12.70 Carat Simulated Ruby and 1.20 Carat CZ Necklace in Sterling Silver. 18"

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."

POPCORN: A lightweight, tubular chain with a beaded texture created by convex links.

LADDER: An old-fashioned clasp used for watches. With one end-piece resembling a two-spoke ladder, the foldover side can be hooked into one of two slots to adjust size.

FIXED: A bale that is worked into the actual design of a pendant. Typically seen in slide pendants.

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

CUSHION: A gemstone that features a rounded square shape. The facet arrangement can be either a type of modified brilliant cut or a checkerboard pattern.

CUBIC ZIRCONIA: once called the poor cousin to the diamond, CZs have since become a fashion statement in their own right. Perfect for travel and a little extra bling, CZ Jewelry is one of man's flawless creations.

TRILLION: A variety of the modified brilliant-cut, sometimes called "trilliant" or "trillian." Features a faceted triangular shape, sometimes with curved edges.
