Looping Through Metafields In Shopify

I need to display n number of images for a product in shopify.

I have stored number of images in a metafields and created a loop for it.

Then each image's name is stored in a metafield, which i am trying to get with help of loop.

{% assign earrings = product.metafields.earrings %}

{% for i in (1..earrings.total-earrings) %}
  {% assign earring = 'product.metafields.earring-' | append:i %}
  {{ earring.name }}
{% endfor %}

This loop is giving me values for earring like:
product.metafields.earring-1
product.metafields.earring-2

but when i am trying to read value of metafield earring.name, i am not getting any output. I think because product.metafields.earring-1 is a string.

Is there any possible way to loop through metafields like this and get values?

Just in case it's helpful for someone.

Here's the updated code:

{% assign earrings = product.metafields.earrings %}

{% for i in (1..earrings.total-earrings) %}
  {% assign dummy = 'earring-' | append:i %}
  {% assign earring = product.metafields[dummy] %}
  {{ earring.name }}
{% endfor %}
