A striking marquise black diamond on a medium, four-band puzzle ring is the ultimate chic. Black diamonds are usually paired with a white metal such as platinum, shown; you may choose from 14K gold colors or combinations, as well.

A working puzzle ring, styled after legendary Celtic knotwork rings, this ring comes apart and goes back together easily with the animated and video instructions we provide under the link below. 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 stone that you select, its very shape and size, so your puzzle ring will be a true, one-off original.

The price on this page is for this ring with a AAA grade diamond between 0.58 and 0.72CT (0.50CT shown). We will get you the biggest and best diamond available in that range. Marquise black diamonds are often quite short and wide, but we usually look for longer and narrower; we will therefore aim to select the diamond that has the closest shape to the one shown. A smaller carat weight with a longer length is more desirable and more valuable, but black diamonds are tricky to find in any configuration, so we cannot promise exactly what the best available will be like. However, we will communicate with you about available black diamonds, so you will have a say in the one placed in your ring.

If you would like this ring with a smaller black diamond (1/3CT to 1/2CT) or a larger one (0.75CT to 1.00CT) please contact us.

Certified black diamonds: Usually certified black diamonds are larger and at a higher price per carat. Please contact us if you would like us to locate and price this ring with a certified black diamond.

Sizes: Available in whole, half and quarter ring sizes from 3 – 10.5.  Other sizes are available upon request.

Shown is an open weave which means the ring is wider at top center, irrespective of diamond length. You may select a standard or tight weave if you prefer.

The marquise black diamond puzzle ring is artisan-crafted in the U.S. and is exclusively offered 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.

  1. I bought this ring in January of 2019 for my now fiancée, and it is amazing, to say the least. I worked with Mandira for a few weeks on getting everything perfect, and she really helped me through the whole process. I was skeptical about buying a ring online that I was not going to see before, but she helped ease my mind with how professional she was and she answered any question that I had. Once I received the ring I was just amazed at how perfect it was. My fiancée gets so many compliments on the ring, and she absolutely loves it. We will definitely buy from Crystal Realm again in the future.
