Lab-Grown Diamond Side-Stone Engagement Rings
Discover Lab-Grown diamond side-stone engagement rings designed to enhance the centre diamond with refined sparkle along the band. Side stones create extra brilliance and finger coverage while allowing the main diamond to remain the hero.
Pear Jewels Australia offers side-stone rings in oval, round, pear, emerald, marquise and cushion shapes, with pavé, channel-set, tapered and graduating accent designs in white, yellow and rose gold.
Why Choose a Side-Stone Ring?
Best Diamond Shapes for Side-Stone Engagement Rings
Popular Side-Stone Setting Styles
Pavé Side Stones
Small diamonds set closely along the band for refined sparkle.
Shared-Prong Accents
More diamond visibility and a delicate diamond-led look.
Channel-Set Diamonds
A smooth, streamlined and secure finish.
Graduating Side Stones
Diamonds reduce in size away from the centre.
Tapered Baguettes
Architectural lines frame the centre stone elegantly.
Split-Shank Sides
A divided band adds width and brilliance.
Cathedral Side-Stone
Raised arches support the centre diamond.
Hidden Halo Side-Stone
Side-view sparkle beneath the centre stone.
Why Side-Stone Rings Stand Out
Enhanced Brilliance
Accent diamonds add sparkle across the shoulders.
Centre Diamond Emphasis
The side stones frame rather than surround the centre.
Greater Finger Coverage
Diamond-set shoulders create a wider look.
Highly Customisable
Choose accent size, band width and setting method.
Wedding-Band Versatility
Many profiles pair well with straight or fitted bands.
Classic With More Detail
More sparkle than a solitaire without a full halo.

| Feature | Side-Stone | Solitaire | Three Stone |
|---|---|---|---|
| Visual focus | Centre with accents along the band | One centre diamond | Centre with two larger side stones |

| Best for | Extra sparkle with centre focus | Minimal elegance | Meaning and width |
How to Choose the Perfect Side-Stone Ring
Prioritise the Centre Diamond
Review cut, proportions, polish, symmetry and certification.
Match the Side-Stone Proportions
Accents should enhance the centre without crowding it.
Choose the Accent Style
Pavé feels delicate, channels feel smooth and baguettes feel structured.
Plan the Wedding Band
Check whether a straight or fitted band will sit best.
Why Choose Lab-Grown Diamonds?
Side-stone designs benefit from consistent quality and greater flexibility across multiple diamonds.
Side-Stone Engagement Ring Guides
Side-Stone Engagement Ring FAQs
What is a side-stone engagement ring?
A main centre diamond with smaller accent diamonds along the band or shoulders.
How is it different from a three-stone ring?
Side-stone rings usually use several smaller accents; three-stone rings use two larger side stones.
Do side stones make the ring look larger?
They increase sparkle and finger coverage, making the complete ring feel more substantial.
Can side-stone rings include a hidden halo?
Yes. A hidden halo can add side-view sparkle beneath the centre diamond.
Can I customise the centre and side stones?
Yes. Centre shape, carat weight, accent style, band and metal may be customised.
