Brisbane Jewellers Launch Lab-Grown Diamond Brand LOHR for Accessible Luxury

Adam Graham and Paul Mellers have spent years making fine jewellery in Brisbane under their AG Designer Jeweller label. On March 11, they added a second name to their work: LOHR, a fine-jewellery brand built entirely around lab-grown diamonds, now available online and through a Brisbane showroom.

The debut collection opens with three signature rings that reveal how seriously the founders take proportion and cut. The Vestry is a pear-shaped solitaire, a silhouette that rewards a confident stone and an equally confident setting. The Perry takes an east-west orientation with an emerald cut, a choice that flattens the stone across the finger rather than pointing it toward the knuckle, changing how the facets read in natural light. The Hudson pairs a round brilliant with tapered baguette accents, a classic combination that lives or dies by the quality of the side stones and how precisely they're fitted to the shank.

Graham described the brand's purpose in terms of value and access. "We created LOHR for women who want to invest in jewellery that's beautiful and meaningful, and are seeking exceptional quality without the traditional price tag of mined diamonds," he said. "There was a clear gap in the market for pieces that feel luxurious yet attainable, and lab-grown diamonds let us deliver exactly that."

Mellers, for his part, pushed back gently on the idea that origin alone should drive a purchase decision. "We approached LOHR as jewellers first, focusing on quality, design, and the diamonds themselves," he said. "A certificate can describe a stone, but it's the way a piece is made, how it feels on the wearer and how it catches the light that makes jewellery truly beautiful to wear." That framing matters, because the lab-grown diamond market has sometimes reduced itself to an argument about ethics and price rather than craft.

Lab-grown diamonds share the same chemical composition and physical durability as mined stones and typically cost significantly less, a differential that has accelerated consumer interest globally. What LOHR has not yet published, at least not in the materials available at launch, are the specifics that would let a buyer fully assess the value proposition: the karat of the gold or platinum used in the mountings, the certification body grading the stones (IGI and GIA both issue lab-grown diamond reports with different grading scales and reputations), the manufacturing origin of the pieces, and the actual price points for the Vestry, Perry, and Hudson rings. These details matter. A lab-grown diamond in an uncertified mounting tells a different story than one graded by IGI and set in recycled 18-karat gold, and the sustainability claims embedded in LOHR's positioning will only hold up if the supply chain behind them does too.

The brand has not yet announced distribution beyond the Brisbane showroom and its online store, and no lookbook pricing or appointment policy was available at the time of writing. For buyers weighing LOHR against established lab-grown diamond brands with longer track records and published grading documentation, those are the questions worth asking before committing to a ring.
