Adding Icons under product image on collection page

[LumelleWear]

Hello, I'm wondering how to add icons under the image of each product. The drops are supposed to symbolise how much each product handles. So much like a "rating" it would just be drops filled or unfilled, they differ from product to product so changing the overall product template wont work. Look at examples pictured: 

I am using the dawn theme and here is the url to my website: LumelleWear.com 

Thanks for any help in advanced!!
