Item # ABD-12863

Our Avalon four-band engagement puzzle ring with a princess-cut genuine blue diamond brings a touch of Renaissance romance to her hand.

This puzzle ring, with an ultra-secure gemstone setting, is also extremely comfortable to wear, and unlike many engagement rings that hold a stone up off the ring, this one will not catch on clothing. Your 4mm gemstone rises above the puzzle at a medium height, and the prongs are rounded for safety. If she works with her hands, is a teacher, nurse, athlete, outdoors-woman, or if she prefers a ring that is far from gaudy, the Avalon is a wonderful choice.

A true four-band puzzle ring, the Avalon ring comes apart and goes back together, with only a little practice using the video instructions we provide under a tab above on this page. Treat her to a truly unique, artisan hand-woven, work of art on her finger and the fun of amazing her friends with her skill at assembly.

Your diamond size options:
Approximately 3/8ths CT (0.375 CT);  4mm square
Just over 1/2 CT or 0.55 CT;  4.5mm square, shown
Approximately 7.5/10ths CT or 0.75 CT;  4.75mm square
Approximately 1.05 CT;  5.5mm square

Diamond orientation: You may select the square orientation, as shown. Or you may select a “kite” orientation in which the corners of the diamond are oriented to N-S-E-W.

Precious metal options: The base price on this page is for this ring in 14K white, rose, or yellow gold or four colors of gold (white, green, rose, yellow). You may select platinum if you prefer.

Ring sizes: Available in whole, half, and quarter sizes 3 – 10.5; other sizes upon request.

Puzzle ring weave: You may also select your preferred puzzle weave. Shown is an open weave usually worn with an optional shadow wedding band; you may prefer a tight weave, favored for wearing with a wedding band of uniform width. There is no standard weave for the Avalon puzzle ring.

The Avalon engagement puzzle ring is artisan-crafted in the U.S. and offered exclusively by 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.

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.
