Helpful sizing tips
Fingers on a dominant hand are generally slightly larger than on non-dominant hands— make sure you measure the right finger on the correct hand!
Rings with wider bands will fit a bit tighter. Consider selecting one 1/4 to 1/2 size up from your normal ring size.If you plan to measure one of your partner's rings, try to measure one with a similar width as the ring you want to purchase.
For stacking rings: for a more comfortable fit, consider selecting one 1/4 to 1/2 size up from your normal ring size.
Make sure the finger is at normal body temperature — fingers can shrink or expand when hot or cold.
Your fingers tend to change size throughout the day — the best time to measure your finger is the end of the day.
If your knuckle is bigger, take 2 measurements and choose a size in between — ring needs to fit over knuckle but not be too loose or it will shift around.

Stunning engagement ring with a large fair trade, cushion cut green Montana sapphire in a unusual setting that shows off the beauty of this rare gemstone. Sparkling silvery greenish gold color Montana sapphire with outstanding brilliance and excellent clarity. The natural sapphire is an unheated Fair Trade level 1 stone.
Sapphire specs:
Weight: 1.49ct
Size: 6.5mm x 6.5 mm x 4.2 mm
Shape: square cushion cut
Clarity: VS ( Eye Clean - Very slight feather inclusion in one corner, inclusions can be seen under 10x magnification)
Treatment: None
Origin: Montana, Fair Trade level 1 stone
For this unusual gemstone I designed a half bezel ring setting that will show off it's spectacular beauty.The 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 6.5-7 mm. The ring was carved out of wax (see last image). It will be cast in your precious metal of choice and hand finished.
The sapphire is sourced from Columbia Gem House, a true pioneer in the fair trade gem marketplace. Fair Trade Gems are closely tracked from mine to market to ensure that every gem has been handled according to these strict protocols. Using ethically sourced gemstones with recycled metals makes this an Eco-conscious engagement ring.
Ring is Made to Order- for the most up-to-date fabrication time frame please check my listed turnaround times below in the footer area.
the yellow gold ring images are computer generated renderings to show the design from multiple angles. I designed and modeled the ring in a 3D software. The final ring will be made by carving a model from a wax block (see wax model in last picture), cast in a precious metal, hand setting the gem stone and finishing the ring. The ring will be customized for your specific ring size and additional options if requested. It will look very similar to the renderings shown.
Ordered a 5mm hammered band with scattered moissanite,, and it is just gorgeous. Kostanze was so wonderful to work with. I wouldn't hesitate to custom order through nodeform again. The only hitch is that I live in Canada and had to pay additional duties and taxes when the ring arrived. Other than that... Love it!
I bought the Velda ring in rose gold with alexandrite stones and couldn’t be happier! Konstanze helped me determine how it might look as a shadow band with my engagement ring (pictured). It looks better than I even imagined and I am so thrilled! Konstanze was great at keeping in touch, answering questions, and it didn’t hurt that it came so nicely gift wrapped. My husband and I did all our wedding jewelry in-person at our local store (pre-pandemic) and I didn’t know what to expect with an online experience, but it was very personal and turned out perfectly. Thank you!
