Our Inspiration

Fine jewellery has always been associated with life’s most meaningful moments, passed down through generations and treasured for years to come. We wanted to bring that same sense of significance into everyday life.

Essential Diamonds was created from the idea that fine jewellery doesn’t need to wait for a special occasion. We wanted to create pieces that honour the tradition of fine jewellery while feeling modern, effortless, and accessible.

Inspired by classic jewellery silhouettes, each design has been thoughtfully refined with a contemporary perspective, creating pieces that feel familiar yet distinctly BY TONIN.

We focus on creating designs that feel balanced, comfortable, and versatile. Rather than following fleeting trends, we look to enduring forms and reinterpret them through a modern lens, creating jewellery that feels relevant today and meaningful over time.

The Diamond Guide

Every diamond we use is a premium lab-grown diamond, selected for its brightness and clarity. 

Like mined diamonds, lab-grown diamonds are graded using the internationally recognised 4 Cs: Cut, Colour, Clarity and Carat. Knowing how each one is classified makes it easier to compare stones and choose the right fit.

Fine Jewellery Designed in New Zealand

BY TONIN is a New Zealand jewellery brand creating thoughtfully designed fine jewellery for everyday life. Founded by Carlo and Mia Tonin, our collections are designed around the belief that jewellery should feel personal, considered, and effortless to wear.

From diamond necklaces and earrings to bracelets and everyday fine jewellery pieces, each design is created to become part of your personal collection.

A Modern Approach to Fine Jewellery

We believe fine jewellery should not be reserved only for life’s biggest occasions. Our approach is to create pieces that bridge the space between everyday wear and fine jewellery. Designs that feel elevated enough to mark meaningful moments, yet effortless enough to wear every day. Essential Diamonds, our debut Fine Jewellery Collection, introduces a considered edit of diamond jewellery crafted in solid 9k gold or sterling silver with lab-grown diamonds. Each piece reflects our focus on simplicity, versatility, and thoughtful design.

Solid Gold, Sterling Silver & Lab-Grown Diamond Jewellery

Our fine jewellery pieces are crafted using carefully selected precious materials. Solid 9k gold offers the beauty and permanence of genuine gold, while sterling silver provides a refined and versatile foundation for modern jewellery design. Featuring lab-grown diamonds, our collection offers a contemporary approach to diamond jewellery. Lab-grown diamonds are real diamonds with the same chemical, physical, and optical properties as mined diamonds, offering the same brilliance and beauty.
