Rihanna's Diamond Comeback at Jay-Z's Yankee Stadium Finale

Rihanna made a rare return to the stage this week, joining Jay-Z for a surprise performance of "Run This Town" at the emotional finale of his three-night Yankee Stadium residency on 12–13 July, before delivering a solo rendition of "Bitch Better Have My Money." She arrived dressed in layered diamond chains and jewels from Jacob & Co, Kwiat Diamonds and other high jewellery houses — a maximalist, stacked-necklace moment that instantly reignited interest in layered diamond chains for anyone dressing for a big night out. The performance, and the jewellery, dominated entertainment headlines all week.

The layered-chain look is easy to recreate without needing a vault of archival diamonds. A lab-grown diamond pendant on a fine chain, doubled up or stacked with a plain gold layer, gives you that same "thrown on but expensive" energy Rihanna is known for.

✨ Love this style? Our Round Lab-Grown Diamond Cross Pendant layers beautifully with a plain chain for that stacked-necklace effect — or tell us exactly what you love and start a custom design.

Stephanie Gottlieb's New Lab-Grown Lines Signal a Bigger Shift

Fine jewellery designer Stephanie Gottlieb launched two new lab-grown diamond collections this week — Lola, under her SG Fine label, and the more accessible Casual Carats, with pieces ranging from around $675 to $7,750 — a notable move from a designer previously associated almost exclusively with natural stones, as reported by JCK. It's a strong signal that lab-grown diamonds have well and truly crossed over from budget-conscious alternative to legitimate luxury choice, backed by designers who once stayed firmly in the natural-diamond camp.

This is exactly the territory Diamondrensu has built its name on. Every lab-grown diamond piece we make is chemically, physically and optically identical to a natural diamond, at a fraction of the price — meaning you can go bigger, bolder or simply save, without compromising on brilliance.

✨ Inspired by this piece? See our Lab-Grown Diamond Stud Earrings with Halo, or design your own — share a photo, a description, or just a feeling, and our jewellers will bring it to life.

The Toi et Moi Ring Every Newly Engaged Celebrity Is Wearing

If 2026 has a defining engagement ring shape, it's the toi et moi — two stones set side by side, symbolising two individuals united as one. It's the ring style behind some of the year's biggest proposals, from Megan Fox and Machine Gun Kelly's interlocking two-ring toi et moi set to Jane Seymour's vintage floral double-cluster design, and it continues to be the most-searched engagement ring style of 2026 according to bridal jewellery trend reporting. Elongated cushion cuts are having their own moment alongside it, edging out the oval as the shape to watch this year.

Toi et moi rings are inherently personal — no two are meant to look the same, which makes them a natural fit for custom design. Whether you want two matching diamonds, a diamond paired with a coloured stone, or two different cuts entirely, the format is built for storytelling.

Why Custom Jewellery Is the New Celebrity Jewellery

Every piece above has one thing in common: none of it was bought off a shelf. Celebrity stylists work with jewellers directly to commission pieces that fit the moment, the outfit and the story being told — and that's exactly the service Diamondrensu brings to Australia. Fill out our custom design brief with a photo, a sketch, or simply a description of what you're picturing, and a design specialist will respond within 1–2 working days with a personalised quote. From there, you'll receive a CAD (Computer-Aided Design) rendering to review and adjust before anything is made, so what lands on your finger, ears or neckline is exactly what you approved. Every piece is crafted to order in lab-grown diamonds or moissanite, giving you the brilliance of fine jewellery without the natural-diamond price tag or sourcing concerns. Bespoke jewellery in Australia doesn't need to mean waiting months or paying a premium for a name — it just means working with people who care about getting the details right.
