Delicate and beautiful

Love my Natalie setting. I had it made with a round center sapphire, and the side stones add to the sparkle. A beautiful variation on a traditional solitaire.

Service and workmanship Exceeds!!!

Thank you, Konstanze! Once again, do you have exceeded our expectations! Our rings were returned as if they were new.
We already have the earring to match, now all we need is a matching necklace.
To be continued…. 😁

Made specially for me!

I first ordered the solitaire alexandrite ring, and a few days later I contacted Konstanze to add small alexandrites all around the band. She was kind enough to modify my order. There were a lot of questions from my side along the process and she even sent me pictures of the CAD model to have an idea of how the ring would look like. This is my third order from this shop and the product quality and customer service have always been great

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!


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!!
