Ryan Cole, a jeweler at D Cole Jewelers on Exchange Street in Portland, uses Matrix 8, a 3-D CAD program as he works on a computer to design a custom wedding ring by incorporating diamonds from a family heirloom.
This 1.51-carat, round, brilliant, excellent cut and near colorless diamond sparkles like a $11,600 diamond should, according to Cole.
Using a watchmaker's loupe, Cole inspects the finished diamond solitaire ring.
Cole uses a stereo microscope to do very fine adjusting to a diamond ring he recently made by inserting a 3/4-carat diamond into a solitaire setting and bending the prongs to retain it.
Cole bends the prongs on a solitaire setting so it will hold the 3/4-carat diamond.
