involves constant water or chemical exposure.
Will silicone jewelry stretch out?
Silicone stackable rings and bands are designed to flex; they’ll return to shape after normal wear. Cheap jewelry-grade silicone can stretch permanently over years of use, but medical-grade pieces generally hold their shape for the life of the item.
Can you make silicone jewelry at home?
With the right resin mold kit, yes, most of the molds on this list are designed for pouring UV or epoxy resin into silicone cavities to create pendants, earrings, and ring blanks. Silicone rubber casting (for flexible silicone pieces, not hard resin) requires a two-part platinum-cure silicone and is more of a specialty craft.
Final Thoughts
The Resin Jewelry Molds Reusable Casting Tray takes the top slot because the variety of pendant and earring shapes covers most jewelry projects in a single purchase. Reusable design also means the same mold delivers dozens of finished pieces over its lifetime.
The Roxjaejae 46-piece Resin Earring Molds Kit runner up bundles earring-specific shapes and findings, which lets beginners assemble finished pairs without sourcing components separately. Useful for first-time resin jewelry makers.
The LET’S RESIN Cabochon Gems Resin Molds value pick focuses on round and oval cabochon shapes, which suit pendant and ring projects. Lower price than the multi-shape sets when you only need one shape style.
For active wearers, a stack of silicone bands pairs naturally with silicone sports watches for a full workout-ready look. The same break-away safety logic applies to both bands and watches when working out around weights and equipment.
