A Guinevere engagement puzzle ring set with a one-half carat blue diamond is resplendent in platinum. A Celtic knotwork inspired puzzle ring weave suggests the connection between the two of you and the love that grows deeper throughout your marriage.

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 puzzle 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 puzzle ring in platinum with a half carat (.47CT to .52CT) diamond in the VS clarity range. Please contact Mandira directly for a blue diamond of another size. Available in whole, half, and quarter sizes 3 – 9.5; other sizes upon request.

Your diamond is guaranteed to sparkle and look gorgeous on her hand.

Select your weave: The Guinevere diamond puzzle ring on this page has a tight weave. You may choose an open or standard weave for your puzzle ring, if you prefer. 

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

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.
