Hello.
The product images appear blurry on mobile, when looking at the top-level of the store.
When you click the individual item, they are then clear. I have uploaded the images as 1920x1080px
You can see what I mean here:
The first pair shows a necklace as blurry before the click, and then sharp after.
The second pair shows a pair of earrings as blurry, and then sharp when you click the product.
Thanks for the help
