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.

Love it!

This is my 2nd piece from Konstanze and I love it! I hope to be able to buy more from her in the future! I love wearing silver, and it's hard to find someone put this level of live and design into pieces made from recycled silver. I'm super pleased with my new moissanite ring, it matches my style perfectly!

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!!

Better in real life

It was such a joy to be able to choose my own Stone for my 50th gift. The Montana sapphire was the perfect size and colour. I will definitely use Nodeform again.

Perfect

This setting was exactly what I was looking for and it was even better when it arrived.

Stunning

I love my engagement ring. It is stunning and truly a piece of art.
