Helpful sizing tips

  1. Fingers on a dominant hand are generally slightly larger than on non-dominant hands— make sure you measure the right finger on the correct hand!
  2. Rings with wider bands will fit a bit tighter. Consider selecting one 1/4 to 1/2 size up from your normal ring size.If you plan to measure one of your partner's rings, try to measure one with a similar width as the ring you want to purchase.
  3. For  stacking rings: for a more comfortable fit, consider selecting one 1/4 to 1/2 size up from your normal ring size.
  4. Make sure the finger is at normal body temperature — fingers can shrink or expand when hot or cold.
  5. Your fingers tend to change size throughout the day — the best time to measure your finger is the end of the day.
  6. If your knuckle is bigger, take 2 measurements and choose a size in between — ring needs to fit over knuckle but not be too loose or it will shift around.

Son's girlfriend trusted my judgment on her engagement ring

This was the most special thing I have done in a very long time. The process was so easy and covered every base. The ring turned out absolutely perfect. My son and his girlfriend got engaged last weekend and sh could not have been more thrilled.

So Beautiful & Unique

I absolutely love my custom ring from Nodeform. Konstanze was communicative and helpful throughout the process, and created a stunning piece of art. I was thrilled with how quickly my order was produced and shipped! The bezel setting was very important for me as someone who works hands-on with people, and I feel comfortable wearing my engagement ring everyday without fear of damaging it or prongs snagging/loosening.

Exactly what I was hoping for!

The rings Konstanze made for me are beautiful and go together wonderfully even though they were made separately. I was nervous about purchasing jewelry online, but Konstanze made the process easy, made excellent suggestions, and kept me informed throughout. Thank you so much, the rings are perfect!

SPARKLY AND SO BEAUTIFUL

When I opened the box, the ring was more beautiful than I imagined. It highlights my sapphire engagement ring and provides a band of beautiful, bright sparkle. I absolutely love this ring!!! My husband, who is not a fan of jewelry, really likes the unique design of the two rings.

Konstanze was wonderful to work with – patiently answering my questions and doing everything she could to ensure we got the rings I wanted! I am a repeat customer and will be back again. Thank you Konstanze!!
