RING BUYING GUIDE
WHO IS IT FOR?
First, decide who the ring is for - whether it's a proposal, a milestone gift, or a treat for yourself, the purpose shapes the perfect choice.
1
SET A BUDGET
To find the perfect ring, lead with love, then set your budget.
2
THINK ABOUT THEIR STYLE
Timeless & classic, minimalist & modern - or somewhere in between?
3
CHOOSING A METAL
Each metal tells a different story. Choose the one that suits not only their style, but their lifestyle too.
5
CHOOSE YOUR SHAPE
The stone's shape defines the ring's look. Whether you go classic, modern or something unique, it sets the tone for the design.
CUT
The most important of the 4Cs, cut determines how light reflects through the diamond.
Tip: It's all about sparkle; cut affects brilliance, not just shape.
COLOUR
Diamonds range from colourless to tinted.
Tip: Opt for near-colourless (G-H) for a bright look without the premium.
CLARITY
Clarity reflects how free a diamond is from natural marks.
Tip: VS1-VS2 offers a clean look without overpaying.
CARAT
Carat measures weight, not just size.
Tip: Choose clever settings like halos or slim bands to maximise visual impact.
