Before you buy

There is more to a ring than carat.

An engagement ring is a combination of decisions. The stone, proportions, cut, setting, metal, craftsmanship and finishing all influence the final piece.

Understanding those decisions allows you to compare rings intelligently — not simply by the number printed beside the stone.

This guide exists to give you that understanding.

01 / STONES
Know what you're buying

The stone is where the journey begins.

Moissanite, lab-grown diamonds and natural diamonds are different materials with different origins, characteristics and considerations.

01

Moissanite

A gemstone known for exceptional brilliance, strong durability and distinctive optical character. A popular alternative for clients who want substantial visual presence without choosing a diamond.

Brilliant · Durable · Distinctive
02

Lab-Grown Diamond

A diamond created through technology rather than geological formation. It has the same fundamental diamond material and crystal structure as a natural diamond.

Diamond · Lab Created · Authentic
03

Natural Diamond

A diamond formed naturally beneath the earth over geological timescales. Its rarity, origin and individual characteristics contribute to its appeal.

Natural · Rare · Geological
02 / CARAT
Weight is not appearance

What does carat actually mean?

Carat is a measurement of weight. It does not directly tell you how large a stone looks from above.

Carat measures weight.

Two stones with the same carat weight can have different dimensions, proportions and visual presence depending on their shape and cut.

Dimensions influence appearance.

Length, width, depth and the distribution of material all influence how a stone presents on the finger.

Weight What carat measures
Dimensions What you see
Proportions How the stone presents
03 / CUTS
Shape changes everything

Find the silhouette that feels like you.

The cut determines the visual language of the stone. Brilliant cuts emphasise sparkle, while step cuts create a cleaner architectural appearance.

OVAL

Oval

Elegant, elongated and visually flattering.

RAD

Radiant

Modern geometry with brilliant-style faceting.

EMR

Emerald

Clean step cuts with a refined hall-of-mirrors effect.

PEAR

Pear

A teardrop silhouette combining round and marquise influences.

MARQ

Marquise

Long, dramatic proportions that create presence.

CUSH

Cushion

Soft corners with a romantic, substantial appearance.

ROUND

Round

The classic brilliant silhouette designed for sparkle.

PRIN

Princess

Square geometry with a crisp contemporary character.

04 / THE 4Cs
Diamond fundamentals

Learn the four measurements.

The 4Cs give you a framework for evaluating diamonds: Cut, Colour, Clarity and Carat.

C

Cut

How effectively the stone interacts with and returns light.

C

Colour

The degree of colour present in a diamond.

C

Clarity

The presence and characteristics of internal and external features.

C

Carat

The weight of the stone, not simply its apparent size.

05 / SETTINGS
How the stone is held

The setting is part of the design.

The setting affects protection, appearance, profile, sparkle and the overall personality of a ring.

01

Prong

Small metal claws hold the centre stone while exposing more of it to light.

02

Bezel

A surrounding rim of metal secures the stone and creates a clean, modern profile.

03

Halo

Smaller stones surround the centre stone to increase visual presence and create additional sparkle.

04

Hidden Halo

A halo positioned beneath the centre stone creates a subtle detail visible from certain angles.

05

Pavé

Small stones are closely set along the band to create a continuous field of sparkle.

06

Cathedral

Curved or raised shoulders lift the centre stone and create architectural structure beneath it.

06 / METALS
What surrounds the stone

The metal changes the character.

Gold purity, colour, durability and finish all contribute to the final appearance and feel of a ring.

37.5% Gold

9K Gold

A durable gold alloy with a lower gold content and strong everyday practicality.

58.5% Gold

14K Gold

A balance between gold content, durability and everyday wearability.

75% Gold

18K Gold

A richer gold alloy with a higher proportion of pure gold.

Platinum

Platinum

A naturally white precious metal valued for its density and durability.

92.5% Silver

Sterling Silver

A silver alloy commonly used for refined everyday jewellery and accessible custom designs.

07 / PRICE
What actually determines price?

A ring is more than the centre stone.

The final price is influenced by several components, including the stone, metal, design complexity, accent stones and craftsmanship.

01

Centre Stone

Material, size, quality, cut, proportions and origin.

02

Metal

Gold purity, platinum or another chosen material.

03

Design

Complexity, structure, hidden details and custom engineering.

04

Accent Stones

Pavé, side stones, halos, eternity details and additional diamonds.

05

Craftsmanship

The work involved in producing, finishing and quality-checking the completed piece.

06

Service

Consultation, resizing support, warranty and aftercare form part of the complete experience.

08 / CERTIFICATION
Documentation matters

Know what your paperwork means.

Certification and documentation can provide important information about a stone's characteristics.

Read the document.
Understand the stone.

For diamonds, a grading report can document characteristics such as the 4Cs and measurements. Moissanite may come with separate documentation or certificates depending on the supplier and stone.

Documentation should be considered alongside the actual proportions, visual appearance and specifications of the stone.

09 / MISTAKES
Before you decide

The mistakes worth avoiding.

The best purchase is an informed one.

01

Choosing only by carat

Weight alone does not determine how large or beautiful a stone appears.

02

Ignoring proportions

Table, depth and length-to-width ratio can dramatically influence appearance.

03

Comparing only the headline price

Two rings can look similar in a photograph while differing significantly in materials and construction.

04

Forgetting the setting

The setting influences both aesthetics and how the stone is secured.

05

Choosing the wrong metal

Consider colour, purity, durability and how the metal complements the stone.

06

Skipping the details

Warranty, resizing, finishing and aftercare matter long after the purchase.

11 / FAQ
Still wondering?

The questions worth asking.

Is a larger carat always better?

No. Carat measures weight. Appearance is also influenced by dimensions, proportions, shape, cut and setting.

Is lab-grown diamond a real diamond?

Yes. Lab-grown diamonds have the same fundamental diamond material and crystal structure as natural diamonds; their primary distinction is their origin.

Why can two stones of the same carat look different?

Different shapes and proportions distribute their material differently, changing their face-up dimensions and visual presence.

What makes a stone sparkle?

Light performance is influenced by cut quality, faceting, proportions, polish, symmetry and the material itself.

Which metal should I choose?

The right metal depends on your preferred colour, gold purity, durability requirements, budget and the overall design.

Can I create a completely custom ring?

Yes. A custom design can be developed around your preferred stone, metal, setting, proportions and personal details.
