Buying Guide

The four decisions that matter

August 2026

Diamond buying has been made deliberately complicated. It is actually four decisions.

1. Shape

Trust first instinct. Ovals look larger for their weight and flatter the finger; rounds return the most light; emeralds trade sparkle for glassy elegance; pears point. There is no wrong answer, only hers.

2. Carat

Carat is weight, not size — but the two travel together. The honest advice: buy the carat that suits the hand, not the ledger. A 1.00ct oval on a slim band reads beautifully; chasing a number rarely does.

3. Quality

Colour, clarity and cut collapse into one question: does the stone face up white, clean and alive? Our three presets answer it at three budgets. Essential is flawless at arm's length; Signature is flawless at conversation distance and our recommendation; Premier is for perfection under the loupe.

4. Metal

18k yellow is the classic; white is the modernist; rose is the romantic; platinum is the heirloom, a touch heavier and a touch cooler in colour. All four are hallmarked at the London Assay Office.

Four decisions, five minutes. Every product page walks you through them, and a human is a message away when you want one.
