When making costume jewellery with resin, you might come across the term ‘UV filter’. Understanding what a UV filter does helps you choose the right resin and keep your pieces looking their best.
What Does a UV Filter Do?
A UV filter in resin acts to minimise the effects of ultraviolet light exposure on your finished jewellery. Without this protection, clear resins can gradually develop a yellowish tint, especially when exposed to sunlight. UV filters are incorporated to help preserve the clarity and gloss of resin pieces for a longer time, making your jewellery more resistant to discolouration.


Choosing Resin Drops for Jewellery with UV Protection
If you’re planning to craft costume jewellery that stays bright and clear, check whether the resin mentions a built-in UV filter. For example, “ICreation” Fast Epoxy Resin offers UV protection to help defend against yellowing. Many fast-curing UV resins also benefit from this feature for a lasting sheen.
When UV Filtering Really Matters
- You sell or gift jewellery that could be worn frequently outdoors.
- Your designs use clear or light-coloured resin drops prone to visible yellowing.
- You want pieces to retain their brightness over time.
