Our oval 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 oval center creating an elevated design element to that of the classic engagement ring style. A superbly cut and symmetrical oval center stone gives a flattering illusion of length to someone's hand and fingers, and is beautifully showcased in this cathedral design. The oval center stone is set in a very durable die struck, six prong head. Your center stone is secure and well protected while also 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 of our oval cathedral solitaires feature the finest high quality, hand cut and hand polished Russian formula lab grown diamond look cubic zirconia, cut to exact mined diamond specifications. These oval cathedral solitaires are available in a vast selection of carat size center stones, as well as various precious metals like 14k and 18k solid gold and platinum. See below for the detailed features on this classic oval diamond look solitaire engagement ring and why people turn to Ziamond for the best lab grown diamond simulants with a lifetime guarantee.

    I was very pleasantly surprised at the quality of my purchase. I had previously had experience with czplatium, and was very unhappy with the service, and quality of my purchase. The rings I have purchased from your company I will wear with pride and joy!

    This ring is my Christmas gift for 2010. It's absolutely stunning, and I love how it looks on my finger. This is my third piece from Ziamond, and I know it will not be my last. Thanks again for great customer service, and a beautiful product.
