About Ethica Diamonds
Ethica Diamonds is a luxury jewellery house established in 2010 with a singular dedication to ethical best practice and sustainability. From our stunning boutique showroom in the Duchy of Cornwall's Nansledan development, Newquay, we create exquisite jewellery featuring laboratory grown diamonds and ethical gemstones.
Founded in 2010 and run by mother and daughter, Ethica Diamonds is a business that has grown completely organically into what it is today: an award-winning, ethical jewellers specialising in fine jewellery set with the upmost sustainable materials and precious stones, namely lab grown diamonds and gemstones, with honest and ethical values at the heart of everything they do.
Instead, I believe that the importance for such a meaningful purchase, especially as it is gifted from the heart, should be focussed on whether it is free from human or environmental harm during its production.
I wanted to show people that there is a kinder, more meaningful way to buy diamond jewellery, without compromising on quality or ethics"
