What Does Karat Mean?

Karat measures the proportion of pure gold in an alloy. While pure gold is soft and malleable, mixing it with other metals increases strength and alters the colour. Each karat denotes 1/24th of the final piece’s weight in pure gold—so a 12k piece contains half gold and half other metals. As the karat number rises, so does the percentage of gold. Lower karats contain more alloy metals such as copper, silver or palladium to boost hardness and change the hue.

In Australia, hallmarking laws require clear markings on precious metal pieces. You’ll often see stamps like “750” (for 18k) or “417” (for 10k) inside rings or pendants. These numbers help you verify authenticity and ensure you’re getting exactly what you pay for.

How many carats is pure gold?

If you’re wondering how many carats is pure gold, the simple answer is 24 carats. In jewellery terms, we write it as 24k gold—that is, 100 % gold content, free from any other metals. Its vivid yellow shine never fades, making it ideal for pieces you plan to keep for generations.

24k Gold: Pros and Cons

Pure gold has its own special appeal. We often recommend 24k gold for pieces that mark major milestones or serve as treasured heirlooms.

Pros of 24k gold

Firstly, nothing matches the warm, lustrous tone of pure gold. It never tarnishes over time, even with minimal care. Since it contains no alloy metals, it remains hypoallergenic—perfect for anyone with sensitive skin. Moreover, its status as 100 % gold means it holds maximum intrinsic value, making it popular for investment bars or cultural traditions, especially in many Asian communities.

Cons of 24k gold

However, pure gold is soft. It scratches, dents and bends easily when worn daily. Heavy settings or intricate designs may lose shape over time, requiring professional reshaping. Additionally, the higher gold content commands a premium price, which can put a dent in your budget if you want larger or custom pieces.

18k vs 14k Gold: Pros and Cons

Two of the most popular standards for fine jewellery are 18k vs 14k gold. Each offers a distinct balance between visual appeal and durability.

What is 18k gold?

18k gold consists of 75 % pure gold and 25 % alloy metals. It retains a deep yellow hue that complements diamonds and gemstones. At Gillian’s Jewellery, we frequently recommend 18k for engagement rings because its colour adds a sense of luxury without sacrificing too much strength.

What is 14k gold?

In contrast, 14k gold contains 58.5 % gold and 41.5 % other metals. This ratio yields a slightly lighter colour but significantly boosts resistance to scratches and bending. Many active individuals choose 14k for wedding bands or bracelets that face daily wear and tear.

Pros of 18k vs 14k gold

When comparing 18k vs 14k gold, the main benefit of 18k is its richer, more vivid colour and higher gold value. Conversely, 14k gold proves more resistant to everyday knocks and is often more affordable. Both alloys suit most designs, but your choice depends on whether you prioritise colour depth or resilience.

Cons of 18k vs 14k gold

If you favour robustness, 18k can still scratch more easily than 14k. On the other hand, the yellow tone of 14k may appear less intense to those who love classic gold. Both alloys contain some alloy metals that could, in rare cases, irritate very sensitive skin.

10k Gold: Pros and Cons

For maximum durability at a friendly price, 10k gold stands out. It holds 41.7 % gold and 58.3 % other metals, making it the hardest karat grade commonly used in jewellery.

Pros of 10k gold

Its lower gold percentage makes 10k the toughest option, ideal for rings worn by active professionals or anyone with a busy lifestyle. It also comes with a more accessible price tag, so you can enjoy genuine gold jewellery without stretching your budget. For example, many clients choose 10k for children’s baptism gifts or daily wear pendants.

Cons of 10k gold

However, the lighter hue can appear paler compared to higher karats. The increased alloy content heightens the chance of skin reactions for those prone to metal sensitivities. Finally, 10k gold holds less resale value, reflecting its smaller gold fraction.

Gold vs White Gold

Beyond yellow shades, many clients explore gold vs white gold. White gold achieves its silvery tone through alloys like palladium or nickel, often finished with a rhodium plating.

Colour and composition

Yellow gold displays warmth derived from copper and silver. White gold, in contrast, offers a cooler, more contemporary look. This modern sheen pairs beautifully with diamonds and coloured stones, making it a popular choice for wedding bands.

Durability and care

White gold often wears slightly better than equivalent yellow karats thanks to its rhodium finish. That plating can fade over time, revealing a faint yellow tint beneath. To maintain its bright appearance, plan for a rhodium top-up every few years.

Price and preference

Generally, gold vs white gold costs are similar at the same karat. Your decision should rest on aesthetic preference and how much maintenance you’re willing to commit. If you love a bright, silvery finish, white gold could be your go-to; if you cherish warmth, stick with yellow gold.

Plated Gold: Pros and Cons

For trend-led styles without the solid-gold price, plated gold—also known as gold vermeil or gold plating—offers a striking option.

What is plated gold?

Plated gold involves a base metal (often sterling silver or brass) coated with a thin layer of real gold. The thickness of that plating, usually measured in microns, determines how long it retains its finish.

Pros of plated gold

First, plated gold jewellery delivers the look of solid gold at a fraction of the cost. It lets you experiment with bold designs or seasonal pieces without a major investment. Our vermeil range uses at least 2.5 microns of 18k plating over sterling silver for longer wear.

Cons of plated gold

Despite thicker layers, plated gold never matches the durability of solid gold. The thin coating can wear away over time, especially on rings or bracelets subject to friction. You must avoid harsh chemicals, perfume and abrasive cleaning. While re-plating can refresh the look, it adds ongoing maintenance.

Choosing the Right Karat: What Karat of Gold Is Best?

Many clients ask, “what karat of gold is best?” The answer depends on three main factors: how often you’ll wear the piece, your budget and your style preferences.

Everyday wear vs special occasions

For daily wear items like wedding bands or work rings, 14k or 10k gold often proves ideal. These karats withstand knocks and retain shape. For statement jewellery or heirloom pieces worn occasionally, 18k or 24k gold shows off that classic yellow glow.

Budget vs long‑term value

If you aim to maximise gold content and future resale value, lean towards 24k or 18k gold. If you have a tighter budget or need a piece you won’t treat gently, choose 10k or 14k. Each step down in karat saves money upfront but contains less pure gold.

Skin sensitivity and style

Also consider any metal allergies. Higher karats contain fewer alloy metals, reducing the risk of reactions. If you have sensitive skin, stick with 18k or 24k gold. For colour variety, choose between traditional yellow or contemporary white gold based on your wardrobe and gemstone pairings.

Our jewellery specialists can show you side‑by‑side samples under natural light to help you visualise the subtle differences in hue and shine.

How Karat Affects Price

When assessing cost, remember price tracks gold content closely. A gram of 24k gold commands a premium over 18k, which in turn costs more than 14k or 10k gold. However, final prices also reflect craftsmanship, design complexity and brand reputation.

At Gillian’s Jewellery, we provide transparent pricing so you see exactly how much you pay for metal purity versus setting intricacy. We also monitor the daily gold price per gram, so small market shifts translate into minor price adjustments on our pieces.

Caring for Your Gold Jewellery

All karats require care to look their best, but methods vary by purity.

Cleaning tips by karat

Use a gentle, pH‑neutral jewellery cleaner or warm soapy water. Soak 24k gold briefly and pat dry with a soft cloth. For 10k or 14k gold, you can brush lightly with a soft toothbrush to lift dirt. Avoid ultrasonic cleaners on plated gold and skip harsh chemicals entirely.

Storage recommendations

Store each item separately in a soft pouch or lined box to prevent scratches. Keep plated gold away from humidity and avoid wearing it in the shower or gym. For white gold, plan a rhodium re‑plating every few years to restore its bright finish. Every six months, bring your favourites to our Melbourne workshop for professional cleaning and inspection.
