Keepsake quality vs Quick quality

I was recently talking with other keepsake artists, and honestly, I was taken back by how quickly people jump on the “UV resin is fine” train.

Yes, UV resin has improved. No one is denying that. But so has two-part epoxy. Just because something is better than it was 10 years ago doesn’t automatically make it the right choice, especially when we’re talking about keepsakes that are meant to last.

If you’re calling your work heirloom quality, the material choice should reflect that.

To me, the only real advantage of UV resin is for very specific placement, like setting hair or holding delicate elements exactly where you want them. Even then, that’s a tool, not a foundation. Most of those same results can be achieved with epoxy using layers, suspension techniques, or even something as simple as fishing line.

What concerns me is how often UV gets justified:
“It’s come a long way.”
“If the setting is sturdy, it won’t matter.”
“Two-part is wasteful.”

Those aren’t material arguments, they’re workflow arguments.

The reality is, the chemistry hasn’t changed in a way that suddenly makes UV comparable to epoxy in durability. Epoxy forms a stronger, more stable bond because of how it cures. That translates to better resistance to scratching, heat, and long-term stress. UV resin cures fast, but that speed comes at a cost, lower structural integrity and increased brittleness over time.

That’s not opinion, that’s material science.

And the yellowing argument? That one always raises a red flag for me. All resin yellows eventually. That’s just reality. But UV resin tends to yellow faster due to the photoinitiators required for curing. High-quality epoxies, especially those used in jewelry, often include stabilizers that significantly slow that process.

So when someone says “UV doesn’t yellow,” it usually tells me more about their marketing than their materials.

At the end of the day, this often comes down to convenience. UV resin is faster, easier for small batches, and more forgiving in a production workflow. That doesn’t make it better, it makes it more convenient.

And convenience shouldn’t be the deciding factor when you’re creating something meant to last.

For me, UV has a place, but it’s not the backbone of a keepsake piece. Relying on it as a primary material while marketing work as heirloom quality doesn’t sit right.

Two-part epoxy is still the more durable, stable option for keepsake work.

Bottom line: recommending UV resin as a primary material for heirloom pieces feels careless. Not because it’s unusable, but because there’s a clearly stronger, more reliable option available.
