Our emerald cut laboratory grown diamond alternative cubic zirconia cathedral solitaire engagement rings blend the traditional Tiffany style solitaire with a graceful, vaulted shank. Both sides of the shank elegantly angle upwards and approach the brilliant emerald cut center creating an elevated design element to that of the classic engagement ring style. When worn, the longer length to width ratio of the rectangular shape of the emerald cut, visually elongates your fingers and your hand. Select your choice of a brilliant 104 facet emerald radiant cut center or an elegant and understaned 27 facet traditional emerald step cut diamond look cubic zirconia center stone. The emerald cut center stone is set in a very durable die struck four prong head, ensuring that your center stone is secure and protected while allowing maximum light for brilliance. The shank of this engagement ring is slightly rounded and measures approximately 2.5mm at its widest point with a slight taper towards the bottom. Wider 3mm, 4mm and 5mm versions available via special order. The cathedral solitaire is stunningly beautiful when worn alone or coupled with a gold or platinum comfort fit band, simulated diamond band, or man-made colored stone band of your choice. The height of the cathedral shank allows for most eternity bands and anniversary bands to sit more flush against the solitaire. Each emerald cut cathedral solitaire features the finest high quality, hand cut and hand polished Russian formula lab grown diamond look cubic zirconia, cut to exact mined diamond specifications. These emerald cut cathedral solitaires are available in a myriad of carat size center stones as well as various precious metals, like 14k or 18k solid gold and platinum.

    I am impressed with the service, web site and apparent quality. I can't wait to get my rings, I am expecting them to be absolutely beautiful and of such a quality that they will be "real diamonds" in everyones eye! The professional way everything is handled there is impressive. If all continues to go this good you can bet I will be a "lifer" with Ziamond! Thankyou!!!

  • Can't stop smiling! 5

    Posted by JD on Dec 28th 2019

    My 1.5 carat solitare CZ is so beautiful! I cant stop smiling about it. It came in a very nice box and delivery was much faster than I expected for this special order item. Quality of my ring is excellent and I got compliments the first day I wore it. Will definately buy from this merchant again. Highly recommended.

  • Truly gorgeous ring 5

    Posted by Marti on Oct 14th 2018

    I ordered a 2.5 emerald cut solitare engagement ring from Ziamond. When I recieved the ring it was what I ordered, but wish I had ordered the 104 facet cut and not special ordered mine with 27 facets. Oh well, when I wear my ring I do receive many compliments and that makes it all worth while. It is truly a gorgeous ring.
