Resin jewellery is made by pouring liquid resin into a mould, letting it cure into a hard, clear or coloured shape, and then fixing that shape to metal findings such as hooks, bails or ring bases. It is popular for light statement earrings, pendants and rings in bright colours or with objects set inside, such as dried flowers, leaves or flakes of foil.
Resin is a different craft from the cast and plated metal work that most Rajkot workshops are known for. Some makers offer resin pieces, but buyers should check whether the work is done in-house or bought in from a small specialist unit.
How resin pieces are made
- Moulds: most resin pieces are cast in silicone moulds, which are cheap to make, so new shapes can be sampled quickly.
- Resin type: two-part epoxy resin cures slowly at room temperature; UV resin cures in minutes under a lamp and suits thin layers and small pieces.
- Inclusions: pigments, mica powder, glitter, dried flowers or shell are mixed in or layered between pours.
- Finishing: edges are sanded and polished or given a final thin coat for gloss, then the piece is drilled or glued to its metal findings.
- Metal parts: hooks, frames and bezels are usually brass or alloy, plated gold or silver tone like any other imitation piece.
Strengths and weak points
Resin is light, so large earrings stay comfortable, and it takes almost any colour. It does not tarnish, which makes it a good partner for plated metal parts that do.
Its weak points are surface and colour. Resin scratches more easily than metal or glass, and many resins slowly turn yellow with long exposure to sunlight. Poor mixing or curing leaves bubbles, sticky surfaces or soft spots, and glued joints between resin and metal are the most common place for a piece to fail.
What to check on samples
- Clarity: no trapped bubbles or cloudy patches unless they are part of the design.
- Cure: the surface is hard and not tacky, and a fingernail does not leave a mark.
- Joins: findings are fixed mechanically where possible, not only glued to a smooth face.
- Consistency: colours and inclusions repeat closely enough across a batch for your listings and photos.
- Metal parts: the hooks and frames meet the same nickel, lead and cadmium limits as the rest of your range.
What this means for a buyer
Resin suits light, colourful fashion lines and gift ranges, but treat it as its own product with its own checks rather than an add-on to a metal order. Creston & Co works for buyers only, for a fixed fee agreed in writing, and checks finish, joins and test reports before a carton is sealed.
