this thread is a few years old, but there are a ton of Quest rings in it.
I am no longer the owner of the first ring...another Pricescoper now owns it and had it re-made into a bezel and it's fabulous.
The Quest guys did my e-ring a few years back (it's is on pg 3 of that thread) and it has held up really well. While many have lost stones from their pave rings, I have not lost one yet in almost 5 years!
