I designed this to be my own engagement ring using a Lightbox half carat lab grown diamond and custom 14k white gold solitaire setting. It is size 4. Lightbox diamonds are not graded, estimated to be G color, VVS clarity, VG/EX cut, and this one is exactly .5 carats. My total cost was somewhere between $800-900, asking $800 but accepting reasonable offers. I am not desperate to sell, so probably would need to get close to $800. If shipping with insurance isn't too pricy I will cover it. This is a really beautiful ring and will be perfect for some lucky person, but it turns out I'm a rose gold girl instead!
