STERLING SILVER: Also known as "Standard Silver," sterling silver is silver alloyed with other metals to increase the hardness and durability. Generally, sterling is 92.5% silver and 7.5% other metals. Some sterling silver jewelry is plated with 14kt-18kt gold and referred to as "vermeil," or "gold over sterling."

SIMULATED SAPPHIRE: A simulated sapphire is an artificial stone made to imitate real sapphires. Sometimes known as "faux sapphire," it does not actually hold any of the physical properties of sapphire, as it could be made from acrylic, plastic, glass or CZ. Simulated sapphire is very affordable and can create the same regal look for less.

PRINCESS: A multifaceted gemstone cut that has a square or rectangular shape with a facet arrangement that yields a similar level of brilliance to the round brilliant-cut. The princess-cut is known for the distinct "x" shape it renders while looking through the table.
