Blue Topaz The name Topaz can be traced back to the Sanskrit word topas or “fire.” Topaz come in colors including brown, blue, green, yellow, orange, red, pink, and purple as well as colorless. Natural blue topaz is very rare and is caused by atomic element changes in the crystal structure of the stone itself. Colorless topaz is widely available and can be treated to give it a blue color. Topaz is a November birthstone.

Citrine Citrine, a yellow to orange variety of quartz, is rare in nature. A November birthstone, as well as the stone marking the thirteenth wedding anniversary, citrines are one of the most popular yellow gemstones. Often identified with the Victorian era, citrine’s use as a gem dates back to 300 B.C.

Peridot Peridot was originally mined by ancient Egyptians who called it the “gem of the sun.” Peridot ranges from brown-green to yellowish green to pure green. The Romans called peridot the “emerald of the evening” and the deepest green peridot have been mistaken for emeralds for centuries. Peridot is the August birthstone and the 15th anniversary stone.

Step Cut A Step-cut, which includes emerald and baguette-cuts, is a rectangular cut with faceting in steps. This style highlights the clarity and color of the stone. The Princess Cut features a straight sided rectangular outline with brilliant style faceting - a mix between step cut and brilliant cut. The "Calf's Head" is a less common step cut that resembles a triangle with the cut corners, thought to resemble a calf's head.

Bulgari Founded in Rome in 1884 by Sotirios Voulgaris, who changed his name to Bulgari, the company continued to expand after World War 2 with the introduction of its renowned Serpenti collection of bracelet-watches. During the 1950s and 60s Bulgari continued to make its name for use of multi-colored stones, creating pieces for Elizabeth Taylor, Ingrid Bergman and Gina Lollobrigida. Today the house continues to be known for angular forms, strong colors, cabochon gems and enduring collections such as Serpenti and Parentesi.

Ruby Ruby is called “the king of gems” in Sanskrit. Rubies have obtained the highest per-carat price of any colored stone. Ruby is a variety of corundum, a mineral species that also includes sapphire. Rubies range from orangey red to pure red to purplish red. Trace elements of chromium cause ruby’s red color. Ruby is the July birthstone and the stone for the 15th and 40th anniversaries.

Round Brilliant-Cut The Round Brilliant Cut dates back to 1919, when Marcel Tolkowsky calculated a formula for proportional diamond design to maximize fire, brilliance and wearability, published as “Diamond Design: A Study of the Reflection and Refraction of Light in Diamond.” A round brilliant diamond can also be called a full cut diamond if it features the cutting standard of 57 or 58 facets.

White Gold White Gold use in jewelry is first associated with Art Deco, as yellow gold was out of fashion and it is an alternative to platinum, which had become increasingly more expensive after 1915. 18K gold is softer than platinum but has more than enough strength for everyday wear in fine jewelry, particularly in earrings, bracelets and necklaces.

Demi-Parure Demi-Parure are pieces of matching jewelry that are designed to be worn together, though fewer than a full set or parure; dates from the second half of the 16th century, and traditionally, when a parure involved six or seven pieces, a demi-parure was a three-piece suite of (usually) a necklace, earrings, and a brooch.
