Gold-Filled Jewelry
14k gold-filled jewelry is made by bonding a layer of 14-karat gold to a base metal core, usually made of brass or copper. The process of making gold-filled jewelry involves heat and pressure bonding, which creates a permanent bond between the gold layer and the base metal core. This results in a durable and long-lasting piece of jewelry that has the look and feel of solid gold, but at a more affordable price.
It's important to note that gold-filled jewelry is not the same as gold-plated jewelry. Gold-plated jewelry has a much thinner layer of gold and is not as durable as gold-filled jewelry. With proper care, gold-filled jewelry can last for many years and is a good option for those who want the look of solid gold without the high price tag.
Care: Wipe with a soft cloth after wear. For deeper cleaning, use a mild soapy water and soft toothbrush.
Argentium Silver
Argentium silver is a modern sterling silver alloy that contains a higher percentage of silver and a small amount of germanium.
Traditional sterling silver is an alloy made of 92.5% silver and 7.5% other metals, usually copper. This composition is denoted by the hallmark "925". Argentium silver is available in several grades. I use “940” which contains 94% silver. The remaining percentage is primarily germanium, with some copper.
Argentium silver offers several advantages over traditional sterling silver including:
Argentium silver is more resistant to tarnish than .925 sterling silver thanks to the presence of germanium, which forms a protective oxide layer on the surface.
Argentium silver is generally stronger than traditional sterling silver, making it more resistant to scratches and deformation.
Argentium silver is more hypoallergenic than traditional sterling silver because of its reduced copper content, making it a better option for those with sensitive skin.
Argentium silver has a slightly brighter and whiter appearance compared to traditional sterling silver.
