Gemstone Guide

What Are Gemstones?

Gemstones are naturally occurring minerals, rocks or organic materials that are valued for their beauty, rarity and durability. When carefully cut and polished, gemstones are transformed into jewellery pieces that have been treasured across cultures for thousands of years.

At Clarindon Jewellers, gemstones are selected not only for visual appeal, but also for their heritage, symbolism and craftsmanship potential, creating jewellery designed to last a lifetime.

Types of Gemstones

Gemstones are commonly divided into two main categories:

Precious Gemstones

Traditionally, the term “precious gemstones” refers to:

  • Diamond

  • Ruby

  • Sapphire

  • Emerald

These gemstones are prized for their rarity, durability and long-standing historical value.

Semi-Precious Gemstones

Semi-precious gemstones include a wide variety of stones, such as:

  • Amethyst

  • Garnet

  • Jade

  • Iolite

  • Jasper

  • Malachite

  • Topaz

Despite the name, many semi-precious gemstones are rare, valuable and highly sought after.

Natural, Organic & Decorative Gemstones

Not all gemstones are crystalline minerals. Some materials used in jewellery include:

  • Organic gemstones such as amber and coral

  • Decorative stones such as Iona marble, Blue John and malachite

These materials are valued for their natural beauty, cultural significance and connection to place.

How Gemstones Are Formed

Gemstones form through a range of geological processes over millions of years, including:

  • Crystallisation from molten rock

  • Metamorphic pressure and heat

  • Sedimentary layering

  • Organic formation (as with amber)

Each gemstone’s formation contributes to its colour, structure and rarity.

Gemstone Colour & Characteristics

A gemstone’s value and appeal are influenced by:

  • Colour – hue, tone and saturation

  • Clarity – natural inclusions or transparency

  • Cut – how the stone is shaped and polished

  • Carat weight – the size and weight of the stone

Some gemstones are admired for brilliance and sparkle, while others are prized for pattern, texture or depth of colour.

Gemstone Meanings & Symbolism

Throughout history, gemstones have carried powerful symbolism. Common associations include:

  • Protection and strength

  • Love and emotional balance

  • Prosperity and abundance

  • Wisdom and clarity

  • Grounding and spiritual connection

Many people choose gemstone jewellery for its personal meaning as much as its appearance.
