The Classic Flat with Gold ring has a modernistic clean look with an inlay of 18K gold. The gold is dished out for different reflective properties. The ring can utilize your diamond or an optional Cubic Zirconia or other gemstone.   Since this ring is symmetrical, the height of the stone will determine the thickness of the ring, so smaller diamonds (below around 3mm diameter) make for more comfortable rings. The ring shown has a diamond that is about 4.5mm in diameter in a Brushed finish.
