I had them customize an engagement ring. I was looking for a 3 carat diamond solitaire ring and I went with Katt because they had really good deals and they had so many diamonds to choose from. Very big inventory. I got a 3.24 carat oval ring from them and I had them customize a ring for me. The designer was in-house and the jewelers were all in-house that’s how they were able to give such an amazing price. They did everything in one office and I guess that’s how they cut cost so much. My ring ended up being beautiful, they created a design using a design software, showed me a sketch and then they printed it on their 3d printers. Then after I approved the design it went into production. I got a 3.24 carat oval diamond and a platinum ring with hidden halo all natural for 15k. It was a really good price compared to the jewelry stores I went to and the online retailers. I spent a lot of time researching for the best place to buy an engagement ring and this is it. KATT gave me a beautiful diamond, amazing customized design in platinum for a very good deal.
