The left picture is the computer design and the right picture is the finished diamond ring.
Here's a great example of how we go from computer aided design (CAD) drawings to a finished ring. This marquise diamond is bezel set sideways with diamonds set underneath and down the sides of the ring. This is an amazing design, brought to us from our client.  She found a picture of a ring design she liked on the web and brought it to us.  The design was a marquise diamond set sideways, but with little else to really set off her diamond.  We added a bit of bling to make her center one carat stand out from the crowd.
Our client loved her new ring!
