While great strides have been made in reducing the historically high emissions produced by mining and manufacturing gemstones and precious metals, the carbon footprint or lab-grown stones made with renewable energy is lower. Recycling precious metals - gold, silver and platinum - also helps to cut emissions, though Anabela has recently gone one step further, pioneering the use of recycled aluminium soda cans in her designs.

Ethical and sustainable practices have always been central to the brand's ethos. Even so, Anabela agrees there is always more to do. Last year the brand set up a digital virtual reality channel so customers can shop virtually, while sales from the new Mermaid's Tale collection go to support and restore coastal ecosystems. ‘Coastal ecosystem, like kelp forests, mangroves and seagrass can sequester up to 20 times more carbon per acre than land forests. One mangrove tree stores approximately one ton of co2, creates critical habitat for marine life and provides sustainable employment for local communities. So, when we launched this ocean-inspired collection we committed to planting 100 mangrove trees in West Papua for every piece sold.

For Anabela, reducing carbon footprint is only part of the story: 'It is one of sustainability’s three pillars. The second is the human ethical issue - how everyone involved in your business is being looked after, ensuring that nobody is being exploited anywhere along your chain of supply. The third pillar, Anabela believes, is the socio-economic impact. 'The pandemic has sadly seen so many brands go under with significant debts, many operating on extensive loans, often to facilitate rents for multiple premium real estates and extensive marketing costs. Yes, a business might be using organic cotton for its products and have a zero plastic packaging policy, but that alone doesn’t make it a sustainable business.’

On whether her industry is doing enough to combat climate change, she says: ‘It’s about looking at how thighs were done in the past and learning how to do them better for the right reasons. Greenwashing won’t help us. ’

Does she think her customers – who include Beyoncé, Rihanna and Taylor Swift – actually care about sustainability? ‘I’d like to think that everyone does. They fall in love with my designs first and the ethical sustainability is a bonus.’
