In the world of engagement jewellery, few choices are as iconic—or as enduring—as the round engagement ring. Loved for its unmatched brilliance, perfect symmetry, and timeless charm, the round cut diamond remains the most popular shape worldwide. When set with man made diamonds, these rings evolve beyond beauty into a symbol of modern values: ethical sourcing, sustainability, and forward-thinking elegance.

Across New Zealand and globally, discerning couples are choosing round engagement rings with man made diamonds as the ultimate blend of tradition and innovation. With breathtaking sparkle and a conflict-free origin, these rings honour both love and the planet.

Why Round Cut Diamonds Remain the #1 Choice

The round brilliant cut is a 58-facet masterpiece, engineered for maximum fire and light return. First perfected in the early 20th century, this shape continues to lead all others due to its universal appeal and dazzling symmetry.

Advantages of round engagement rings:

• Unmatched brilliance due to ideal facet alignment.

• Versatile in design, from solitaires to halos and vintage styles.

• Timeless appeal that transcends fashion trends.

• Perfect for highlighting man made diamonds’ clarity and sparkle.

Whether in a minimalist solitaire or an elaborate vintage setting, the round cut showcases diamonds at their most luminous.

Man Made Diamonds: The Ethical Alternative to Mined Stones

Also known as lab grown diamonds, man made diamonds are chemically, physically, and optically identical to natural diamonds. They are created using high-pressure, high-temperature (HPHT) or chemical vapour deposition (CVD) methods that replicate the Earth’s natural diamond-forming process—just in a matter of weeks instead of millions of years.

Why choose man made diamonds for your engagement ring:

• 100% conflict-free, with fully traceable origins.

• Eco-friendly, using far fewer natural resources and causing no mining damage.

• Greater value, allowing for larger or higher-grade diamonds within your budget.

• Certified and graded, just like mined diamonds, by trusted institutions like IGI and GIA.

With man made round diamonds, you’re not compromising on beauty or brilliance—you’re elevating your values.
