Understanding Precious Metals



Understanding Precious Metals

The metal you choose is just as important as the design itself. It affects not only the look of your jewellery, but how it wears, feels, and lasts over time.

At Mandi & Co we guide you through each option — ensuring your piece is as practical as it is beautiful.


Gold — Classic, Versatile, and Endlessly Adaptable

Gold has been treasured for thousands of years for its warmth, richness, and timeless appeal.

In its pure form (24ct), gold is soft, which is why it’s blended with other metals to create strength and durability — while also influencing its colour.

Gold Purity

  • 18ct Gold — A premium choice, offering a beautiful balance of richness and strength

  • 14ct Gold — Slightly lighter in colour, with added durability for everyday wear

  • 9ct Gold — A practical and more affordable option, ideal for frequent wear

Gold Colours

  • Yellow Gold — Warm and traditional, with a classic, enduring feel

  • Rose Gold — Soft and romantic, with a subtle blush tone

  • White Gold — Crisp and modern, finished with rhodium for a bright white appearance

Every alloy is carefully selected to ensure both true colour and long-term wearability.


Silver — Effortless and Elegant

Silver offers a clean, luminous finish that suits both classic and contemporary designs.

  • Sterling Silver (925) — The most commonly used, combining strength with a bright, polished look

  • Fine Silver (999) — Higher purity, softer, and typically used for more delicate pieces

Silver is loved for its versatility and accessibility, making it perfect for everyday jewellery.


Platinum — Naturally Refined

Platinum is one of the most durable and prestigious metals used in jewellery.

Naturally white and hypoallergenic, it doesn’t require plating and will not tarnish. Its weight gives it a luxurious feel, often chosen for engagement rings and pieces designed to last a lifetime.

Over time, platinum develops a soft, satin-like finish — a natural patina that reflects its wear without compromising strength.


Palladium — Modern and Lightweight

Palladium belongs to the same family as platinum but offers a lighter feel.

It shares many of platinum’s benefits — strength, durability, and a naturally white tone — making it a refined choice for those wanting something understated and contemporary.


Finishing Metals & Modern Alternatives

  • Rhodium — A rare, highly reflective metal used to plate white gold and silver, enhancing brightness and resistance to tarnish

  • Titanium — Exceptionally strong yet lightweight, ideal for modern, minimal designs and sensitive skin


Sensitivities & Wearability

Not all metals are created equal when it comes to skin sensitivity.

Some alloys may contain elements like nickel, which can cause irritation for some people. At Mandi & Co we are mindful in our material selection and can guide you toward options that are better suited to sensitive skin, such as platinum, palladium, or carefully selected alloys.


How Metals Wear Over Time

Each metal evolves differently with wear:

  • Gold — Durable, though lower carat alloys may soften in colour over time

  • Silver — Can naturally tarnish, but is easily cleaned and restored

  • Platinum — Develops a soft patina, maintaining its integrity and strength

These changes are a natural part of fine jewellery — adding character rather than detracting from it.


Caring for Your Jewellery

With proper care, your jewellery can last a lifetime and beyond.

Simple habits such as storing pieces separately, avoiding harsh chemicals, and regular cleaning will help maintain their beauty. We also offer professional cleaning and maintenance to keep your pieces looking their best.


At Mandi & Co we believe the right metal should feel as good as it looks — considered, intentional, and made to last.
