Sparkly and fresh looking is a bright blue diamond in a Guinevere four-band puzzle ring with an open weave and a narrow 1.65 mm wide shadow band. A Celtic knotwork inspired puzzle weave suggests the never-ending love in your marriage. 

A working puzzle ring, styled after legendary Celtic knotwork rings, this ring comes apart and goes back together easily with the video, animated, and written instructions we provide under a link below on this page. Rarely will you find a diamond engagement ring that will provide such fun and fascination.

Your puzzle ring will be hand-woven, in contrast to the majority of puzzle rings which are cast from molds. Our brilliant puzzle ring artist will custom weave your engagement ring precisely for the very stone you select, its very shape and size, so your puzzle ring will be a true, one-off original.

Your options: The base price on this page is for this ring in palladium with a half carat (.47CT to .52CT) diamond in the VS clarity range and with a 1.65 mm wide shadow band. For a larger diamond, please contact us directly. Available in whole, half, and quarter sizes 3 – 9.5. Other sizes available upon request.

This bridal set is artisan-crafted to your order in the U.S.


When you use our ring sizer prior to our making your ring, we guarantee your fit. You may order the sizer before you order your ring. Or when you order your sizer at the time of your ring order, we’ll hold your order until you confirm your size by email. 

Once you’re used our sizer, if we deliver your ring, and it does not fit, we pay for the round-trip shipping for your free ring resize or replacement within the U.S. and provide a discount for overseas shipping.

There are two ways to request our sizer:
1. Order your ring sizer for a modest fee before you order your ring(s): Order your ring sizer here.
2. Request a sizer as part of your order at the time that you order your ring(s), and we will hold your order, send your sizer, and wait for an email from you with your size(s).
In either case, we will mail a ring sizer to you promptly. This is a physical, plastic set of rings in whole and half sizes that you can play with until you are certain you have a correct size. And if you find one plastic ring is too big and one is too small, we can make a quarter size for you. Please follow our included instructions for best fit.

Our blue diamonds are white diamonds treated with heat to produce a brilliant blue color. They have VS (high) clarity, are available in a variety of carat weights, and they are very beautiful. They are not certified, and they are not covered by our one free year of loss protection for white diamonds. We recommend insuring your ring through your homeowner’s policy or Jewelers Mutual Insurance. We regret that we are unable to offer untreated, natural blue diamonds, as we do not have a reputable source for them. 

Blue diamonds, even the treated ones we carry, are tricky to find. When you order a blue diamond ring, we will begin the search for the blue diamond that we will hand-select for your ring. Please allow 6-8 weeks for delivery of your blue diamond ring. 

Making the Shadow Band to go with your Puzzle Ring
Please be advised that we will need to pick up and retain the engagement ring while we make the shadow band to fit perfectly with the puzzle ring. Allow four weeks for the creation of the shadow band. If you live overseas, we can work with you to deliver both rings together, but if you are in the U.S. please allow us to deliver the puzzle ring first and then pick it up.
