Louisa – Princess Cut Diamond Solitaire Ring

A princess cut is cut square and left square. No rounded corners, no softening. It's the most architectural of the popular shapes, and on a plain tapered band with nothing else competing, that's the whole point of Louisa. One stone, four claws, a band that gets out of the way.

Seven metals, one design

Louisa is made in 14ct and 18ct white gold, yellow gold and rose gold, and in 950 platinum. 14ct is harder and costs less. 18ct carries more colour, which shows most in yellow and rose. Platinum is the heaviest on the hand, and it's naturally white rather than plated white, so it doesn't fade.

Whichever band colour you choose, the claws holding your centre diamond are white gold or platinum. White metal disappears against a colourless stone, so the diamond looks whiter and larger than it would in yellow claws. On a solitaire, where there's nothing else to look at, that matters more than usual.

The centre diamond is yours to choose

The centre stone isn't included in this price, and that's deliberate. You choose it at the next step. Louisa takes a princess, emerald or radiant cut, all hand-selected against our light-performance standard. Natural stones come GIA certified, lab grown come IGI certified, and every one is graded Excellent or Ideal for cut. Nothing below that gets into a Monroe Yorke ring, because cut is what decides whether a diamond gives the light back or lets it fall through the bottom.

A solitaire hides nothing, so this is a design where the grade of the stone does all the work.

Made to order in our Australian workshop

We don't keep Louisa on a shelf. Each one is made to order and hand-finished by our master jeweller. The band is gently tapered and sits flat against a wedding ring. It arrives with our Lifetime Warranty and free insured shipping anywhere in Australia.

Care & warranty

Everyday wear

Your ring is hand-finished for daily wear. Take it off for the gym, contact sports, gardening, and heavy manual work. Diamonds are the hardest natural material but can chip on impact against another diamond or a metal surface. Chlorine from pools accelerates gold's oxidation over years, rinse the ring after swimming.

Cleaning at home

Weekly: warm water, a drop of mild dish soap, a soft toothbrush, and pat dry. Focus on the underside of the centre diamond and behind the setting, where skin oils collect and dull the light return.

Professional maintenance

Every 12 to 18 months at any of our four showrooms. Included in the lifetime warranty at no cost. We ultrasonic-clean, re-tip any worn prongs, polish the band, and inspect the setting under 10x loupe.

Resize policy

Complimentary resize within 60 days of delivery. After 60 days, resizes are $180 within Australia (we cover return shipping both ways). Turnaround is five to seven business days.

Warranty scope

Lifetime warranty covers workmanship, prong integrity, and metal wear. Does not cover accidental damage, loss, theft, or wear from harsh chemicals. Every warranty claim starts with a free inspection at any of our four showrooms or by mail-in.
