From Bond's Gemologists
Understanding Your Diamond
Every diamond has its own story. Our in-house gemologists have put together these detailed guides so that, whether you're starting from scratch or refining your knowledge, you can approach your purchase with real clarity. No jargon — just honest, expert advice from Bond Jewellery & Diamonds.
The Foundation
The 4Cs of Diamond Quality
Four characteristics define every diamond's appearance, rarity and value. Understanding Cut, Colour, Clarity and Carat Weight allows you to make an informed choice — and get the very best diamond for your budget.
Budget & Pricing
How Much Does a Diamond Cost?
Diamond pricing isn't arbitrary — it's a precise reflection of the stone's individual characteristics. A slight improvement in cut grade or a step up in clarity can meaningfully change the price, and knowing why helps you allocate your budget smartly.
Our cost guide breaks down exactly how each of the 4Cs affects price, and where you can make considered trade-offs without compromising on beauty.
Find Your Shape
Diamond Shapes
Shape is often the first decision — and a deeply personal one. From the timeless brilliance of the round to the architectural elegance of the emerald cut, each shape has its own personality. Explore them all and find the one that speaks to you.

Lab-Grown Diamonds
Are Lab Diamonds Right for You?
Created in controlled laboratory conditions that replicate the heat and pressure of the earth's mantle, lab-grown diamonds are physically, chemically and optically identical to mined diamonds — and typically available at a significantly more accessible price point.
Our guide walks you through everything you need to know: how they're made, how they compare to natural diamonds, and how to decide which is the right choice for your ring.
Our Commitment
Diamonds You Can Feel Good About
Ethical sourcing isn't an afterthought at Bond Jewellery & Diamonds — it's central to everything we do. We work exclusively with suppliers who meet the highest standards of transparency and responsibility.
Ethical Sourcing
Traceable from Mine to Ring
We partner only with the most reputable diamond suppliers in the world — those who share our belief that transparency and accountability should never be compromised.
The Kimberley Process

Lab-Grown Option
A Sustainable Alternative
For those seeking an ethically created stone, our lab grown diamonds are identical in every way to their mined counterparts, with a sustainable message at heart.
Beyond White
Coloured Gemstones
A diamond isn't the only way to make a statement. Coloured gemstones bring vivid personality to an engagement ring — from the deep blue of sapphire to the lush green of emerald. Explore our guides to the world's most beloved precious stones.
Sapphire
The classic choice for those seeking colour. Sapphires range from cornflower blue to deep navy — and beyond.
Emerald
Rich, verdant and full of character. Emeralds have adorned royalty for centuries — and are as striking today as ever.
Ruby
Bold, passionate and rare. A ruby centre stone makes an unforgettable statement of love.
