    How to choose diamonds

    Use this collection as the starting point for comparing diamond origin, colour, shape, certification and final design suitability.

    01

    Choose the origin

    Natural and lab-grown diamonds differ in rarity, availability, price and long-term value. Start there before comparing grades.

    Natural vs lab-grown
    02

    Balance the 4Cs

    The best stone is rarely just the largest one. Shape, cut, colour and clarity need to work together in the finished piece.

    03

    Design around it

    The setting, metal and proportions can make the same diamond feel minimal, vintage, bold or delicate.
