1 1/2 ct oval cut diamond

This is a classic engagement ring with the center diamond flanked by two trillion (triangle) shaped diamonds of G-I color and SI clarity. As the size of the center diamond increases so does the size of the trillions, graduating from .13 ct each for a 1/2 ct center diamond to .56 ct each for a 3 ct diamond. 

The same style ring will take most popular diamond shapes such as round, oval, pear, marquise, emerald, and princess cut.  It is available in 14k white or yellow gold, 18k yellow gold and platinum in a stock size 7 that can be resized easily.
