I am happy this special color-change Sapphire ring found a new loving home. If you want to have something similar made just for you please contact me. I can source similar sapphires for custom designs. 

Mixed Metal engagement ring with a round color-change Songea Sapphire, set in an elevated rose gold bezel on a narrow palladium ring shank.

Sapphire Spec:

Weight:   ~1.86 ct
Size:    7mm diameter
Shape:    round cut
Clarity:     Eye clean (very fine silk only visible at high magnification)

Treatment:    None
Origin:    Songea, Tanzania

The sapphire changes colors from a blueish-green to a reddish purple in certain lights and viewing angles. Natural untreated Sapphire from the Songea mines in Tanzania has some of the most unique colors and combinations of color that I’ve ever seen in any gem material.

The sapphire was cut by award winning gem cutter Larry Woods in a his trademark medicine wheel round shape design.

The uniquely cut genuine sapphire was hand set. The palladium ring shank can have a satin brushed finish (as pictured) or mirror polished finish if requested. The band tapers in width between about 2mm at the bottom to 3mm towards the setting. Height above the finger about 6.9mm.

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.
