My only stop for diamonds

"We found the customer service extremely helpful and transparent, all questions were answered quickly. Prices and quality are great and because they're UK based they're easy to deal with on a regular basis. Overall the best online purchasing experience for diamonds in my opinion"

"Such excellent customer care. I had a very specific need that I couldn't find at their website so I asked them for it. Jack answered me in less than 24 hours offering me the perfect solution and made things very easy for me. Totally recommend this website"
