Coloured gemstones have become increasingly popular in engagement and wedding rings in recent years. More and more people are choosing rings that stand apart from the traditional diamond solitaire and reflect their personality, style or personal story.

There are many options, from classic sapphires and rubies to rarer stones such as tanzanite, alexandrite and tourmaline. When choosing the right gemstone, however, colour is only one part of the decision. Durability, maintenance requirements and the way the ring will be worn all influence how well a gemstone is suited to years of everyday use.

In this guide, we explore the most important factors to consider when choosing a coloured gemstone.

Why Choose a Coloured Gemstone?

A coloured gemstone gives a ring a distinctive and personal character. The colour may reflect a favourite shade, birth month, meaningful memory or simply a visual preference that feels right.

Many clients also look for an alternative to the traditional colourless diamond. A coloured gemstone can create a striking appearance without requiring a particularly large stone, and it can give a ring an entirely different mood and personality.

Popular coloured gemstones for engagement and wedding rings include:

• Sapphire
• Ruby
• Emerald
• Morganite
• Aquamarine
• Tanzanite
• Alexandrite
• Tourmaline
• Spinel
• Topaz

Each gemstone has its own character, colour palette and practical qualities.

Gemstone Durability Matters

Engagement and wedding rings are often worn every day for years or even decades. For this reason, it is important to consider not only the appearance of a gemstone, but also how well it withstands regular wear.

Gemstone hardness is measured on the Mohs scale, where diamond ranks at 10. A higher hardness helps protect a stone from scratching, but hardness alone does not determine durability. Cleavage, toughness and the internal structure of the gemstone also influence how well it withstands everyday use.

At Torkkeli Jewellery, we generally recommend gemstones with a hardness of at least 8 on the Mohs scale for rings intended for daily wear.

These include:

• Sapphire (9)
• Ruby (9)
• Spinel (8)
• Alexandrite (8.5)

Many slightly softer gemstones are also popular in rings, but it is important to understand that they may be more susceptible to scratching or damage during active daily wear.

These include:

• Aquamarine (7.5–8)
• Morganite (7.5–8)
• Emerald (7.5–8)
• Tanzanite (6–7)
• Peridot (6.5–7)
• Amethyst (7)

This does not mean that these gemstones cannot be used in rings. Instead, we recommend considering your lifestyle, work and hobbies when making the choice.

Coloured Gemstones Often Require More Care Than Diamonds

Many people are surprised to learn that coloured gemstones can begin to look dull or dirty more quickly than diamonds.

With everyday wear, rings naturally collect skin oils, hand cream, soap residue, cosmetics and other impurities. On coloured stones, these deposits can sometimes be more visible than on a colourless diamond, reducing both the intensity of the colour and the stone’s natural brilliance.

For this reason, jewellery set with coloured gemstones, especially rings, may require slightly more frequent cleaning to keep them looking their best.

Regular cleaning helps restore clarity and allows the natural colour of the gemstone to come through more beautifully.

Sapphire: The Most Popular Coloured Gemstone for Rings

Sapphire is best known for its deep blue colour, but it occurs naturally in many other shades as well.

Its popularity comes from its excellent durability, classic beauty and timeless character. With a hardness of 9 on the Mohs scale, sapphire is one of the best coloured gemstone options for everyday wear.

Sapphire has traditionally been associated with loyalty, wisdom and lasting love.

Ruby: Bold, Elegant and Durable

Ruby belongs to the same corundum family as sapphire and also has a hardness of 9 on the Mohs scale.

Its rich red colour has been associated with love, courage and passion for centuries. Ruby is an excellent choice for someone who wants a vivid and expressive gemstone without compromising significantly on durability.

Morganite: Soft Romantic Colour

Morganite is known for its delicate pink and peach tones.

Its subtle colour palette has made it a popular choice for romantic engagement rings, particularly when paired with rose gold.

Morganite is somewhat softer than sapphire, however, so it benefits from more careful wear and regular maintenance.

Aquamarine: Light and Fresh Blue

Aquamarine is known for its pale blue colour, often reminiscent of clear seawater or a summer sky.

Many clients choose aquamarine for its fresh and airy appearance. Like morganite, aquamarine belongs to the beryl family and is one of the most popular lighter-toned coloured gemstones used in engagement rings.

Emerald: The Classic Green Gemstone

Emerald is one of the world’s most highly valued coloured gemstones.

Its rich green colour has made it desirable for thousands of years. Emeralds often contain natural inclusions, which are part of their distinctive appearance and individual character.

Because emerald can be more delicate than many other gemstones, protective setting and careful wear are particularly important.

Tanzanite: Rare and Fascinating

Tanzanite is known for its blue-violet tones, which can shift depending on the light.

It is a rare gemstone found only in one area of Tanzania. Its distinctive colour makes it an intriguing choice for someone looking for something less conventional.

Because tanzanite is softer than sapphire or ruby, it requires more care in everyday wear.

Which Gemstone Is Right for You?

Every gemstone has its own strengths.

If durability is the main priority, sapphire and ruby are often excellent choices. If you are drawn to a particular colour or want a more individual look, morganite, aquamarine, emerald or tanzanite may be the right option.

The final choice should reflect your personal style, lifestyle and how the ring will be worn.
