Art Deco jewelry, also known as Jazz Age jewelry, became popular in the 1920s and remained in style through the 1930s. It was named after the Exposition International des Arts Décoratifs et Industriels Modernes, a exhibition held in Paris in 1925 that was largely dedicated to the jewelry arts. This style was inspired by a variety of cultural and artistic movements, such as Oriental, African, and South American art, as well as Cubism and Fauvism. Art Deco jewelry is known for its sharp, straight lines and emphasis on modernity and the machine age.
During the Art Deco era, there were significant improvements in diamond cutting techniques, which made diamonds more radiant and sparkling than ever before. This, along with increased prosperity, allowed more people to afford diamond jewelry and engagement rings. Additionally, new casting techniques made it possible to produce more intricate and detailed settings.
Art Deco jewelry was not only fashionable but also reflected the social and cultural changes of the time. The bold, modern design of Art Deco jewelry reflected the liberation and empowerment of women during the 1920s and 1930s. Today, Art Deco jewelry is highly sought after by collectors and is often featured in museum exhibitions and high-end auctions.
Onyx is a type of chalcedony, which is a variety of quartz that is characterized by its fine grain and layered structure. Onyx is most commonly found in black and white bands, and it is known for its unique color pattern and ability to be carved into intricate designs.
Onyx has been used for centuries as a gemstone and has been prized for its beauty and versatility. It was especially popular in ancient times, when it was used to create cameos, which are small, carved gemstones that feature a raised design on a background of a different color. The layered structure of onyx made it especially well-suited for this purpose, as it allowed the engraver to cut the design in one color while creating a background of another color.
The term "onyx" is sometimes used to describe pure black gemstones, but this is technically incorrect. True onyx is always banded, with alternating layers of black and white (or sometimes other colors). Gemstones that are solid black are usually made of other materials, such as obsidian or black jade.
In addition to its use in jewelry, onyx is also used in various decorative objects and as a material for carving and engraving. It is a relatively hard and durable stone, and it is often used in jewelry and other decorative items that are subjected to wear and tear.
Marcasite is a mineral that is made up of iron sulfide and has an orthorhombic crystal structure. It is known for its golden yellow color and metallic luster, but it is very brittle and not suitable for use in jewelry. Instead, what is often referred to as "marcasite" in jewelry is actually pyrite, which is also known as "fool's gold," that has been faceted to mimic the appearance of diamonds.
Marcasite has been used in jewelry since around 1700, and it is usually found mounted in silver. It has remained popular in high-quality fashion jewelry due to its attractive color and luster. In antique jewelry, marcasite can be distinguished from cut steel faux gems because marcasite is typically bead or prong-set, like a gemstone, while cut steel is usually riveted.
Silver is a white metallic element that is known for its excellent conductivity of heat and electricity. It is represented on the periodic table of elements by the symbol Ag, and it is a member of the noble metals, which are known for their excellent resistance to oxidation.
Silver is a relatively soft metal, with a hardness that is intermediate between gold and copper. It is more malleable and ductile than gold, which means that it can be easily shaped and molded into various forms. However, it is not as hard as copper, which means that it is more prone to scratches and other types of damage.
Because of its softness, silver is usually alloyed with another metal to harden it enough to maintain the desired shape and details when it is used in jewelry and other decorative objects. This helps to give it the necessary strength and durability for use in these types of applications.
Throughout history, silver has played a prominent role in the production of jewelry and objets d'art. It is prized for its beauty and versatility, and it is often used in a wide variety of different types of jewelry, including rings, earrings, pendants, and bracelets. It is also used in decorative objects, such as candlesticks, vases, and other decorative items.
