Mazzucchelli’s · Since 1903

Half a carat to one carat of diamonds

This range is one of the most loved for a reason. It brings together our engagement rings from Promise, Halo, Royale and Vera Wang LOVE, as well as Mazzucchelli's own designs, alongside diamond studs, wedding rings and eternity rings.

Choosing the right size

Carat is a measure of weight, not size, so two diamonds of the same carat weight can look different depending on their cut and shape. Our guide to the five Cs explains how carat, cut, colour, clarity and certification work together.

Book a time with our diamond experts to talk through your options, or design your own ring from scratch.

More than engagement rings

You will also find dress rings, drop earrings and diamond pendants in this range, each a lasting way to mark a moment that matters.
