Single cubic zirconia plug earring as gift

I'm interested in buying some earrings. I like the Gold Square CZ Stud Earrings that I saw on your website. However, they are a little too expensive for me. Do you have any other earrings that are similar? I'm open to other metals, such as silver, but I really like the square shape. I'm also interested in seeing if you have any other styles in a similar price range. I'm looking forward to hearing from you.
