i just adjusted the colour of the image in a photo editing program, and added in a picture of one of my antique cut stones. it's not perfect... but it gives a much better idea of what the end product might look like, compared to their white metal/RB picture
i think a 6.5-7mm stone is a lovely size. and, especially in a warmer, antique cut, i think you can definitely go a little larger (stone-wise) than you can in a colourless, or near colourless, modern cut.
srsly, i really, really love that ring. ♥
