Bronze, sterling silver and copper necklaces. CosmicDeva Metal Art Jewelry is designed and handcrafted using environment friendly recycled metals.
Bronze for example is such a fantastic versatile metal - I love it ! It's an alloy made of copper and tin, has a beautiful warm golden tone, and is an affordable alternative to 10 or 14k gold. Solid bronze is durable, easy to clean, and will last for decades.
CosmicDeva Silver Jewelry is designed and handcrafted of .999 Fine Silver and .925 and .960 Sterling Silver using environment friendly recycled silver.
Copper was used by even the oldest civilizations on record, dating back over 10,000 years. In the earliest cases, the copper items were mined and pounded, hand-worked into shape; by 500BCE there is evidence of smelting.
I am committed to environmentally-conscious atelier practices, such as recycled metals and using less-toxic chemical alternatives for my metal- smithing work. My handcrafted jewelry does not have the same look as machine-made jewelry. Small imperfections and slight differences from the pictures may occur. It is the character of handmade and not a fault.
About Copper And Bronze:
Bronze/ Copper: these metals may discolor the skin green. It does not apply to everybody but please be aware that this might happen. I do seal all bronze and copper pendants but sealing might wear off after a certain time and need to be re-sealed. Sealed metal does not oxidate.

What is Metal Clay?
Metal clay is a crafting medium consisting of very small particles of metal such as silver, gold, bronze, or copper mixed with an organic binder and water for use in making jewelry, beads and small sculptures. Originating in Japan in 1990, metal clay can be shaped just like any soft clay, by hand or using molds. After drying, the clay can be fired in a variety of ways such as in a kiln, with a handheld gas torch, depending on the type of clay and the metal in it. The binder burns away, leaving the pure sintered metal. Shrinkage of between 8% and 30% occurs (depending on the product used). Alloys such as bronze, copper, .999 fine silver, 925- 960 sterling silver, and steel also are available.
Investment grade, or fine, silver is 99.9 percent (.999) pure or better. The Silver Maples produced by the Royal Canadian Mint are 99.99 percent (.9999) pure silver. But pure silver has some qualities that can be undesirable in particular applications. It is soft and bendable, and oxidizes easily producing a tarnish. Jewelry makers and other users of silver often mix silver with other metal to make it more suitable for their purposes. Silver of between 92.5 percent purity and fine is called sterling silver.
The standard content of sterling silver is 92.5 percent (.925) silver and 7.5 percent copper. The presence of the copper increases the hardness of the alloy, making it less likely to bend. It also slows down the rate of oxidation so silver jewelry and flatware doesn’t tarnish as quickly as fine silver. Sterling silver is usually identified with a marking of “925” or “ster” on the bottom or rear of a sterling silver piece.
Sterling Silver 950 is the purity of the silver after firing; 95% silver and 5% copper. The ACS950 will be hallmarked as Sterling silver 950ST
Our sterling silver is hallmarked with .925, .950st or .960st sterling silver.

WHAT IS NOT CONSIDERED STERLING SILVER:
- GERMAN SILVER/NICKEL SILVER: This type of metal is NOT sterling silver at all. It is a metal made up of different alloys usually, nickel, copper, zinc and sometimes lead and tin. It has the appearance of silver.
- TIBETAN SILVER: Many consumers are confused about this metal. Genuine Tibetan silver is just sterling silver that is handcrafted by an ethnic group; the Nepalese/Tibetans. Tibetan silver is an alloy of some silver, with lots of copper or other base metal.Tibetan silver is used primarily in jewelry components, and is similar to pewter – an alloy of copper, and sometimes tin or nickel, with a small percentage of pure silver.
- PALLADIUM: A form of platinum with much of the same properties and characteristics of platinum but cheaper to use.
- RHODIUM: Another form of platinum that can be applied to base metals(brass, copper), sterling silver, gold or other metals. Rhodium plating is very, very expensive.
- PLATINUM: Used in almost pure form for jewelry making. It is a very expensive metal -20% more than gold itself. It is a very strong and durable metal. (My favorite metal, just can't afford it!!!! LOL!)
- TITANIUM: The hardest natural metal in the world. Cannot be soldered. Often used in men's jewelry.
- TUNGSTEN CARBIDE: Another silver looking metal: it is scratch resistant and durable. Does not require polishing to maintain its shine.
- STAINLESS STEEL: Gaining in popularity for use in jewelry. Stainless steel is not that expensive compared to sterling silver, platinum, rhodium, argentium sterling silver or fine silver. Stainless steel is defined by 4 groups and over 150 grades. Most stainless steel used for jewelry is 308, 308l, 308lvm, 304, 304l, 304lvm. Surgical stainless steel is 316lvm.
- WHITE GOLD: A metal that combines gold with a white meal to form the alloy of white gold. The white metal can be silver, pallikium, nickel and/or rhodium plating.
- SILVER PLATE: A thin layer of silver applied (electroplated) over a base metal. The amount of silver used is negiliable.
- STERLING SILVER OR SILVER PLATE: same as above.
- STERLING SILVER OVERLAY: A thicker layer of silver applied over a base metal. The thick layer of silver allows a piece to be engraved.
- SILVERTONE: Base metal colored to look silver.
ALPACA SILVER: Alpaca Silver (Alpacca) refers to an alloy that imitates sterling silver. This bright silvery-grey metal alloy is made up of copper, zinc and nickel and sometimes iron. Alpaca Silver does not contain real silver. The term for this alloy in Mexico , Central America, and South America is Alpaca Silver rather than Nickel Silver. - In 1823 there was a contest among German & Austrian metalwork companies to develop an alloy that most closely appeared similar to visually silver. After the manufacturer, Berndorf AG, trademarked and made popular the brand name Alpacca, this term was used more frequently than the term Nickel Silver. In Germany & Austria and also in Middle and Eastern Europe the term used for this alloy is Alpacca Silver rather than Nickel Silver. It is also commonly called German Silver or Alpacca Silver. - Alpaca Silver, Alpacca Siver, Nickel Silver, and German Silver are all valued collectibles.
If you have a severe allergy to any of the metals in Alpaca silver, you may still be affected and may not be able to wear this type of silver jewelry.
So, just be careful. That $4.99 silver bracelet probably isn't sterling silver. If it is too cheap it is probably silver plated or not even that. If you have doubt, contact the seller.
- Pure. Copper is a chemical element with the symbol Cu. Atomic Number: 29. Atomic Weight: 63.546 amu (atomic mass unit).
- Cultural. The Egyptians used the ankh symbol to denote copper in their system of hieroglyphs. It also represented eternal life.
- Oldest. Copper is one of the oldest metals known to civilization, dating back more than 10,000 years. A copper pendant discovered in what is now northern Iraq has been dated to about 8,700 B.C. Its uses and contributions continue to grow.
- Natural color. Copper is the only metal other than gold that has natural color. Other metals are either gray or white.
Copper is a pure metal, not an alloy that has been used in creating jewelry for thousands of years. Its transformative qualities have been appreciated by artisans and healers alike. Left uncoated Copper can react with the acids in the skin which leave a green stain on some, this is not an allergic reaction but a transference of chelated (excreted copper) that is being quickly dissolved in the salt and acid in the sweat.
Copper is antimicrobial and doesn't harm the skin in any way. What's "antimicrobial"? An antimicrobial is a substance that kills or inhibits the growth of micro-organisms such as bacteria, fungi, or protozoan's, as well as destroying viruses. Copper is also an antibacterial as well as an antifungal agent and used in the treatment of skin disease and wounds today as it was thousands of years ago. Of course, thousands of years ago they didn't know all of this; they simply used it because it helped.
Copper is a trace element needed for healthy growth and function of bones, collagen, the brain, the heart, the skin and immune system. Copper is contained throughout our bodies and in our hair. Copper is present in our own bodies as an essential element found in all higher life forms "At lower concentrations it is an essential trace nutrient to all higher plant and animal life.
The main areas where copper is found in animals are liver, muscle and bone."

- Alloy. Bronze is a metal composed primarily of copper and tin. Copper is the main component, and brass is usually classified as a copper alloy.
- Stronger. Bronze is stronger and harder than copper and brass, but not as strong or hard as steel.
Bronze, in metallurgy, alloy of copper, tin, zinc, phosphorus, and sometimes small amounts of other elements. Bronzes are harder than brasses. Most are produced by melting the copper and adding the desired amounts of tin, zinc, and other substances.
The properties of the alloy depend on the proportions of its components. Aluminum bronze has high strength and resists corrosion; it is used for bearings, valve seats, and machine parts. Leaded bronze, containing from 10% to 29% lead, is cast into heavy–duty bushings and bearings. Silicon bronze is used for telegraph wires and chemical containers.
Phosphor bronze is used for springs. Bronze is used for coins, medals, steam fittings, and gunmetal and was formerly employed for cannon. Because of its particularly sonorous quality, bell metal, containing from 20% to 24% tin, is used for casting bells.
Bronze has long been used in art, e.g., for castings, engravings, and forgings. Bronze, alloy traditionally composed of copper and tin. Bronze is of exceptional historical interest and still finds wide applications. It was made before 3000 BC, though its use in artifacts did not become common until much later.
The proportions of copper and tin varied widely (from 67 to 95 percent copper in surviving artifacts), but, by the Middle Ages in Europe, certain proportions were known to yield specific properties.
An alloy described in an 11th-century Greek manuscript in the library of St. Mark’s, Venice, cites a proportion of one pound copper to two ounces of tin (8 to 1), approximately that used for bronze gunmetal in later times. Some modern bronzes contain no tin at all, substituting other metals such as aluminum, manganese, and even zinc.

Traditional metals used in jewelry are the “noble metals”: silver, gold and the platinum metal group (including platinum and palladium). Noble metals are so called because of their ability to withstand corrosion and oxidation and their chemical stability. Today's jewelry is more varied and versatile than ever. This is partly due to the use of new types of metals and alloys used to make jewelry.
Through the use of alloys, two or more metals or elements can be combined to give the resulting metallic substance certain properties that are different from its component metals. The primary purpose of alloys in jewelry is to give metals more desirable characteristics. For example, pure gold (24 karat gold) is too soft for prolonged wearing and would scratch easily. Most gold jewelry is either 14 karat gold or 18 karat gold which consists of gold mixed with other alloys, usually silver, nickel, copper or zinc. Sterling silver is silver mixed with alloys to make it stronger. Sterling silver is 92.5% pure silver usually mixed with 7.5% copper.
