YELLOW GOLD: Gold is a precious metal with a natural yellow color. It is quite soft and often alloyed with other metals to increase its strength. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural gold.

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."

ROLO: A chain comprised of interlocking circle-links.

LOBSTER CLASP: named after the pinching style of the hook, this clasp is often shaped like a lobster's claw. Use your finger to work the lever to open the clasp.

SIMULATED CORAL: Simulated coral is an artificial stone made to imitate real sea coral. Sometimes known as "faux coral," it does not actually hold any of the physical properties of coral, as it could be made from acrylic, plastic, or resin. Simulated coral is very affordable and can create the same look for less.
