Hello Fred, sorry for the late reply. The ring you like was made to-order custom for an heirloom family diamond. We can remake the ring with any stone but it is not a stocked item. Email a picture to jon@14karats.com. He should be able to give you a rough cost estimate. thanks
The 14 Karats 
How and where can I purchase this setting?
