John Dyer Montana Sapphire Diamond Star Dust Halo Bezel Palladium Engagement Ring, Size 4-9

1 item left

Ethical palladium engagement ring with a uniquely cut light blue-green Montana sapphire in a low profile diamond-encrusted Star Dust halo.

The sapphire was cut by award-winning gem cutter John Dyer in his signature Ripple™ design. The genuine un-treated sapphire has a gorgeous play of light. It is a very lively stone with excellent cutting. It looks like a larger gem because the cut is very shallow yet still brilliant due to the special cutting technique.

Sapphire specifications:

  • Weight:     1.06ct
  • Size:         6.3 x 6.3mm x 2mm
  • Shape:     round Ripple Top™ cut
  • Color:       light blue-green
  • Clarity:     Eye Clean - very small inclusions under magnification
  • Treatment: None
  • Origin:     Montana, USA

The RippleTop cut has waves carved into the top which give a liquidy brilliance reminiscent of the Missouri River near where this gem was found in the mining region of Montana, USA.

The Halo around the center stone has 12 flush set ethical diamonds, 4 recycled Harmony diamonds size 1.25mm /0.008ct (color G-I, Clarity SI), and 8 smaller Canadian diamonds in size 0.95mm/0.004ct diamonds (color F-G, Clarity VS ), 0.064TCW. The halo is textured with tiny engraved circles to create a Star Dust appearance.

The palladium ring has a fine satin-brushed finish. The band is about 2.5-2.9mm wide. Height above the finger about 3.6mm. The 2mm wide halo creates a beautiful picture frame for the sapphire.

Ring is ready to ship in size 5.5 and can be resized between size 4 to 9. ** Please specify ring size.**

perfect fit, perfect ring, Fiancé loved it and said yes :)

Love this ring!

I got 6mm stone in platinum and absolutely loving it every day for almost a year!!!! Great quality, very thoughtful details, and looks like brand new every time you clean it with dish soap! Will definitely order matching wedding band as soon as needed ;)

Iryna, Thank you so much for your lovely review. So glad you love your ring. I will be delighted to make your wedding band, too.

Incredible Engagement Ring

Everything was perfect! I was nervous ordering such an important piece of jewelry, but the attention to detail was top notch! I was probably a little too much with all of my questions, but everyone was patient, answering all of my questions about the ring, delivery, etc. I highly recommend Nodeform!

Thank you so much for working with me to create this special ring for you both!

Love my Rings!!

Nodeform had amazing communication from the beginning, and worked hard to make sure I got exactly what I wanted. My rings are both absolutely stunning!

Just what I wanted...

I've wanted to upgrade the sparkle, size of stone and style of my vintage mis-matched wedding set since my 5th anniversary or so...two kids and 16 years later Nodeform has helped me do just that! Spotted her work on Etsy three or more years ago and kept coming back to it. It took me a little while to come around to Moissanite, but once I realized I could have the modern look and amount of bling that I wanted for a fraction of the price, that was it. I'm not a mommy who wants to wear thousands on her finger; now I just look like I do;-). The rings are beautifully crafted and just what I wanted! I'm so glad I finally pulled the trigger.

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!

Beautiful Craftsmanship

I cannot express how excited I am about my beautiful ring. It is exactly as anticipated. I ordered a small (4.25) thin (3mm) hammered edge band, with a comfort edge.

The customer service was excellent! Shipping was fast. I love buying from small businesses, but the level of detail and amazing customer contact was phenomenal!

Wonderful creative design

I LOVE my ring!!! It is so beautiful- bright silver with the awesome pattern would like to get two more narrow ones to wear with it!!

Perfect tiny stud earrings

Exactly what I wanted: grey (my favorite color) diamonds set in platinum (hypoallergenic), lightweight for every day. Thank you!
