Reduced Environmental Footprint
Sourcing diamonds already in circulation avoids the extraction impact associated with newly mined stones. For brands communicating a sustainability position, pre-loved diamonds are a specific, verifiable claim.

A Second Life for Diamonds
When sourcing diamonds, responsibility extends beyond origin. It also includes environmental impact, resource efficiency and respect for the value of materials already in circulation.
At Amanda Jewellery, alongside newly mined stones, we source diamonds from vintage and pre-owned jewellery. By giving these natural diamonds a second life, we help reduce reliance on new extraction while preserving the beauty, rarity and authenticity that make natural diamonds exceptional.
Each stone is carefully assessed and, when required, re-cut or re-polished in-house by our diamond-cutting specialists. This allows us to optimise proportion, appearance and material use while preparing the stone for its new design.
By offering both newly mined and pre-loved diamonds, we give clients greater flexibility while maintaining reliable production capabilities. For brands seeking a more circular sourcing option, pre-loved diamonds provide a responsible alternative without compromising the quality, performance or aesthetics expected of fine jewellery.
"We believe the most sustainable diamond is one that already exists. By sourcing and re-cutting diamonds from pre-owned jewellery, we support a circular economy while delivering the authenticity and excellence expected of fine jewellery."
Why Pre-Loved Diamonds
A Considered Choice for Modern Brands
The Same Diamond, A New Story
Pre-loved stones are natural diamonds — formed over billions of years, assessed to the same grading criteria, and held to the same quality standards as newly mined material. The origin is different. The excellence is not.
In-House Re-Cutting
Where a stone requires re-polishing or re-cutting to meet a design specification, Amanda's lapidary team handles this in-house. There is no third-party handoff, no loss of accountability, and no compromise on the finished result.
Traceable from Purchase
Every pre-loved stone entering Amanda's facility is documented from point of acquisition. Chain-of-custody records are maintained throughout production and available to clients for their own supply chain reporting.
