Rectangle Engagement Rings Showcasing the Emerald Cut

Our emerald cut engagement rings blend vintage glamour with modern individuality. Defined by their clean, geometric lines and long, step-cut facets, the stones are cut in such a way as to create a hall of mirrors effect - a distinctive and lively play of light and shadow.

Each ring is consciously crafted from recycled precious metals and available in a variety of bands, including silver, platinum, gold vermeil, 9k gold, and 18k gold. Choose from ethically sourced, conflict-free mined diamonds handpicked for their beauty, or lab-grown diamonds that are chemically and optically identical and match mined diamonds in brilliance and beauty. For those seeking a unique twist, the collection also features designs with sapphires as centre stones.

Explore our emerald cut engagement rings and find the piece that reflects your style and your promise.

RING SIZES & RINGS SIZERS

WHAT IS YOUR RING SIZE?

‘Ring size’ is a measurement that refers to the inside circumference of a ring. It’s important to know your correct ring size before buying a ring, otherwise it won’t fit properly.

Different countries use different standardised systems for denoting ring size.

On the right, there’s a chart with the 3 most common ring size systems used in UK, USA and internationally. For Australian sizes simply refer to the UK sizes, which are the same.

WHY USE A RING SIZER?

Ring size is one of those things we think we’ll always remember… but never actually do!

It is very important to find out the correct ring size whether the ring is for you or another person. This measurement enables us to provide you with a perfectly fitting ring. A ring that is so small you cannot get it on – or so big it falls off – can really ruin a big moment!

Get Your Free Ring Sizer — The First Step to the Perfect Fit

HERE'S A STEP BY STEP GUIDE TO MEASURING YOUR RING SIZE AT HOME.

Watch the video below for our step-by-step guide to using your ring sizer. Just push one end through to make a loop, slip it onto your finger, adjust until it feels snug, and note your size.


OUR RING SIZER APP

Our free Ring Sizer App is accurate and easy to use!

Find out a ring size in UK, EU or USA measurements. All sizes F – Z included, from smallest to largest finger.

Simply place your loved one’s existing ring on your phone screen, then adjust the circle until it fits the inside of the ring exactly.

This app helps you keep an engagement ring or a special gift a surprise and saves you a trip to the jewellers.
