    Lab Grown vs Mined

    Same fire. Same hardness. Smaller footprint.

    A lab grown diamond is a real diamond — chemically and optically identical to a mined one. The difference is origin, environmental impact, and how far your budget stretches.

    Crafted by hand

    Made in our Sydney workshop.

    An engagement ring is the only piece of jewellery most people will wear every day for the rest of their lives. That's a long time to wear something — so it has to be made properly. Every Monroe Yorke ring is crafted by hand, by a Master Jeweller, in our Sydney atelier.

    We start with a recycled gold or platinum ingot, hand-shape the band, then a Quality Control Specialist places each diamond by hand under magnification. The centre stone is checked for fit, the prongs are formed and burnished, and the ring is polished to a mirror finish before its final inspection.

    The result is a ring you can wear gardening, swimming, sleeping, and signing important papers — and still feel beautiful in twenty years. That's our definition of an engagement ring done properly.

    “I cannot believe this is lab grown. The fire is unreal. Got the 2ct round in 18ct white gold and it looks twice the size for half the price. The team in Sydney were incredible to deal with.”

    FAQ

    Questions worth asking.

    Yes — they're chemically, physically and optically identical to mined diamonds. They have the same 10/10 hardness, the same brilliance, the same fire. They're tested and certified by the same gemological institutes (IGI, GIA). The only difference is that they're grown above ground in a controlled environment over weeks, instead of formed underground over billions of years.
    Lab grown diamonds skip the multi-billion-year geological process, the extractive mining, and several intermediate steps in the supply chain. The result is a stone of equivalent (or higher) grade at typically 40-60% less than a mined equivalent. You can either buy a much larger stone for the same budget, or pocket the difference and have a beautiful ring at a more accessible price.
    Yes — your Monroe Yorke ring includes complimentary resizing within the first 12 months. Solitaire and halo settings can typically be resized up or down by 2 sizes safely. We recommend ordering a complimentary ring sizer first (free, ships in 2-3 days) so you nail it first time.
    Every ring is hand-finished to order in our Sydney workshop. Standard lead time is 42 days from order confirmation — that includes sourcing the centre diamond, fabricating the setting, setting the stone, and final inspection. If you need it sooner for a specific date, contact us about priority craft options.
    We hope this isn't relevant — but our 14-day return policy applies to engagement rings. Return for a full refund within 14 days, no questions asked. After 14 days, we'll happily help with a custom redesign credit if circumstances change.
    Yes. We have showrooms in Sydney, Melbourne, Brisbane and Perth. Book a complimentary 30-minute consultation and we'll have your design ready to view (or a comparable piece), plus loose diamonds in your shortlisted size and shape so you can see exactly what you're buying. Walk-ins welcome too.
