Charming and elegant

I love the elegant simplicity of this necklace and have been wearing it most days since it arrived! It is perfect and I love it.

Beautiful, quality work!

Great communication throughout the ordering process and while waiting for the custom order to be completed. The ring turned out beautiful and is very well made. My significant other loves it and has been receiving a lot of great compliments. Very happy with the purchase! (Purchased along with the Moissanite Round Full Bezel Set Star Dust Engagement Ring.)

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.

BEAUTIFUL!! Perfect wedding band!

This was such a great purchase! It was the perfect band to go with my gold engagement ring. Seller was so communicative and great to work with
