This listing does not include center stone. I would recommend this setting for a stone that is at least 7mm, changes in size of center stone will result in different pricing so please contact me for a custom quote, we can make this for your cushion or round shaped stone or can help you source a stone. I think this would look amazing with a colored stone or even a moissanite as well.
The ring on the photos had a 9.8mm cushion diamond of warm color that we bezeled in yellow gold to accent the natural color of the stone, but we can make the ring in all platinum, 18k yellow or 18k rose gold, price is the same for either metal.
Ring pictured measures 25mm or 1 inch north - south, with approximately 1 carat of G-H VS european cut melee. This is a hefty ring at around 10 grams.
