This is one of my favourites. Shame it's a devil to make!
I have the stones specially cut to fit this design and they are shaped to follow the contours of the ring.
The silver shank has triangular windows cut into the top and sides.
These replicate the bottom or 'pavilion' of the stone which also forms a triangle.
The stone itself is set in 9ct gold.
