Solid Australian Boulder Opal, Free Form Cabochon, Beautiful Green and Blue Swirls (Slightly lighter color than photo).

I carefully selected this beautiful gem for my own collection in the 1990's, directly from Australian opal cutters. Priced below wholesale.

"Boulder opal consists of concretions and fracture fillings in a dark siliceous ironstone matrix. Opal is a hydrated amorphous form of silica; It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock.

Boulder opal is found sporadically in western Queensland, from Kynuna in the north, to Yowah and Koroit in the south. Opal is the national gemstone of Australia, which produces 97% of the world's supply.

The internal structure of precious opal makes it diffract light; depending on the conditions in which it formed, it can take on many colors. Precious opal ranges from clear through white, gray, red, orange, yellow, green, blue, magenta, rose, pink, slate, olive, brown, and black. Of these hues, the reds against black are the most rare, whereas white and greens are the most common. It varies in optical density from opaque to semi-transparent.

The word opal is adapted from the Roman term opalus, However, most modern references suggest it is adapted from the Sanskrit word úpala. The term first appears in Roman references around 250 BC, at a time when the opal was valued above all other gems. The opals were supplied by traders from the Bosporus, who claimed the gems were being supplied from India.

Opal is considered the birthstone for people born in October or under the signs of Scorpio and Libra." (Wikipedia)

Additional policies

I specialize in creating original contemporary art jewelry using labor-intensive classical techniques. I combine original cloisonné enamels with precious metals and precious and semi-precious gemstones, using hand fabrication, bezel setting, 22 karat gold granulation, 18 karat and 14 karat gold, and sterling silver.

In my granulated jewelry I draw on the tradition of the Etruscans and ancient Greeks. Hundreds of tiny balls of 22 karat gold, as small as .016 inches, are arranged one-by-one into intricate patterns. The granules are fused without the use of solder to a base of 22 karat gold. One moment too long in the intense heat of the torch and the entire piece melts. One moment too little and the granules feel to fuse to the base. Consummate skill and experience are required to gauge the exact moment; hours of painstaking work hang in the balance with each piece that it is created.

The effects possible with the technique of cloisonné enameling are particularly appealing. Luminous multicolored depths of the cloisonné beautifully enhance the rich effects possible with granulation in 22 karat gold, and I combined the two whenever I can.

Cloisonné is a French term which refers to cells of colored enamels separated by thin strips of metal. Each cloisonné painting is started by bending thin ribbons of pure gold and arranging them on edge to create the linear elements of the design. I use my original drawings as diagrams. The resulting cells are wet packed with grains of enamel using a tiny paintbrush. The pieces dried and then fired in a preheated kiln at 1200–1500°F. Up to 20 firings can be required to refine and develop the many layers of enamel colors. The enameled piece is then ground and polished like a fine gemstone. It is framed in a custom-made setting, using hand-fabrication, hand-forging, lost wax casting and other techniques, often enhanced by precious or semi-precious gemstones.

I am a lifelong artist. I studied fine art at Yale and have an extensive professional background in visual design. I studied 22 karat gold granulation, cloisonné enamel, and a number of other techniques under the direction of some of the best master goldsmiths and enamelists in the country. My work has been featured in numerous juried exhibitions, the best galleries nationwide, public and private collections, and won awards for many years. Each piece is designed to be worn and give enjoyment for years.
