01
Cut
The most critical factor. Cut determines how brilliantly a diamond reflects light.
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.
02
Colour
Graded D–Z, colour measures the absence of yellow tints in a white diamond.
03
Clarity
Refers to the presence (or absence) of natural inclusions within the stone.
04
Carat
Carat measures a diamond's weight — and is often the starting point for budget planning.
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
Traceable from Mine to Ring

The Kimberley Process

Lab-Grown Option
A Sustainable Alternative
For those seeking an ethically created stone, our lab-grown diamonds offer a compelling choice — identical in every physical property to their mined counterparts, with a lighter environmental footprint.
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.
