It’s hard to tell which of their diamonds are simulated (another material) or if any are synthetic. Synthetic (Lab grown) diamonds are still diamonds (i.e. Carbon) and for the most part, they are superior to most natural diamonds because of the lack of defects etc… I wouldn’t be sad about having one of these.
I’ve bought stuff from Carat before but from the actual store rather than online. Considering their jewellery as compared to any other in a similar price range and it is very nice. It’s well made and the stones have an amazing look and sparkle.
If you are after an eye catching ring rather than an actual diamond, I don’t think you will be disappointed.
