5 Eternity Ring Design Ideas

An eternity ring is a third ring for your engagement and wedding ring set, that celebrates a milestone in your marriage. Whether you’re looking for an understated ring that complements your existing set, or a statement piece that brings a burst of personality, there are endless ways to make your eternity ring uniquely yours.

Here are 5 design ideas from our Canberra jewellery studio to inspire your eternity ring design.

1. Match Your Eternity Ring to Your Wedding Ring

If you love a symmetrical look, an eternity ring that mirrors your wedding ring allows for a beautifully cohesive ring stack. It’s a great option to celebrate a new milestone or anniversary, while keeping your original engagement and wedding set design. It’s also a thoughtful option if you’re surprising your partner for an occasion - you know it’s a design they already love.

My tip for matching designs: Request a unique marker on the inside of your ring, so you know which is your wedding ring and which is your new eternity ring - an engraving, or a hidden gemstone inside the ring is a beautiful touch.

2. Add Diamonds to a Polished Set

If you have a plain polished band for your engagement and wedding rings, choosing a diamond band for your eternity ring adds a beautiful sparkle to your ring set. To complement your existing set, choose the style of faceting - brilliant cut or step cut - that matches the faceting style of the gemstone in your engagement ring.

My tip for diamond bands: You don’t need to have diamonds all the way around your ring - consider leaving a plain polished portion at the base to allow for easy resizing in future.

3. Include Colour in Your Eternity Ring Design

Diamonds are a classic for engagement, wedding, and eternity ring designs, though coloured gemstones are a beautiful way to incorporate colour, personality and meaning to your set. Small coloured gemstones are available in almost every colour you can imagine. Choose a colour that’s a favourite, that represents a birthstone, or holds a heartfelt meaning for the new moment you’re celebrating, to create an eternity ring design that’s uniquely yours.

My tip for including colour: You don’t need to use all coloured gemstones. Alternating diamonds with colour, or even one single coloured gemstone, can have a wonderful effect in an eternity ring design.

4. Design Custom Shaping for Your Eternity Ring

Most wedding bands are made with straight, parallel edges, which makes your eternity ring a perfect opportunity to explore more sculptural shapes. Even with designs using standard gemstone shapes (like round brilliant cuts), ring profiles can be shaped with elegant sweeping designs.

My tip for shaped designs: Play with how you wear the ring to unlock more options for styling your set day to day. Rings with custom shaping are beautiful to wear on their own, with only your wedding ring, or with both your engagement and wedding ring.

5. Wear Your Eternity Ring on a Different Finger

Your eternity ring doesn’t have to sit beside your engagement and wedding rings. While that’s the traditional option, your ring collection is yours alone - you can design your eternity ring to be a standalone piece for a different finger entirely.

Whether you love your engagement and wedding ring set just as it is, or you’ve fallen in love with a style that doesn’t match them, designing your eternity ring for your right-hand ring finger instead of the left allows for complete freedom to create a freestanding design, from scratch.

My tip for right hand rings: I’ve created right hand eternity rings in every style - from pieces matching the wedding ring, through to large statement coloured gemstone pieces. The possibilities are endless. Don’t let traditional designs limit you.
