Engagement Ring Buying Guide

We love being part of all your biggest moments and when it comes to buying an engagement ring it’s all about the little details.

By getting these right, we know that you’ll choose the ring they’ll treasure for a lifetime – because if it means the world to you, it does to us too.

The Design

Main image

Choosing Your Ring Style

Halo Engagement Rings

A halo engagement ring, as the name suggests, has a “halo” of smaller diamonds or gemstones surrounding the centre stone, accentuating its size. This style is often associated with vintage styles, with many halo engagement rings being popular in the art deco and victorian era, although we also have a selection of minimalistic and modern halo designs in our collection. 

Main image

Solitaire Engagement Rings

Solitaire engagement rings are one of the most classic designs for an engagement ring due to their simplicity and timelessness. Originating from the Latin word “solus” meaning ‘alone’ or ‘sole’, solitaire rings feature just one single diamond or gemstone.

Main image

Shoulder Set Engagement Rings

Shoulder set designs feature very small diamonds which are set along the band (also known as the “shoulders” of a ring, hence the name!), often in pavé settings.  Diamond set shoulders add more sparkle and interest to the setting without distracting too much from the centre stone.

Main image

Multi-Stone Engagement Rings

A multi stone ring is one that features more than one main stone. This could be a three-stone (trilogy) engagement ring, a two-stone (toi-et-moi) engagement ring or, less traditionally, a five-stone engagement ring. Having more than one main stone means that these designs lend themselves perfectly to featuring coloured gemstones alongside a diamond, adding colour and more individuality to the ring.

Main image

Trilogy Engagement Rings

Trilogy engagement rings feature three stones and have a sentimental meaning, where each stone represents the past, present and future together as a couple. These designs lend themselves well to incorporating colour into a ring, as well as different shaped diamonds or stone on the sides. 

Main image

Hidden Halo Engagement Rings

Hidden halo engagement rings feature a hidden row of smaller diamonds or gemstones beneath the centre stone, adding extra sparkle and enhancing the overall interest of the ring. This style emerged as a way to give a stunning and unique twist to the traditional solitaire setting. 

Main image

Accented Engagement Rings

Our accented engagement rings feature a central diamond or gemstone which is complemented by other small diamonds or gemstones, adding interest and extra sparkle.  Many of our most popular engagement rings have accents, since they can make the design more unique and personal.

Main image

Vintage Engagement Rings

From floral designs and intricate milgrain details to bold rings with big stones, there are many different characteristics which define vintage style engagement rings. Our collection of vintage engagement rings take inspiration from a few different era’s , with designs which are perfect for lovers of timeless classics, as well as those who have a boho style.

Main image

Modern Engagement Rings

Our modern engagement ring collection features designs which are minimal and clean, as well as designs which have emerged more recently with thin bands and talon claws. 

Main image

Dainty Engagement Rings

Our dainty ring collection are the ring styles with slimmer bands or other details which are considered more delicate and feminine.

The Stone

Choosing your stone type

The shape of the stone is fundamental to how it looks, and every shape has a different cut, sparkle and meaning behind it.  We can source lab diamonds and our signature moissanite, Ethica Diamond in any shape, in addition to the ten most classic shapes.

Want to add colour?

We searched the globe for lab grown gemstones which match or exceed the quality of natural gemstones, with the same crystal and atomic structure, so that we can offer traceable coloured gemstones that are just as beautiful as those from mined origins.

The Metal


18k Yellow Gold

18k Yellow Gold is an alloy of gold which is durable and strong, with a warmth and lustre loved by many. We use 18k in our jewellery for the beautiful warm tones, whilst being strong - not brittle - and safe to set with precious gems.


18k White Gold

18k white gold is an alloy of gold with a silver colour. 18k white gold isn’t intrinsically silver; it is plated with rhodium to make it silver or “white”. The colour of white gold is very slightly warmer than that of platinum, but they are generally indistinguishable by most people.


18k Rose Gold

18k rose gold is a red/ coppery alloy of gold which is a different colour due to a higher ratio of copper in the alloy. It is a more unusual option for engagement rings since it isn’t the typical, classic choice, but this uniqueness is why many opt for it.



Platinum is a silver coloured metal which is extremely durable and strong, making it the optimum choice for engagement rings set with precious stones. It is silver all the way through, making it the preferred option by many over 18k white gold.
