5" Diamond Cut Heart Mould

The 5" Diamond Cut Heart Mould is a faceted silicone mould designed for epoxy and UV resin casting. The geometric diamond-cut pattern creates a stunning multi-faceted surface on the finished piece, catching light beautifully — ideal for decorative hearts, paperweights, photo resin pieces, and personalised gifts.

Made from flexible silicone, this mould releases cured resin cleanly without tearing or distorting the sharp facet edges. At 5 inches, it gives you a bold, display-worthy size that works equally well with transparent resin, pigments, alcohol inks, dried flowers, or glitter inclusions.

• 5-inch size — large enough for statement décor pieces, gifts, and resin art displays
• Diamond faceted design creates a crystal-like, light-refracting finish on cured resin
• Flexible silicone construction allows easy demoulding without damaging fine facet edges
• Compatible with epoxy resin, UV resin, and polyester resin casting
• Smooth interior surface produces a glossy, pour-ready finish — minimal sanding needed
• Reusable and easy to clean — rinse with warm water or wipe with isopropyl alcohol after use
• Great for embedding dried flowers, photos, foils, glitter, or pigment pours

How to Use

Mix your epoxy or UV resin as per the manufacturer's ratio. Pour slowly into the mould to avoid air bubbles, or use a heat gun or torch briefly over the surface to pop any bubbles. Allow full cure time before demoulding — typically 24–48 hours for epoxy resin. For UV resin, cure under a UV lamp in layers for best results.

Safety Tips

Always wear nitrile gloves and work in a well-ventilated area when handling uncured resin. Keep resin materials away from children. Do not use this mould for food or candle applications.
