One Of A Kind Engagement Rings

Beyond Tradition: The Tri- Cut Diamond Rings 

After 24 years of crafting jewellery that carries meaning, there comes a point when design transcends adornment. A piece is no longer just beautiful; it reflects individuality and legacy.

That moment has arrived with the new Tri-Cut Diamond Rings, a collection of bespoke diamonds designed to redefine what a modern engagement ring or heirloom piece can be.

A New Chapter in Diamond Design 

Traditional diamond cuts follow established categories such as round, oval, emerald, cushion, and pear, each shaped by long-standing faceting rules.

The Custom Tri-Cut™ Diamond breaks from convention. It introduces a proprietary cut with a faceting structure that optimises brilliance and proportion.

Certified as a Custom Tri-Cut™, this IGI-certified diamond is recognised as a distinct cut, not a variation of an existing form. It represents a fresh direction in contemporary diamond design, where originality meets craftsmanship.

The Tri-Cut Diamond Ring

The Original Tri-Cut Diamond Ring brings this innovation to life. It is a lab-grown engagement ring designed for those seeking something unique.

It was conceived to be personal, meaningful, and elegant. The ring interacts with light in subtle ways, capturing attention naturally.

Years of research into gemstones, form, and light led to the creation of the Custom Tri-Cut Lab Diamond, an IGI-certified lab-grown diamond exclusive to UbyKate.

From the soft curves of the signature ‘U’ Scoops to the high-polish finish, every detail is considered. The result is a refined, modern, and personal engagement ring.

Designed to be worn alone or paired with a contour band, it allows a layered, customisable expression. This makes it ideal for a unique engagement ring in Australia or a future heirloom piece.

The Tri-Cut Diamond Duet Ring

For those drawn to contrast, the Tri-Cut Diamond Duet Ring offers an alternative to traditional diamond rings.

Featuring both 2ct and 4ct Custom Tri-Cut Diamonds, this ring reimagines symmetry and scale, creating a sculptural and individual design.

Crafted from lab-grown diamonds with precision faceting, the Duet Ring enhances brilliance and light play from every angle.

It is more than an engagement ring. It is a piece that marks milestones, celebrates personal style, and is designed to become a modern heirloom.

More Than a Ring

These are not just engagement rings. They are jewellery pieces created for those who value meaning over convention.

Whether chosen as an engagement ring, a celebration piece, or a personal investment in design, each ring becomes part of the wearer’s story.

They are made to endure, not only in material but in relevance.
