SOLO jewelry
At SOLO, I only work with 14k gold, 14k gold filled, and sterling silver, the three metals I trust most for beauty, quality, and longevity. They are the ones I wear myself, the ones that can handle being lived in, worn every day, layered, traveled with, and still look beautiful years later.
That said, people are always asking me about the difference between 14k gold and gold filled, and it made me realize how much confusion there is around all the different metals you see online. So I decided to dig in, do a little research, and teach you (and me!) more about what these metals really are, how they wear, and which ones are worth investing in.
Let’s go!
14k Gold
Let’s start with the metal everyone knows by name: gold. It is the most classic, the most recognized, and the one people associate with forever beauty, but there is a lot of confusion about what “14k” actually means.
Did you know that 14k gold is not pure gold? And that there are actually other metals, like copper, silver, or zinc, mixed in too? Do not worry. You actually want those other metals in your gold. Here is why.
Pure gold, also called 24k, is stunning in color but incredibly soft, so soft that if you made a chain, ring, or bracelet out of it, it would bend, dent, and scratch almost immediately. You could literally press your fingernail into it and leave a mark. Each tiny link in a 24k chain is so malleable that daily wear, gravity and movement, would slowly stretch and distort it. Over time, those links can elongate or kink, giving the piece a warped look.¹
That is why jewelers almost never make everyday jewelry from pure 24k gold. It is gorgeous, but it simply cannot stand up to real life.
When pure gold is combined with small amounts of other metals, like copper for warmth, silver for brightness, and zinc for stability, it becomes 14k gold. That means the piece is 14 parts gold out of 24, or about 58.3 percent pure gold. By comparison, 18k gold is 18 parts gold out of 24, or 75 percent pure gold, and 24k is 100 percent pure gold. The higher the karat, the richer and softer the metal. The lower the karat, the stronger and more resistant to scratches.
Those added metals in 14k give it structure and everyday strength while maintaining that signature buttery tone. Without them, your jewelry would lose its shape within weeks. With them, your jewelry becomes strong enough to wear every single day, through ocean swims, travel, work, and everything in between, without losing its color or shine.
That is why 14k gold is used for engagement rings, wedding bands, and chains that people wear for decades. It is still real gold. It just happens to be real gold that can keep up with your life.
14k Gold Filled
Gold filled jewelry is one of my favorite materials because it lets you have the look, feel, and lasting quality of solid gold without the price tag. I use gold filled beads and findings in my HAPPY bracelets because I want them to last while you live it up.
Gold filled means a thick layer of real gold, at least 5 percent of the total weight, permanently bonded to a base of jeweler’s brass using heat and pressure. It is not plating. The bond is permanent, and the gold layer is many times thicker than gold plating.³ That is why gold filled jewelry can be worn daily without the color rubbing off or changing.
I only source my gold filled materials from the United States and Italy, two places known for having the strictest standards in the world. They regulate the purity of the gold, the thickness of the layer, and the precision of the bonding process.⁴ The result is gold filled jewelry that is richer in tone, more durable, and simply feels better when you wear it.
It is also hypoallergenic for most people and extremely resistant to tarnish. You can wear it in the shower, at the beach, or at the gym, and it keeps its glow. For me, it is the perfect material for everyday luxury: jewelry you can truly live in.
Gold Vermeil
Gold vermeil, pronounced "ver may," is another beautiful option that sits somewhere between gold filled and gold plated. It is made from a base of sterling silver that is coated with a layer of gold that must be at least 2.5 microns thick, which is thicker than standard gold plating.⁴ Because the base metal is real sterling silver, vermeil is considered a fine metal and is generally hypoallergenic.
However, gold vermeil tends to wear down more quickly than gold filled jewelry because of how it is constructed. The gold layer is applied through electroplating, which means it sits on the surface of the silver rather than being permanently bonded to it. Even though the gold layer is thicker than typical plating, it is still relatively thin compared to gold filled jewelry.⁵
This difference in construction has a big impact on longevity. Gold vermeil can begin to show wear after a few years of regular use, especially if it is worn daily. Gold filled jewelry, on the other hand, can last decades with proper care because the gold layer is significantly thicker and more durable.
That said, vermeil can still be beautiful jewelry and a great option if you love the warmth of gold with a sterling silver base. It simply benefits from a little more care and gentler wear to keep it looking its best.
Gold Plated
Gold plated jewelry can be beautiful, but it is the most delicate of all these finishes. It is made by electroplating an extremely thin layer of gold, often less than 0.05 percent of the item’s total weight, onto a base metal such as copper, brass, or zinc alloy.⁶
It is affordable and perfect for experimenting with trendier pieces, but the layer of gold is so thin that it can wear away quickly, especially on rings and bracelets that rub against the skin or other surfaces. Once the gold fades, the base metal shows through, and those metals can tarnish or irritate the skin.
Gold plating looks great at first, but it is best for short term fashion jewelry, not long term wear, which is why I do not use it in my designs.
Sterling Silver
Sterling silver is another metal I love working with. It is clean, bright, and timeless. It has a quiet elegance that works for both everyday wear and special occasions.
Sterling silver is made from 92.5 percent pure silver blended with 7.5 percent copper for strength. That is what the “.925” stamp means.⁷ Pure silver by itself is too soft to hold its shape, but when it is alloyed with copper, it becomes durable enough for daily use.
Silver naturally oxidizes over time when exposed to air and moisture, which is what causes tarnish. The good news is that it is easily cleaned, and the more you wear it, the less it tarnishes. The natural oils on your skin actually help keep it polished!
If your sterling silver ever darkens, a quick polish with a soft cloth brings it right back. I love that silver feels lived in. It softens and reflects your daily life in such a beautiful way.
Choosing What’s Right for You
Every metal has its purpose and personality. 14k gold is forever, the real thing made to last generations. Gold filled is the perfect blend of durability and beauty for everyday life. Vermeil offers that fine jewelry feel with a touch of silver underneath. Plated jewelry is playful and trend driven. Sterling silver is cool, bright, and versatile.
The important thing is knowing what you are buying, how it is made, and what you can expect over time. I design with metals that are meant to be lived in, pieces you can reach for every day and not have to think twice about!
