A brilliant centre, beautifully framed

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?

Extra sparkle without surrounding the centre diamond
Greater visual width and finger coverage
Pavé, channel, graduating and tapered accents
IGI-certified Lab-Grown diamonds where applicable
Refine the diamond detail

Popular Side-Stone Setting Styles

01

Pavé Side Stones

Small diamonds set closely along the band for refined sparkle.

02

Shared-Prong Accents

More diamond visibility and a delicate diamond-led look.

03

Channel-Set Diamonds

A smooth, streamlined and secure finish.

04

Graduating Side Stones

Diamonds reduce in size away from the centre.

05

Tapered Baguettes

Architectural lines frame the centre stone elegantly.

06

Split-Shank Sides

A divided band adds width and brilliance.

07

Cathedral Side-Stone

Raised arches support the centre diamond.

08

Hidden Halo Side-Stone

Side-view sparkle beneath the centre stone.

Balanced brilliance

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.

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.

More brilliance across the band

Why Choose Lab-Grown Diamonds?

Side-stone designs benefit from consistent quality and greater flexibility across multiple diamonds.

Helpful answers

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.
