Here’s a diamond that, on paper, looks like the perfect deal because its 4 Cs say that it’s beautiful and brilliant. In reality, however, the diamond is extremely cloudy and dull, virtually without brilliance or sparkle. This is why you should never, ever purchase a diamond unless you know who you’re dealing with. Mervis has the screening processes, the quality and a 100-year reputation to back up every one of its diamonds.

Verdict: Zed Mervis would reject this diamond!
