Item #GUIN-BLD-16604

A Guinevere engagement puzzle ring set with a one-half carat or larger blue diamond is resplendent in platinum. A Celtic knotwork inspired puzzle ring weave suggests the intertwining of you and your beloved’s lives into one.

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

Use the video under a tab above on this page to learn to put this four-band, genuine, working puzzle ring together. Then amaze your friends and loved ones with your skill! 

Precious metal options: This page features this stunning ring in platinum. For gold and gold colors, please see a separate listing on our site. 

Puzzle ring weave: Select your weave: The Guinevere diamond ring on this page has a tight weave. You may choose an open or standard weave, if you prefer. See the options link below to help you decide on the weave you like.

Ring sizes: Available in whole, half, and quarter sizes 3 – 9.5; other sizes upon request.

The Guinevere blue diamond engagement puzzle ring is artisan-crafted in the U.S. and offered exclusively by Crystal Realm.

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 now certified (New!).

Our blue diamonds 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. The benefit of using Jeweler’s Mutual Insurance is that they cover mysterious disappearance without a police report. Homeowner’s policies tend to require a police report, even if you are certain you lost your ring when you were swimming at the lake! Jeweler’s Mutual Insurance is the same insurance company that insures just about every jewelry business in the country. They are well respected and reliable. (And no, we don’t get a cut!)

We do not offer untreated, natural blue diamonds, as we do not have a reputable source for them. We’re not wild about natural blue diamonds, anyway, even if we could find them, as they are very costly and don’t have the brilliant, intense, blue color of the heat-treated diamonds.

Blue diamonds, even the treated ones we carry, are challenging to find. When you order a blue diamond ring, we will search for your diamond and will communicate with you about how the search is going. Please allow 6-8 weeks for the delivery of your blue diamond ring. 

When you order a blue diamond ring with a shadow band, we will need to pickup and retain the engagement ring after you propose with it, so that we can mate the shadow band  to the engagement ring perfectly.

When you order a blue diamond engagement ring with another type of wedding band, the two rings may be delivered separately or together.
