Pink Tourmaline Tourmalines come in a wide range of colors, from red, pinks and peach to green, yellow and blues. Pink tones are caused by trace elements of manganese present in the soil as the tourmaline was forming. In the 1890s, California was a major source of pink tourmaline, most of which was exported to China as it was the favorite color of the Dowager Empress Tz'u Hsi. Tourmaline is an October birthstone, as well as the 8th wedding anniversary stone.

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.

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.

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.

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.
