This place is fine for resizing and settings, but if you wish for more, the workmanship is unrefined and poorly executed. If you want them to create a setting or perform any metal-smithing beyond the basics, the work can be asymmetric, lumpy, and crude.
I have had several pieces made here. Mounting stones in prefab settings was fine. Casting was ok. Where we ran into problems was custom work where I provided photos and drawings and when the resulting piece ended up looking nothing like the original blueprint. What really bothered me was when I was charged for each revision, and the custom piece ended up costing more than double the original estimate.
