|Whether you are looking for a diamond to set in a pendant, a pair of earrings, or a diamond engagement ring, Ritani has the perfect diamond selection for you. Each natural diamond from Ritani is certified by either the GIA or AGS, two of the most respected grading agencies in the world. Round-cut diamonds are the most popular shape, followed by cushion-cut diamonds and princess-cut diamonds. In recent years, oval-cut diamonds have skyrocketed in popularity. It's important to educate yourself on the 4Cs before shopping for a diamond. In order to get a beautiful, sparkling diamond, choose the best cut grade possible.
