About silver

Silver has served as a jewelry material for more than 6,000 years, valued for its white metallic luster, workability, and relative abundance compared to gold. This page explains what silver is as a material, the alloy grades used in modern jewelry, and the reasons sterling silver became the standard for wearable pieces. SilverRush Style has worked exclusively with .925 sterling silver and natural gemstones since 2005.

What Silver Is

Silver is a chemical element with the symbol Ag (from the Latin argentum) and atomic number 47. It belongs to group 11 of the periodic table, alongside copper and gold, and shares many of their physical traits. In its pure form, silver is a soft, white, lustrous transition metal with a density of 10.49 g/cm³ and a melting point of 961.78 °C.

Three properties matter most for jewelry use:

• Conductivity. Silver has the highest electrical and thermal conductivity of any metal. While this trait drives industrial demand, it also means silver responds quickly to temperature during soldering and casting.
• Malleability and ductility. Pure silver can be hammered into sheets less than 0.0025 mm thick or drawn into wire fine enough for filigree. A single gram can be drawn into roughly 1.8 km of wire.
• Tarnish behavior. Silver does not rust or oxidize in dry air, but it reacts with sulfur compounds (hydrogen sulfide in particular) to form silver sulfide, the dark film known as tarnish. Humidity, rubber, wool, and certain foods accelerate this reaction.

Silver occurs in nature as a native metal and within ores such as argentite (Ag₂S) and chlorargyrite (AgCl). The largest producing countries today are Mexico, Peru, and China, with Mexico alone accounting for roughly 23% of global mine output. Historic European supplies came from Bohemia, Saxony, and Spain, while the Spanish colonial mines at Potosí (modern Bolivia) supplied much of the world's silver from the 1540s onward.

Types of Silver Used in Jewelry

Pure silver is too soft for most jewelry construction, so it is alloyed with other metals (usually copper) to add strength. The result is graded by the percentage of silver content, expressed in parts per thousand.

Fine Silver (.999)

Fine silver contains 99.9% silver and 0.1% trace elements. It is used for bullion bars, coins such as the American Silver Eagle, and some bezel-set jewelry where the metal needs to bend cleanly around a stone. Fine silver resists tarnish better than alloyed grades because there is no copper to react with airborne sulfur. Its drawback is softness: rings, clasps, and chains made from .999 silver bend, scratch, and lose shape under normal wear.

Sterling Silver (.925)

Sterling silver contains 92.5% silver and 7.5% other metals, almost always copper. The standard dates to 12th-century England, where it was used for coinage, and was codified by statute under King Henry II. The copper content gives sterling the rigidity needed for prongs, shanks, hinges, and chain links while keeping the bright white color of silver. Sterling is the alloy used for the overwhelming majority of silver jewelry sold worldwide, and it is the alloy SilverRush Style uses for every piece in our catalog.

Coin Silver (.900)

Coin silver contains 90% silver and 10% copper. The name comes from the practice, common in 18th- and 19th-century America, of melting down coins to make flatware and jewelry. US coins struck before 1965 used this alloy. Coin silver is harder than sterling but slightly less white, and it tarnishes faster due to the higher copper content. It is rare in modern production and is now mostly seen in antique pieces and some Native American silverwork.

Silver-Plated

Silver-plated items are made of a base metal (brass, copper, or nickel) covered with a thin electroplated layer of silver, typically 0.5 to 40 microns thick. Plating is not a silver alloy and contains no measurable silver by weight. The plating wears through with use, exposing the base metal underneath, and cannot be re-polished indefinitely. SilverRush Style does not sell plated jewelry.

Why Sterling Silver for Jewelry

Sterling silver became the dominant jewelry alloy for four practical reasons.

Durability at a usable weight. The 7.5% copper addition raises Vickers hardness from about 25 (fine silver) to roughly 70, enough to hold gemstone prongs and threaded fittings without deforming during normal wear.

Color. Sterling retains the bright reflective white of pure silver. Other white metals used in jewelry, such as palladium or rhodium-plated white gold, were developed in part to imitate this color.

Workability. Sterling can be cast, rolled, drawn, soldered, stamped, and chased using techniques that have changed little since the Renaissance. This keeps production accessible to small workshops and supports the wide range of designs available in silver, from cast Bali granulation to machine-cut Italian chains.

Cost. Silver trades at roughly 1/80th the price of gold by weight as of recent market years, making substantial pieces affordable. A sterling silver ring of meaningful weight remains in a price range that gold cannot match.

The trade-off is tarnish. Sterling will darken over time as the copper reacts with sulfur in the air, but the film is surface-level and can be removed with a polishing cloth or a silver dip. Worn regularly, sterling jewelry tarnishes more slowly because skin contact and movement keep the surface clean. For storage, polishing, and cleaning guidelines, see Care of Silver Jewelry.

Every silver piece sold by SilverRush Style is stamped .925 and made from solid sterling, paired with natural gemstones sourced for color and cut rather than treatment.
