1 item left

Stunning engagement ring with a fair trade, cushion cut teal blue-green to seafoam green color Malawi sapphire in a modified tension setting.

The fancy colored fair trade genuine sapphire will be hand set and the ring has a mirror polished finish. The band width is about 3 mm. Height above the finger about 6 mm for the 5mm stones and up to 7.5mm for the deeper cut 6.5mm sapphires. The first pictured sold rings were all made with 5mm sapphires in various green to teal-blue colors, last images show a finished platinum ring with a 6.5mm sapphire (F8 (SOLD).

The faceted sapphire may have a few tiny needle or feather inclusions that can be seen at magnification, but they eye-clean at arms length. Please see last pictures for sapphires I have available. Select your sapphire from the drop down menu and indicate your preference if there are more than one available within the selected color/size (availability may change). Price varies depending on color and size of the sapphire.

Konstanze was so wonderful to work with, and was professional, communicative, and responsive throughout the entire process. She produced two beautiful rings with unique and amazingly colored fair-trade sapphires - all within my budget. She went above and beyond expectations to find the stones I was hoping for, and the rings are even more beautiful than I expected them to be. I'm SO excited about them, and I KNOW my partner will love hers. THANK YOU!!!

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.
