Why Does My Resin Jewellery Turn Yellow? Prevention & Tips

← Back to how to make jewellery with resin tutorial

Yellowing is a common issue for resin jewellery, especially for those wanting to preserve their creations’ clarity and vibrance. Understanding why it happens is the first step to keeping your pieces looking striking over time.

What Causes Resin Yellowing?

The main reason resin jewellery turns yellow is exposure to ultraviolet (UV) light. Sunlight, as well as artificial lighting, can cause gradual colour changes in resins that lack proper protection. Inferior or outdated resins also tend to lose their clarity more quickly. Over time, even a well-made piece may develop a yellow tint if it’s left in direct light or exposed to heat.

How to Prevent Yellowing of Resin Jewellery

To help keep your jewellery bright and clear, choose resins that include UV inhibitors or filters. These additives provide extra resistance to UV-related discolouration. For example, the One-2-One Epoxy Resin contains a UV filter designed to reduce yellowing. Additionally, store your finished pieces away from prolonged sunlight and avoid leaving them near radiators or heat sources.

Use up-to-date, high-quality resin for each project.
Work in a well-ventilated area to minimise yellowing from heat during curing.
Keep finished jewellery in a cool, dark place when not in use.

When This Matters Most

If you’re making transparent or pale-coloured jewellery—such as encapsulating flowers or adding subtle pigments—yellowing will be more noticeable. It’s crucial to use resins with UV stabilisers and take care with storage for these projects.
