Importance of 925 Sterling Silver

Buying sterling silver is a worthwhile investment as its value increases with time. What is very important though is not to be duped into buying fake 925 sterling silver jewelry. This is a serious issue because many jewelers are known to sell fake sterling silver necklaces, rings, earrings and so on.

Key Words:

925 is a short name or a hallmark found on items made with silver to signify that the item is made of silver containing 92.5% by weight and 7.5% by weight of other metals, usually copper.

STERLING SILVER is a term used to signify 925. By definition, in order to be considered sterling silver an item or piece of jewelry must have a minimum millesimal fineness of 925 or contain at minimum 92.5% silver.

GOLD VERMEIL is sterling silver that is covered in a layer of gold that is at minimum 10 karats and 1.5 microns thick.

 

KARAT is a unit of purity for gold alloys, rather than weight. The word karat is from the carob seed, which was used as balance scales to measure the weight of gold in ancient Asian bazaars. Like silver, since pure gold is too soft on its own, alloys such as silver, copper or zinc need to be mixed with gold. Pure gold is 24 karats. A unit karat of gold is equal to 1/24 part (4.1667%). The gold karat shows how many parts of gold and how many parts of other metals in a gold jewelry. The following chart shows the differences between the different karats, and also shows the percentage of gold and other metals

  

Q&A With CEO 

    • Question: How can I identify if my jewelry is 925 sterling or 14K gold vermeil?
    • Answer: All Boma Jewelry is made with 925 sterling silver. Each piece of Boma Jewelry is stamped with a “925” or “b925” hallmark.

For rings the “925” is indicated on the inside the ring band. For our gold vermeil items, a jewelry card will be included with our packaging and instructions on how to properly care for gold vermeil provided.
    • Question: Why does some jewelry make my skin itch and turn my skin green?
    • Answer: To the untrained, naked eye, fine jewelry that is made with precious metals like gold and silver can look similar to plated jewelry (which is jewelry made with a base metal like brass and coated with a thin layer of silver or gold). Over time plated jewelry can fade allowing the base metal to surface. Plated jewelry made with brass uses a combination of zinc and copper which often tarnishes, oxidizes and can turn green. Because most fast fashion and costume jewelry is cheaply made, toxic chemicals or glues might be used instead of setting stones or parts by hand and these toxins or chemicals may contribute to skin irritations and discoloration of skin.
