Miley Cyrus’ Engagement Ring: The Return of the Cushion Cut Diamond in 2025

The world of luxury jewellery has a new icon, and once again, celebrity engagement rings are shaping global trends. Miley Cyrus’ engagement ring, revealed in 2025, confirms what we predicted earlier this year: big, bold, chunky engagement rings are officially back.

Miley Cyrus became engaged to her longtime partner Max Morando, who proposed with a striking signet-style cushion cut diamond ring by Jacquie Aiche. The centre stone is believed to be a 5-carat cushion cut diamond, set in 14ct yellow gold, with an estimated value of $500,000 USD. A powerful statement ring that blends modern craftsmanship with vintage romance.

The Cushion Cut Diamond Is Back in the Spotlight

The cushion cut diamond is experiencing a major resurgence in 2025. With its soft, rounded corners and brilliant faceting, the cushion cut offers the perfect balance between antique charm and modern luxury.

An elongated cushion cut diamond creates a refined rectangular silhouette while maintaining the fire and sparkle this cut is known for. It is elegant, glamorous and effortlessly timeless.

High-profile celebrities who have chosen cushion cut engagement rings include:

• Taylor Swift
• Zendaya
• Kim Kardashian (her iconic Paris ring)
• Meghan Markle
• Chrissy Teigen
• Priyanka Chopra

This consistent celebrity endorsement has re-established the cushion cut as one of the most desirable diamond shapes for engagement rings.

A Brief History of the Cushion Cut Diamond

The cushion cut is one of the oldest diamond shapes, originally known as the old mine cut. Around 25 years ago, Tiffany & Co. reignited global demand for cushion cut diamonds during the release of The Great Gatsby, supplying many of the film’s most memorable jewels.

For more than a decade, it became one of the most requested diamond shapes worldwide. After a brief slowdown in recent years, demand is once again surging — now expanding into:

• Champagne diamonds
• Chocolate diamonds
• Yellow diamonds
• Antique and repurposed cushion cut diamonds

This reflects growing interest in sustainable luxury and bespoke engagement ring design.

What Makes a Cushion Cut Diamond Different?

Cushion cut diamonds are deeper than many other shapes, with a larger portion of their weight distributed through the girdle and pavilion. This gives them their signature soft, “pillowy” appearance.

Because of this depth, cushion cuts are technically difficult to cut well. Poorly cut stones can display:

• Windowing (transparent areas)
• Dark or blacked-out zones
• Uneven brilliance

A well-cut cushion diamond, however, delivers extraordinary fire, depth and character, making it a standout choice for a custom engagement ring.

Miley Cyrus’ Bezel-Set Engagement Ring

Miley’s diamond is secured in a rub-over bezel setting, where the gold is seamlessly pressed over the edge of the diamond. This setting style is celebrated for both its sleek, contemporary appearance and its exceptional durability.

Bezel settings offer:

• Maximum stone protection
• A clean, architectural aesthetic
• Superior security for everyday wear

At Thelis, bezel-set engagement rings are a signature style for clients seeking modern luxury with practical longevity.

How a Cushion Cut Engagement Ring Is Made

There are three primary methods for crafting a bespoke cushion cut engagement ring:

1. Handmade Bench-Made Rings

Starting from raw stock gauge gold, the ring is entirely formed by hand — rolled, shaped, soldered and refined at the bench. The diamond is then hand-set into the bezel.
This method produces the strongest and most durable engagement rings, free from internal porosity.

2. Hand-Carved Wax Rings

A solid block of wax is carved by hand to perfectly suit the selected diamond. Once approved, the wax is cast into gold, cleaned, polished and hand-set. This allows for exceptional artistic detail.

3. CAD Designed Rings

The ring is digitally designed using Rhino or Matrix software, ensuring perfect proportions. The design is 3D printed, cast in gold and finished by hand, with final stone setting completed by a master jeweller.

Miley’s engagement ring was most likely created using either CAD design or hand-carved wax, both of which allow for precision and customisation at the highest level.

14ct Yellow Gold: What Most Jewellers Won’t Tell You

While 14ct yellow gold is popular for its durability and colour, it is one of the most technically challenging metals to manufacture correctly. If alloyed poorly, it can develop:

• Micro-cracking during production
• A pinkish hue from excess copper
• A pale yellow tone from excess silver

These variations compromise both aesthetic quality and long-term strength.
