METALS

The metal you select for your jewelry lays the foundation for its look, feel and function. When choosing the metal for your ring it is important to understand the differences between them.

PLATINUM

King Louis XV of France proudly proclaimed Platinum “The only metal fit for a King.” Platinum is a naturally white precious metal and a member of the noble metals which do not corrode or oxidize. Most alloys are an industry standard of 90% or 95% pure platinum with the remaining portion comprised of ruthenium, palladium or iridium which are also Noble metals. Platinum is also a hypoallergenic making it ideal for those with rare skin sensitivities to other metals. It is thirty times scarcer than gold and will not fade or tarnish overtime.

YELLOW GOLD

The unmistakable shine that has captivated mankind and fueled its desires for centuries. From the pharaohs of Egypt to the California gold rush its history is perhaps the only thing richer than its radiant color. Gold is the most malleable metal and can be hammered and rolled into very thin sheets used in gold leafing. It is also ductile and can be drawn into non corrosive wire for use in transistors and electrical connections. In its pure state gold is very soft and is unsuitable for jewelry manufacturing. In order to strengthen it for jewelry it is alloyed with other metals to allow for better longevity and superior resistance to wear. The international system of standards for gold purity is called Karatage. Pure gold is referenced as 24 karat, 14 karat is comprised of 58.3% gold with 41.7% alloys (copper, nickel, zing, and silver),18 karat is made with 75% gold and 25% alloys.

WHITE GOLD

White gold is an alloy of gold and a combination of naturally white metals that create a silvery hue with soft yellow undertones. It was first alloyed by German alchemists in the early 18th century and rose to popularity during the 1930’s art-deco era. Because of its warm white color, it is industry standard to plate White Gold with another precious metal called rhodium which gives it a brighter, even white appearance.

ROSE GOLD

Rose Gold is gold alloyed with copper to give it a luminous blush-pink complexion. In antiquity, the smelting process unintentionally left copper that caused a pink tone. This is why many early Greek and Roman texts referred to gold as having “red” color. In 1526, Henry VIII introduced England to “Crown Gold” a 22 karat gold alloyed with copper that allowed the strength for it to be used in coin circulation. This version of Rose Gold is very similar to the alloy used by our designer, Verragio, in their engagement collection. In the 19th century many Russian jewelry makers were fond of the tone and it became so popular in the country that rose gold was referred to as “Russian Gold” for decades after. At Jewelry Expo, all of our bridal jewelry styles are available in rose gold.

STERLING SILVER

Sterling Silver is an alloy of silver (92.5%) and copper (7.5%) that provides much higher durability than silver alone. While pure silver has been used in coinage for thousands of years Sterling Silver was first alloyed in the 12th century. In the Victorian era it was common belief that no food should touch your hands leading to a rise in the production of sterling silver utensils and plates. This began to influence jewelry making beginning with accessories like money clips and hair pins and eventually rings and necklaces. It remains a popular alternative to platinum and white gold in fashion jewelry to this day. While Sterling Silver can tarnish over time it is easily revived with a polishing cloth.

TITANIUM

Titanium is an element on the periodic table that is used in many industries due to its unmatched weight-to-strength ratio. Upon its discovery in 1791 it was named after the mythological titans of ancient Greece. It is hypoallergenic, very light and nearly impossible to crack but it is not as scratch resistant as tungsten carbide. It is also versatile in jewelry and can be laser engraved and inlaid with other materials.

TANTALUM

Titanium is an element on the periodic table that is used in many industries due to its unmatched weight-to-strength ratio. Upon its discovery in 1791 it was named after the mythological titans of ancient Greece. It is hypoallergenic, very light and nearly impossible to crack but it is not as scratch resistant as tungsten carbide. It is also versatile in jewelry and can be laser engraved and inlaid with other materials.

COBALT

Cobalt Chrome is a lustrous white alloy that bears strong resemblance to precious white metals at a fraction of the price. It is used in environments where extreme resistance to temperature and pressure are required including jet turbines and machinery. Because it is hypoallergenic it is also commonly used in orthopedics as cardiovascular stents. It is much harder than platinum and gold but significantly lighter then both. Cobalt Chrome is crack-resistant and very versatile. It can be inlaid with other materials and gemstones to perfect a custom look!

TUNGSTEN CARBIDE

Tungsten Carbide is a contemporary metal popular in men’s wedding bands. It is an alloy of the element Tungsten, also called Wolfram, and carbon. Tungsten Carbide exhibits a pewter-grey color in its natural state but there are many colors and textures that are applied to the surface to achieve different looks. Tungsten Carbide is 10 times stronger than gold, highly scratch-resistant and tarnish proof.

BLACK ZIRCONIUM

If you’re after a ring that is bold and daring than Black Zirconium may top the list. Zirconium is an element of the periodic table that does not react with acids, solvents or bases and most common chemicals. This makes it an ideal material for a number of applications including nuclear reactor assemblies, incendiary munitions and submarines. Zirconium is naturally silver in tone but is heated through a proprietary process that grows a harder black oxide layer at the surface. This layer is much harder and more durable than traditionally coated black rings like tungsten carbide and black titanium.

DAMASCUS STEEL

A marriage joins two people together and makes them stronger as they support one another in life. Damascus steel symbolizes marriage in being a blend of two types of stainless steel combined to form something stronger and more beautiful than they were alone. Damascus steel is crafted using ancient techniques that metalsmiths used to forge samurai swords. The two steels are heated and bonded together then folded many times eventually producing a billet of metal with unique rolling patterns likened to fingerprints.

METEORITE

Looking for something that is truly out-of-this-world? Look no further! The meteorite used in our Lashbrook rings was formed in space billions of years ago. It was discovered in Namibia, Africa in 1836 and belonged to a 171-mile-long iron meteorite that exploded as it entered our atmosphere. It is called, “Gibeon Meteorite,” named for the town nearest its resting place. Gibeon meteorite boasts beautiful striations called Widmanstätten patterns that create its unique etched look. Meteorite is a very versatile material that can be inlaid into other metal rings and can even be accented with gemstones inlays according to preference.

ELYSIUM

For a love to last “forever” Jewelry Expo is proud to offer Elysium rings. Elysium is actually solid diamond that is manufactured exclusively by Lashbrook for use in their series of men’s wedding bands. It is created using intense high pressure (1,000,000 PSI) and extremely high temperatures (2700 Fahrenheit) in a controlled environment. Because it is 100% diamond crystal it is the most scratch-resistant men’s wedding band in existence. It is also crack-resistant, hypoallergenic and very light averaging about 30 carats (6 grams) depending on which style and width is chosen.
