When choosing a centre stone, there’s no single right answer. Some are drawn to the
brilliance and tradition of diamonds. Others prefer the richness and individuality of
coloured gemstones. Whether you choose natural or lab-grown, colourless or bold,
your stone should feel personal — something that reflects your story.
This guide breaks down the differences so you can make a choice that feels just right.

Natural and Lab-Grown
Diamonds are known for their strength, clarity, and unmatched sparkle. Both
natural and lab-grown diamonds have the same chemical and physical
structure, meaning they are equally durable and beautiful. The difference lies in
their origin.
- Natural diamonds are formed beneath the earth’s surface over millions of
years. Their rarity and natural history make them a traditional and
meaningful choice. - Lab-grown diamonds are created in advanced facilities that replicate the
same conditions found in nature. They offer the same brilliance and
longevity, often at a more accessible price point.
Every diamond we offer — whether natural or lab-grown — is carefully selected
for its beauty, proportions, and quality.
Gemstones
Colour, character, and meaning
Gemstones offer a different kind of beauty, defined by colour, uniqueness, and
emotion. They have natural variation, character, and often a strong sense of
symbolism.
Popular options include:
- Sapphires in deep blues, soft pastels, or striking Australian parti tones
- Rubies with bold, rich reds that symbolise passion and strength
- Emeralds known for their lush green tones and timeless appeal
Each gemstone brings something distinctive. They are often chosen for their
personality, connection to a story, or simply because the colour speaks to you.


How to decide
- Durability: Diamonds are the hardest gemstone and ideal for everyday wear. Sapphires and rubies are also excellent choices for long-term durability. Some gems, like emeralds, are softer and benefit from extra care.
- Style: Diamonds suit almost any setting and offer maximum brilliance. Gemstones bring warmth, individuality, and a touch of artistry to a design.
- Budget: Lab-grown diamonds and many gemstones allow greater flexibility in size and quality at a more accessible price.
- Meaning: There is no single best option. Choose the stone that aligns with your values, your style, or the message you want your piece to carry
