Item # GU-TANZ-9705

A photograph cannot show the depth of color and sparkle of this stunning tanzanite. Tanzanite is utterly gorgeous – a trichroic gemstone with three levels of color, so as you turn it, you will see flashes of blue and purple, and sometimes of orange, yellow, red, or green.

Tanzanite is the only birthstone added since 1912 to the American Gem Trade Association’s list of gemstones, so it is now an official birthstone for December and the gem for the 24th wedding anniversary. As with all of our puzzle rings, you must be over-the- moon about your gemstone and ring, or we will replace your stone with another, no questions asked (except those necessary to learn more about what you value!)

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 hand-weave your engagement ring precisely for the stone that you select, its very shape and size, so your puzzle ring will be a true, one-off original.

Your gemstone: We show this ring with a 4.5mm, 0.45CT AAA tanzanite. You may select from this and a 5mm, 0.58CT, AAA tanzanite. For a larger stone, please contact us for an individualized quote. 

Your options: The base price on this page is for this ring in palladium, and you may select from other precious metals listed below. Available in whole, half, and quarter sizes 4.5-10.5; other quarter sizes upon request.

The Guinevere puzzle engagement 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.

Guaranteed U.S. delivery: Order by Wednesday evening, any week, with FedEx Express (Two Day) shipping, and receive the engagement ring two weeks from the following Friday, i.e. Friday two weeks later. Please contact Mandira for out-of-U.S. delivery times.
