My boyfriend and I had the opportunity to work with D'Angelo and Klein (hereafter, D & K) on a custom engagement ring. I had seen a gorgeous ring in their window after which I wanted to model my own engagement ring. Since my fiancé and I currently live in different states (I live in Philly), he had to manage the process from afar--but we felt confident in D&K's assurance that they could replicate the ring in their window.
How did they do? Overall, OK. The first attempt was not right--there were significant departures in the design from the ring in their window, but to D & K's credit, after trying to do a quick fix, they agreed that the ring needed to be re-done.
The second attempt, though delivered a few days beyond the promised pick-up date, was better, but there are still a few signs of less-than-ideal work. The center diamond is set bit off center and some of the diamonds in the halo surrounding the center diamond are unevenly set.
All-in-all, my experience with D & K was friendly, but in the end, better workmanship was desired.
