The round is the most common type of brilliant cut and falls into the same category as the heart, oval, marquise, and pear. Many diamonds are round cut. All brilliants feature at least 57 facets and are known for their incredible fire and sparkle. This three-stone cluster ring is loaded with sparklers, including round, prong- and bead-set diamonds, and round channel-set diamonds for a luminous look. From Affinity(R) Diamond Jewelry.
