Silwer
Wat is Sterling Silwer?
Suiwer silwer is relatief sag en smeebaar, en maklik beskadig—nie geskik vir juweliersware nie. Om teen vervorming of vernietiging te verdedig, silwer word met ander metale gekombineer om dit meer duursaam te maak. Sterling silwer is die mees algemene allooimengsel wat in juweliersware voorkom. Dit moet ten minste wees 92.5% suiwer silwer, maar die ander 7.5% kan enige metaal wees. Tipies, hierdie legering is koper. Eeue van eksperimentering het getoon dat koper silwer se beste metgesel is, sonder om sy pragtige kleur te beïnvloed. The small amount of copper added to sterling has very little effect on the metal's value. In stede van, die prys van sterling silwer word beïnvloed deur die arbeid wat betrokke is by die maak van die item, die vaardigheid van die vakman, en die ingewikkeldheid van die ontwerp. Ook, jewelry made with sterling silver is often plated with rhodium to give it a bright white finish that is a bit more resistant to scratching.

History And Hallmarks
Making jewelry and currency out of sterling silver has been a practice for a very long time—since around the 12th century to be more accurate. Silver coins from this era were referred to as “Easterlings,” especially in the cattle markets. Eventually, the name was shortened to “Sterling” which is now used to denote the highest grade of silver. Fondly referred to as “the metal of the moon,” because of its milky white and greyish color, sterling silver is commonly stamped with what’s known as a hallmark. The hallmark indicates the amount of pure silver content, en dui soms die datum van voltooiing en land van herkoms aan. En onder federale wetgewing, it must be accompanied by a maker's mark or registered trademark. Acceptable quality marks for sterling silver include:
