Gem Butterflies

The incredible colours of rhodochrosite, haĆ¼yne, sphene, yogo sapphires, tanzanites, hiddenite, garnets and benitoites at the Los Angeles County Natural History Museum, in the Butterfly Broach Collection.

This brooch is almost entirely set with benitoite, the California state gemstone.
A barium-titanium silicate mineral (BaTiSi3O9), benitoite is a rare mineral, crystals large enough to be cut into gemstones are found only in one location: the Dallas gem mine in San Benito County, California. An unusual geologic setting of hydrothermal veins between glaucophane schist and serpentinite created this rare mineral. Benitoite is known for its high dispersion and its vivid blue fluorescence in UV light.
Orange spessartine garnets from the Little Three mine in Ramona, California highlight this brooch, along with colorless diamonds and green tsavorite garnets from Kenya.
The multi-colored sparkle of this butterfly emanates from its green titanites (“sphene”) from Madagascar. The "fire" of titanite derives from its high dispersion and refraction. Titanite (CaTiSiO5) is a fairly common accessory mineral in igneous and metamorphic rocks, but is seldom found in size and quality suitable for gems.

This butterfly brooch brings together titanites in three different colors: green from Madagascar, brown and yellow from Pakistan.

A 13.51ct rhodocrosite (MnCO3). This mineral is very rare in jewelry. Apatite and opal cover the wings, he eyes are green chromium-rich titanite (sphene).

Pink and red spinels from Vietnam are the highlights of this butterfly brooch. Red spinel (MgAl2O4) has long been used as an affordable alternative to ruby, which it closely resembles. Some famous historical rubies are actually red spinels. Spinel is now very popular in its own right. The eyes of the butterfly are blue jeremejevites (Al6(BO3)5(F,OH)3) from Namibia.
A 10.01-ct green hiddenite is the central piece of the brooch. Hiddenite is a green variety of the mineral spodumene (LiAl(SiO3)2) in which the color is caused by small amounts of the element. chromium. Hiddenite from North Carolina is found associated with emerald, the green variety of bery, which also owes its color to chromium. The body of this butterfly is the world's largest faceted hiddenite.
This butterfly brooch is set with blue sapphires from Yogo Gulch, Montana. Sapphire senso stricto is the blue variety of corundum (Al2O3).

Buccellati Green Beryl and Multi-Colored Sapphire Earrings
Buccellati has been well-known since the mid 1700s in the Italian Jewelry industry. The first Buccellati Jewelry house was established in 1919 in Italy by Conterado Buccellati.

Buccellati is known for the impeccable quality of its Italian gold.

18k Yellow Gold & Platinum Diamond & Ruby Bracelet
The company is the patriarch of haute Italian jewelry. Goldsmith Mario Buccellati 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 world-famous 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.
In 1965, Mario’s son Gianmaria, who designed his first piece of jewelry at the age of twelve, took over the family firm after his death. Both a gifted designer and goldsmith, Gianmaria proved to be a wise businessman as well, expanding the business by opening a number of boutiques around the world.

Today, the name Buccellati is synonymous with the finest in handcrafted gold jewelry.
The company works through a stable of nearly 300 artisans throughout Italy who are skilled in a specific technique of making jewelry. The company only produces one of a kind or extremely limited editions of their pieces.

It produces approximately 4,000 pieces per year, including handmade silver objects and watches.
