I just about fell out my chair when a really old buddy dropped by with the piece. It's large - about one inch by 3/4 inch... but it's not just the size.

The combination of exact picking, and perfect setting results in a seamless wall of diamonds. There's not a gap between any of the diamonds. Take a microscope - I dare you:)

I took a loupe. The stones are set in such a manner it's hard to envision how this level of perfection was done.

Also the stones - the vast majority of the baguette diamonds are tapered baguettes. Varying degrees of taper by the way. In between are a few that look like straight baguettes.

Anyway, all these baguettes are totally colorless and VS1+. Can't find a speck of imperfection. I'm estimating about 4cts total, but I'm being super conservative - could easily be more than 5cts.

Right below the Marquise are a ring of round diamonds. Four larger (about 0.05ct) at the corners are Round Brilliant. Completing that ring below the center are 12 tiny Single Cut diamonds.

The center diamond is a stunning Marquise. It's totally colorless - and beautifully cut. The fact that it's kind of imperfect... based on GIA grading. Sure, but in person, the imperfections that caused GIA to grade the stone I1 are not visible. Nor do they impact the brilliance of the diamond in any appreciable manner.

The rest of the ring is simple making it easy to adjust in terms of size. 1.7mm shank at the palm.

Speaking to out bench guys - they immediately remember the sort of ring - because they came into the business back in the 70's, like me. When rings like this were popular.

But trying to make one today?
Really next to impossible. And the ring is in PERFECT condition. Amazing piece.
