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 centre diamond, framed by a halo of white, in white gold

Most engagement rings begin with a colourless centre stone and work outward. The Jetta begins with a black diamond. A natural black diamond has a depth no other stone can replicate, an opacity that catches light from the surface rather than from inside. The white gold band and halo of small white diamonds around it create the contrast that makes this ring read.

White gold is the cleanest metal to set a black diamond against. The metal disappears against the colour of the centre stone, making the diamond read as a single distinct point. The halo of small white diamonds completes the contrast.

Natural black diamond centre, white diamond halo, in 14ct or 18ct white gold (and yellow or rose gold as variants). The natural diamond option is $5,895. The lab grown black diamond version (chemically identical, IGI certified) is $4,495.

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 want a black diamond centre and you want the cleanest possible setting around it. White gold disappears against the centre stone, making the diamond do all the visual work. The Jetta in white gold is the most considered version of this design.

If you want the warm yellow gold backdrop instead, see the Jetta in Yellow Gold. If you want platinum (the heavier metal), see the Jetta in Platinum.
