Large rhinestones usually refer to diamonds of F, G, H and I grades. These grades of diamonds are very white and contain a small amount of nitrogen impurities, which makes the diamonds appear very clear and transparent, and orderly cutting makes the diamonds more shiny. These diamonds are relatively expensive and are usually suitable for buying high-grade jewelry or for high-end customization.

On the other hand, a big diamond has a very famous definition, which is a big drop-shaped diamond. This kind of diamond first rose in 1950s, and was widely used in all kinds of jewelry by designers because of its unique shape and rounded curve. The size of large rhinestones is usually 3-4 obvious grades larger than that of round diamonds with the same weight, which puts forward higher carving requirements for craftsmen.

In addition to the above two definitions, large rhinestones are often used as advertising tools in business culture. In the field of marketing and promotion, large rhinestones can represent unparalleled high-grade, gorgeous and unique feelings, and are usually used to promote high-end luxury goods, tourist resorts and quality services to attract wealthy consumers who pursue dignity.
