About Us

Oscar & Co exists for a simple reason: brilliant diamonds shouldn’t come at the cost of the earth they’re taken from. Every stone we set is grown, not mined — identical to a natural diamond in every way that matters, chemically, physically, and optically, created with a fraction of the environmental footprint.

Diamonds, done differently

We work exclusively in lab-grown diamonds because we believe brilliance and responsibility shouldn’t be a trade-off. Each stone is independently certified by GIA, IGI, or GCAL, so you can verify exactly what you’re wearing — its cut, colour, clarity, and carat weight — with total confidence.

Crafted, not just assembled

Behind every ring, chain, and setting is a small team of skilled craftspeople working with precision tools and the latest jewellery-making technology. We design each piece to be worn every day for decades, which means it has to be built properly the first time: solid settings, secure claws, and finishes that hold up to real life.

Made in, and for, Australia

We’re based in Australia and built Oscar & Co around Australian customers — from ring sizing to shipping to the way we back every piece we sell. That means free DHL shipping on orders over $150, straightforward returns, and a team that answers when something needs sorting out.

Got questions before you buy? Our FAQ covers certification, sizing, care, shipping, and returns, the size guide and product care pages go deeper on the details, and our Contact page has everything you need to reach us directly.
