Turquoise and 2.50 ct. t.w. Multi-Stone Ring in Sterling Silver. Size 9

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."

RHODOLITE: Rhodolite charms in a range of feminine shades — from rose to raspberry to purplish-red. Lighter than a ruby, rhodolite garnets offer a lovely, romantic look. Rhodolite can be a delightful twist on the traditional January birthstone.

PEAR: Similar to the outline of a pear fruit, this is a round shape that comes to a point on one side.

MARQUISE: An elliptical shape that comes to a point at the top and bottom. Sometimes referred to as a "navette."

TURQUOISE: Typically polished and featuring a cabochon cut, turquoise is prized for its depth of color and the visual interest found in veins of matrix stone. Prized as a gemstone for 1000's of years, legend holds that turquoise has protective qualities.

OVAL: An elliptical shape that resembles an egg.

CABOCHON: A style of cutting gemstones to achieve a smooth, domed surface with an absence of facets.

TOPAZ: Available in a stunning selection of shades, the topaz's sky blue hue is one of the most popular colors for jewelry designs. Once thought to offer protection, today topaz is favored for its durability and affordability. Yellow topaz is the birthstone for November while blue topaz is for December.
