"I wanted to create a safe place for people who wanted to ask all the questions they needed to, without time pressure or pressure to go over budget. I wanted everyone to feel equally important, regardless of what they could and couldn't spend and I wanted everyone that came to us to understand the truth about the diamond industrys outdated practices and why choosing a more modern forward thinking approach to purchasing fine jewellery was the only genuinely meaningful option." - Elaine Reffel, founder. 

Their jewellery is set with recycled and Fairtrade precious metals and are set with certified lab-grown diamonds and premium independenty certified diamond infused moissanite. They set out back in 2010 with a mission to educate the consumer about the dark truths of diamond mining and provide an ethical and more affordable alternative that did not compromise on durability, composition, beauty and of course, sparkle! 

The Ethica Team have a passion for making customers happy and have remained small and close knit team in order to continue a highly personal and attentive customer service. They have been awarded the Feefo Platinum Trusted Service award for the past three years, following a successful three years of being awarded the Feefo Gold standard. These awards recognise consistence in delivering excellence for customer service, which is hugely important to the business.  


The team at Ethica really understand how daunting to prospect of finding the perfect engagement ring can be, and really aim to help take away the stress and make it an enjoyable experience where you feel informed and supported to make the right choice for you.

Our Boho Supplier Values

Ethica Diamonds

Environmentally Sustainable Work Practises

Sustainability is huge for us here at Ethica Diamonds and there are lots of things we do within our businesses to try and be as eco-friendly as possible. Firstly, we will never used mined diamonds or stones - and instead offer lab-grown diamond and moissanite alternatives. We also take care to ensure we source our lab-grown diamonds from responsible growers, that are either powered by renewable energy or offsetting their carbon emissions. We use recycled and Fairtrade Gold and precious metals wherever possible and our packaging is plastic free, using materials that are FSC certified. We are also partnered with 1% for the planet - The 1% for the Planet certification is given to businesses and individuals that meet our high-bar commitment and donate 1% of annual sales or salary to environmental causes.

Over Deliver

We want every customer to feel like they are our only customer - and our wonderful sales team Olivia and Claire go above and beyond to provide a highly attentive and personal service, as shown in our five star reviews!

Advocate Representation

We don't believe that engagement rings need to cost or look a certain way - every couple is different and so shouldn't their ring be too? Thats why we offer two stone options for two different budgets and offer a huge variety of jewellery designs. We also offer our bespoke ring so you can literally design your dream piece of jewellery, whatever that may be!

"The Ethica Team really know the meaning of customer service. Few people go into the process of buying an engagement ring knowing absolutely everything. it can be daunting and confusing, but the team at Ethica, particularly Olivia, was so helpful in explaining the ins and outs whilst sharing a range of different options that helped me make the right choice. Finding sustainably sources lab-grown diamonds from a UK source is not easy, but Ethica very much make it seem that way"

"I found Ethica Diamonds online after looking into sustainable engagement rings for my partner. I was immediately drawn to their professional yet friendly and ethical approach, and their elegant rings and designs on their website. Despite this I was still beginning to feel overwhelmed by the sheer choice of diamonds and ring settings, but after reading reviews I decided to give them a call. My fears were immediately put at ease, Olivia (and later Claire) were the most knowledgeable, friendly and enthusiastic people to deal with, no question was too stupid and Olivia made a huge effort to help me land on something personal, discuss customisations and generally keep me completely involved in the process whilst also making sure to explain things every step of the way. By the end of what turned out to be a pretty quick process, I knew I had found the perfect ring from the perfect place! Even when I decided I wanted to propose earlier than expected, they worked to turn everything around for me and managed to get the ring with me in time. My partner was absolutely amazed with the ring and she hasn't stopped looking at it! I couldn't recommend Ethica enough." March 2023
