What Our Customers Say...

  • This helped my boyfriend so much! He didn’t know anything about buying jewelry, let alone an engagement ring. The buying guide was so helpful for him! We also figured out both of our ring sizes, and I tried on diamond cuts I’ve never tried before. After trying them on, I discovered I want a different shape that I never thought I would want! 10/10 recommend! I will be telling my friends about this!

  • This kit was absolutely perfect. I had picked out some rings on Pintrest but I didn't actually know if I liked them! So once I got this, turns out I loved something completely different then what I initially thought! Perfect for someone who wants to try on different rings types in the comfort of your own home!
