FUN FACTS ABOUT 925 STERLING SILVER JEWELLERY

Silver has a rich history dating back 6000 years, as one of the first five metals to be discovered on the planet. From this stemmed its use in coins 2600 years agoand famously used in ‘Britannia silver standard’ silver bullion coins also. Countless other applications of silver and sterling silver span across fields such as medicine, astrology (supernova explosions), food decorations, energy sources (solar), sanitation and even Greek mythology.

Naturally, silver found its way into many jewellery collections due to its gorgeous lustre, durability and workability, but reinvented itself by combining with other metals to form sterling silver. Cue many centuries of elaborate jewellery workmanship that cover countless countries, cultures and traditions.

But what is sterling silver and why is it so versatile? What has made this alloy such a celebrated part of culture and history for so many years? Let’s find out...

 Sterling silver is actually a mixture of two metals

While you may know that sterling silver is a mixture of two metals due to the fact that pure silver is too soft to mould or set, you may not know exactly what these other metals are. Sterling silver is comprised of 92.5% silver and 7.5% of base metal.

Jewellery makers usually choose between copper or nickel as the base metal/alloy. When the alloy is made with copper, this combination allows for the perfect balance of hardness, versatility and that famous shine. 

Some silversmiths actually use nickel instead of copper. Nickel is known for its tendency to react with the oils on our skin, leaving behind a green ring mark and/or a nasty skin reaction due to a nickel allergy. We wrote in detail about tarnishing here if you want all the facts.

Know your alloy metals and always make sure you are buying the copper variant. At Aquila, we only ever use pure silver and copper. So, your favourite chunky hoops will never cause any skin irritation and will only ever look beautifully boho - wonderful news for those with sensitive ears.

... Read moreI've always been fascinated by sterling silver jewelry, not just for its beauty but also its history. Like many of you, I used to just see "S925" stamped on pieces and knew it meant "good quality," but didn't truly understand the science behind it. After doing my own research and experiencing different silver pieces, I've learned so much that I wish I knew earlier, especially when it comes to keeping my favorite items sparkling and avoiding those annoying green marks! First off, that 92.5% silver and 7.5% other metal blend is genius. Pure, 100% silver is simply too soft for everyday wear. Imagine if your delicate silver chain bent out of shape just from putting on a sweater – no thank you! The addition of that 7.5% base metal, most commonly copper, is what gives sterling silver its strength, durability, and that gorgeous luster we all love. It allows jewelers to create intricate designs that would be impossible with pure silver, making our chunky hoops and delicate pendants last. My big takeaway? Always, always try to find out what that 7.5% base metal is. I learned the hard way that some brands use nickel, which can cause skin irritation for many people (including me!) and those dreaded green marks. When I discovered that my sensitive skin reacts to nickel, I started actively seeking out jewelry made with copper alloys. It's truly a game-changer for comfort and peace of mind. It’s why I now prioritize brands that specify they use pure silver and copper, ensuring my favorite pieces are kind to my skin. Now, let's talk about keeping your 925 sterling silver beautiful. Tarnishing is totally natural due to silver reacting with sulfur in the air, but it's not a death sentence for your jewelry! I've found a few tricks that really work. For light tarnish, a soft polishing cloth (the kind specifically for jewelry) works wonders. For a deeper clean, I sometimes use a mild soap and warm water, gently scrubbing with a soft brush, then rinsing and drying thoroughly. A home remedy I love is making a paste with baking soda and a little water, carefully applying it, and then buffing it off. Always avoid harsh chemicals, though, as they can damage your silver. Storage is also super important! I used to just toss my silver into a jewelry box, but I've since learned that storing pieces individually in airtight bags or cloth pouches significantly slows down tarnishing. Keeping them away from humidity, direct sunlight, and even things like hairspray or perfume before you put on your jewelry will make a huge difference. Finally, how do you know if you're getting genuine 925 sterling silver? When I'm shopping, I always look for the "S925," ".925," or "Sterling" stamp. It’s a legal requirement in many places, signifying its authenticity. Sometimes, if a piece is very old or handcrafted, it might not have a stamp, but for new purchases, it's a must-check for me. A quick magnet test can also help – real silver is not magnetic, so if it sticks, it's likely not pure sterling! Understanding these facts has truly transformed how I appreciate and care for my 925 sterling silver jewelry. It’s not just about the sparkle; it’s about the craftsmanship, the history, and knowing how to make these cherished pieces last a lifetime.
