How to choose your metal

Every option is hand-finished in our Australian workshop. The difference comes down to purity, weight and longevity.

  • 950 platinum · 95% pure · Naturally white and hypoallergenic. Never needs plating. The densest metal we work with, so it feels heaviest on the hand. Most enduring choice for daily wear.
  • 18ct gold · 75% pure gold · The traditional standard for fine Australian jewellery. Richer colour, heftier feel. Our recommendation for engagement rings and heirloom pieces.
  • 14ct gold · 58% pure gold · Slightly harder alloy than 18ct, priced a step below. A practical middle ground when durability matters as much as purity.
  • 9ct gold · 37.5% pure gold · The hardest gold in the range and the most affordable. Ideal for everyday chains, pendants and pieces that take heavier knocks.

On colour

  • Yellow gold deepens naturally with age and needs no plating.
  • White gold is rhodium-plated for its bright finish. Re-plate every 2 to 3 years at our workshop.
  • Rose gold deepens slightly with wear. No plating needed.

Which to pick if...

  • Wedding ring worn daily: 950 platinum
  • Engagement ring: 18ct gold, or platinum if you want maximum enduring wear
  • Everyday chain or pendant: 9ct for durability, 18ct for finer finish
  • Sensitive skin: platinum or high-karat yellow gold (avoid rhodium-plated white gold if you react to nickel; some rose gold alloys can react to copper sensitivity)

The Story

Crafted with intention.

A black diamond at the centre. A halo of white around it.

Most engagement rings begin with a colourless centre stone and work outward. The Jetta begins with a black diamond. The choice is uncompromising. A natural black diamond has a depth no other stone can replicate, an opacity that catches light from the surface rather than from inside. Surrounded by a halo of small white accent diamonds, the centre stone reads as a point of darkness against light. There is nothing else like it.

The contrast is the design. White diamonds gather around the black, framing it like a halo of stars around a planet. The yellow gold band lifts both. From across a room, the ring reads as a single bold point. Up close, the halo's geometry becomes visible.

This is the yellow gold version. The warm gold against the black centre stone creates the strongest visual contrast of any metal we make this ring in. White diamonds in the halo, black diamond in the centre, yellow gold holding it all. The colour combination is the most distinctive engagement ring we sell.

Natural black diamond at 1.5ct centre with white accent halo, available in 14ct yellow gold, rose gold, or 18ct yellow gold. The natural option is $5,895 and carries genuine geological age. The lab grown black diamond version (chemically identical, IGI certified) is $4,495 if you want the same look at a lower price.

Every Monroe Yorke ring goes through ten distinct stages over four to eight weeks. Design refinement. Three-dimensional modelling. Casting. Stone sourcing. Cleaning. Polishing. Setting. About eight hours of bench-level finishing. Quality control. And the final approval our master jeweller signs off himself. Made in Australia, ten stages, no shortcuts.

Who this ring is for

You've decided you don't want the usual engagement ring. You've looked at white-diamond solitaires and they all read as the same idea. You want a ring that makes a statement, that conversations start around. Black diamonds aren't traditional. They're not for everyone. That's the point.

If you want the white gold version, see the Jetta Black Diamond in White Gold. If you want platinum (the heavier, more secure metal at this carat weight), see the Jetta Black Diamond in Platinum. For the full black diamond collection, see Black Diamond Rings.
