"Oh...it's the sky that night you woke me to see the Milky Way", she said

This ring is a lovely piece of wearable art that was particularly meaningful to us, but its simple elegance will move anyone you might give it to. Konstanze was responsive to my changed order (how do you mis-measure a finger you've known for 33 years? I can't answer that) and my stupid questions about which ring might work best (the wearer does surgery, so a traditional engagement stone was not practical for her). I'm not saying that a clandestine measurement of a ring she already wears and a private unexpected proposal is for everyone but this ring definitely worked for me.

Such a beautiful ring!

This is a repurchase, I lost my wedding band on a road trip and desperately wanted it back. Konstanze made my ring again and sent it out quickly and I am so happy. The ring is not too thick, not too thin, very comfortable and clearly well made. I love the comfort fit! My initial ring was on my finger for a year and a half. I'm a nursing student and wash my hands constantly, but the stones always stayed perfectly attached. The ring is shiny with perfect little blue and white stones. Super classy!

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

My fiancee loves it

Looks better in person. Quality is amazing.


My trillion Moissanite stud earrings exude an understated elegance. The bezel setting frames the dazzling stone, which is the perfect size for everyday wear.

above and beyond

I cannot say enough about how much I appreciate Konstanze's craftsmanship and customer service. My husband bought my engagement ring nearly three years ago from Nodeform and had to ask for some special requests during the buying process. Konstanze was extremely helpful and patient. The hoops my husband had to jump through to get this ring is one of the reasons why it is incredibly precious to me. So when the green moissanite chipped, I was heartbroken. I found a similar one on Konstanze's website recently, and she guided me through which one to buy that would fit the existing setting and answered all of my questions almost immediately. It was her awesome attention to detail and customer service that brought us back to her. I really cannot thank Konstanze enough and can't wait to have my gem replaced and ring back on my finger again. Thank you! (Attached picture is of the original engagement ring and green moissanite. :-) )

Amazing customer service and beautiful ring

Konstanze did an amazing job on this ring. She has amazing attention to detail and customer service to create a stunning custom ring. It looks even better in person than the photos. The subtle grey moissanite changes colour in different lighting from a very subtle to more obvious grey hue. Thank you for a ring I will cherish forever.
