    1 item left

    One-of-a-kind engagement ring with a genuine untreated yellow-green Montana sapphire set in a semi-bezel setting. The unique sapphire was cut by Jeffrey Hapeman from rough from the Rock Creek deposits in the mountains of Philipsburg, Montana.

    Your ring will be custom-made with the sapphire shown laid into the sample mounting. Your ring will be made in your metal of choice to fit this very special and unique gemstone. The ring will be carved out of wax, cast in precious metal, handset, and hand-finished.

    The genuine untreated Montana sapphire has a gorgeous yellow-green color. It is a very lively stone with excellent cutting. The faceted Sapphire is about ~0.72 carat and measures 5.4 x 4.6 x 3.4 mm. It was faceted in a custom oval/cushion brilliant design to best utilize the natural shape of the gem rough.

    The color is an interesting mix as the gem had a golden yellow center and a blue-green rim.  In most lighting, it shows as a medium yellow-green.  Under fluorescent lighting, the color shifts to a more greenish yellow. In daylight, it can appear yellow to greenish-yellow depending on the angle its viewed.  Very unique!  The gem is completely natural and unheated and has outstanding brilliance with just a bit of glow from the silk. The silk you can see here in the photos is not visible in the hand and is proof that the gem has not been heated.

    Beautiful ring and wonderful service!

    My fiancé and I both love this ring! We were worried about buying online without seeing the ring in person but everything turned out amazing. The ring is beautifully crafted and Konstanze provided great customer service throughout the whole process.

    Great Ring

    Super comfortable ring to wear it almost feels soft for lack of a better way to put it. Really do enjoy wearing it

    Thank you so much! I love making this design and I am so happy you love your special ring!
    Happy New Year!

    She loved it!

    The ring came in as beautiful as I expected. Sizing was spot on.

    Yay! So happy to hear. Thank you so much for choosing me to make this ring.

    Beautiful ring!

    We saw Konstanze's fold design and really loved it. After looking around elsewhere, we didn't find anything as comfortable, elegant, and modern--it's truly unique.
    We purchased the 3# sapphire, and really love how its color shifts from a subtle green to a steely blue depending on the light.
    The ring arrived on time and with simple, at-home cleaning instructions. We highly recommend Konstanze and would (will!) buy from her again.

    At first I was wary

    At first I was wary about ordering a ring online without ever seeing it in person, but went for it anyways and couldn’t be happier!
    Great ring. Nicely polished. Delivery right on time with estimate. Professionally done!
    We’ll be ordering wedding rings to go with the engagement soon...
