Raising the Bar
Fact, Fiction, and Fine Jewelry: The Truth About Gold

Before choosing the metal for your custom design, it is helpful to understand what we mean by "pure gold" and how karat weight works.  Pure gold—commonly referred to as 24-karat (24K) gold—is 100% gold, entirely unmixed with any other element. While undeniably beautiful and rare, its natural state is exceptionally soft. To craft fine jewelry that is durable enough for daily wear, we must alloy (mix) pure gold with other strengthening metals, such as silver and copper.  The karat number simply indicates the ratio of pure gold to these other metals.  The higher the karat, the greater the percentage of pure gold in the piece.

​24K Gold (100% Pure Gold)

  • ​Pros: The ultimate in pure gold; boasts an incredibly vivid, rich orange-yellow color; completely hypoallergenic; holds the highest intrinsic metal value.
  • Cons: Exceptionally soft and pliable—in fact, it is soft enough to mold and shape with your bare fingers. Because of this, it is easily bent, dented, and scratched, making it structurally unsuitable for holding tension or safely setting diamonds and gemstones for everyday wear.

​​22K Gold (91.6% Pure Gold)

  • ​Pros: Features a breathtakingly deep, warm yellow hue; highly hypoallergenic; holds excellent intrinsic value while being slightly stronger than pure 24K.
  • Cons: Still very soft and easily scratched or misshapen with regular use. Because of its high purity, 22K jewelry requires mindful, gentle wear and meticulous care to preserve its shape and ensure that any valuable gemstones remain perfectly secure over time.

​​18K Gold (75% Pure Gold)

  • ​Pros: The premium standard for luxury bespoke jewelry; features a stunning, rich, warm yellow hue; highly hypoallergenic and excellent for sensitive skin; holds its value beautifully.
  • Cons: A higher investment cost than 14K; the higher pure gold content makes the metal slightly softer, meaning it may show surface scratches more easily with heavy, daily wear.

​​14K Gold (58.3% Pure Gold)

  • ​Pros: The gold standard for everyday fine jewelry; offers a master-level balance of durability, structural strength, and beautiful color; the ideal choice for engagement rings, active lifestyles, and securing precious gemstones.
  • Cons: Because it contains a higher percentage of strengthening alloys to achieve its durability, the yellow color is not quite as deep or buttery as higher karat options.

​​10K Gold (41.7% Pure Gold)

  • ​Pros: Highly durable and resistant to scratches; the most budget-friendly option.
  • Cons: Features a paler yellow color compared to higher karats. Because it contains such a high percentage of alloy metals, it is significantly more brittle, meaning it is more likely to fracture or break under stress rather than bend or dent. It is also the most likely karat to trigger skin irritation or metal allergies.

​Understanding Gold Manufacturing:
​Solid, Hollow, Filled, and Plated

​When shopping for jewelry, the karat is only half the story. How the gold is applied or manufactured drastically impacts the piece's lifespan, repairability, and price. At JMD, we exclusively craft using solid gold for our bespoke commissions, but it is important to understand the differences across the wider jewelry market.

​​Solid Gold

​This means the piece is crafted entirely from a solid gold alloy (whether 10K, 14K, or 18K) all the way through. It is the gold standard for fine jewelry.
  • Pros: It is a generational investment. Solid gold will never rub off or flake, and it can be resized, soldered, repaired, and repolished by a master goldsmith over a lifetime of wear.
  • Cons: Because it uses the maximum amount of precious metal, it is the most expensive option.

​​Hollow Gold

These pieces are made from real gold, but the inside of the item is left completely hollow to reduce the amount of metal used. It is very common in thick gold chains or large hoop earrings.
  • Pros: Provides a heavy, chunky, luxurious look for a fraction of the cost; very lightweight and comfortable on the ears or neck.
  • Cons: The thin walls of hollow gold are highly susceptible to denting and crushing. Once a hollow piece is crushed, it is incredibly difficult—and often impossible—to repair back to its original shape.

​​Gold Filled

Gold filled jewelry features a substantial layer of real gold that is mechanically pressure-bonded to a base metal core (usually brass or copper) using intense heat.
  • Pros: Contains up to 100 times more gold than standard plating. It is a highly durable and affordable option for fashion jewelry that will not wear off quickly.
  • Cons: Because the core is a base metal, a master jeweler cannot cut, solder, or resize a gold-filled ring without exposing the brass underneath, which ruins the piece.

​​Gold Plated & Vermeil

Gold plating involves dipping a base metal into a chemical bath and using an electric current to bond a microscopic, flash layer of gold to the surface. When gold is plated specifically over Sterling Silver, it is referred to as Vermeil.
  • Pros: Extremely budget-friendly, making it a great option for trendy, seasonal fashion jewelry.
  • Cons: The gold layer is microscopically thin and will inevitably rub off with regular friction, water exposure, or skin oils. Once the plating wears away, the exposed metal underneath will often tarnish or turn the wearer's skin green.

Beyond Yellow: The Alchemy of Gold Colors

​Nature only makes gold in one color: yellow. Every other color of gold you see in jewelry is the result of a specific metallurgical recipe. By mixing pure 24K yellow gold with precise combinations of other metals, a master goldsmith can completely alter its final hue while simultaneously giving it the strength required for daily wear.

Here is how the different colors of gold are created:

​​Yellow Gold

​To preserve gold’s natural, sun-lit color while making it durable enough for jewelry, pure gold is alloyed with a balanced mixture of silver and copper. The higher the karat, the deeper and richer the yellow hue will be.

​White Gold

​White gold is created by "bleaching" the natural yellow color of pure gold using a precise blend of white metals, such as nickel, palladium, or zinc. Because it always originates from naturally yellow gold, raw white gold naturally possesses a beautiful, warm champagne-grey hue rather than a stark, bright silver-white finish.

​Rose Gold

To achieve this romantic, warm pink hue, pure gold is alloyed with a high percentage of copper (and just a touch of silver). Because copper is a highly durable metal, rose gold is actually slightly stronger and more scratch-resistant than white or yellow gold. It never requires plating and maintains its beautiful color forever.

​Green Gold

Green gold is created by alloying pure gold with pure silver (and occasionally a trace amount of zinc). It does not look neon green; rather, it has a beautiful, subtle greenish-yellow tint. It was highly popular in antique jewelry and is still used today by master jewelers to create subtle color contrasts, like crafting the leaves on a custom floral ring.

​Purple Gold

​Purple gold is a fascinating metallurgical anomaly created by alloying pure gold with aluminum. However, this specific combination creates an intermetallic compound rather than a standard alloy. This means the resulting purple metal is stunningly beautiful, but it is as brittle as glass. If struck, it will shatter. Because of this, purple gold can never be used to forge a ring's structural bands or prongs; instead, it is often faceted and set into a piece just like a gemstone.

​​The Myth of Rhodium Plating

Interestingly, rhodium plating was originally just a retail shortcut—it was never intended for jewelry that a customer would actually wear. By electroplating their inventory with Rhodium (a bright white metal in the platinum family), commercial jewelers could keep their pieces looking pristine under hot showcase lights for months without the need for constant, daily polishing.

Unfortunately, the industry turned this temporary display hack into a consumer standard. When you plate a ring meant for daily wear, that microscopic layer inevitably wears off unevenly due to natural friction, water exposure, and skin oils. This creates a patchy, flaky discoloration as the warm white gold underneath begins to peek through the stark white plating. To fix this, you are forced into an endless cycle—and the annual expense—of having the ring chemically stripped and "re-dipped."
​
At the master level, we approach white gold differently. Raw white gold, when properly alloyed and finished with a true, master-level polish, possesses a breathtaking, pristine brilliance entirely on its own. By skipping the artificial plating, your ring maintains its authentic, natural beauty, never suffers from flaky discoloration, and completely frees you from the unnecessary annual expense of re-plating.
