We started in CAD and designed the ring to come to an agreement on the design.  This is the rendering we agreed on.  I then printed the model from the CAD file to cast the ring. 

The 3D print right out of the printer.  The purple is support material and the blue is model material.  

This is the printed model after the support has been removed and it has been sprued and ready for investment.

We decided to cast in 18k gold.  This is 11 pennyweights of gold that was needed for the casting. 

This is the ring just after casting.

And this is the finished ring.  1-1carat diamond.  10-1.7mm diamonds, 14-1.3 mm diamonds and 2-2mm black diamonds set in 18k gold.
