Silicone Mould

Rectangular Jewellery Silicone Mould

This silicone mould is designed for casting rectangular jewellery components, offering a clean, modern shape that works especially well for earrings, pendants and minimalist jewellery designs. The straight edges and balanced proportions make it ideal for bold colours, layered pours or simple transparent finishes.

Each cavity includes a pre-formed hanging hole, allowing finished pieces to be assembled without drilling. The flexible silicone material helps ensure smooth demoulding while maintaining crisp edges and flat surfaces.
