Buccellati

Buccellati is known for the impeccable quality of its Italian gold. Founded in 1919, it is the patriarch of haute Italian jewelry. Italian Goldsmith Mario Buccellati opened his shop in Milan, and was the first among Italian Goldsmiths to open a shop on Fifth Ave in New York and later in Palm Beach.

As his popularity gained, his clientele came to include the Vatican and the Royal Courts of Europe, leading to his nickname, “The Prince of Goldsmiths.”
Mario Buccellati drew upon the work of the Renaissance and Eighteen Century craftsman for design. The brand has cultivated a style all its own, distinguished by the use of refined techniques such as tulle, lace and honeycomb.

The house also gives jewelry a fabric effect by brushing and mattifying metals, and it often mixes silver and gold for texture and light enhancement. Dense gem encrustation gives Buccellati’s jewelry its rich texture.
The company works through a stable of nearly 300 artisans throughout Italy. The company only produces one of a kind or extremely limited editions of their pieces. It produces about 4,000 pieces per year, including handmade silver objects and watches.

Rubellite/Pink Tourmaline

There has been increased interest in fine pink tourmaline gems. A major reason is the market for pink tourmaline, like much of the jewelry industry, is driven by Chinese demand, where growing wealth has fueled an insatiable appetite for fine jewelry.

Elbaite is the most well-known and valuable form of tourmaline. Almost all of the tourmaline gemstones are of the elbaite variety.

China’s demand for pink tourmaline, and the pinkish-red variety known as rubellite, is not new. Part of this penchant for the pink stone is owed to the fact that pink tourmaline was the favorite gemstone of the Empress Dowager Tz’u Hsi of China in the late 19th century.

During the late 1800s, much of the pink and red tourmaline mined in California, where the gem was first found in 1890s, was shipped to China.
The gemstone’s popularity has pushed prices for high quality pieces to ever higher levels.
Today most tourmaline comes from Africa, particularly Mozambique, Namibia, Nigeria and Tanzania.

Tourmaline is a silicate compounded with aluminum, iron, magnesium, sodium, lithium or potassium. Tourmaline has a hardness level of 7 to 7.5 on the Mohs scale. It is extremely durable. The best tourmaline displays excellent transparency and a vitreous luster.
