I think it would look great -- I love 60/60 stones.

I like 60/60's with a good idealscope image.

Definitely worth a look.

What is special about 60/60 diamonds?

What is special about 60/60 diamonds?

https://www.pricescope.com/wiki/diamonds/60-60-proportioned-diamond 60/60 refers to table and depth.

They are usually slightly cheaper because not as many angle combinations of a 60/60 come out with ideal light return. But when you find one that does, and you get an idealscope to confirm they are very good buys.

Like these?

HCA = 1.4 EEVE

I'm positive someone here knows that. I just use the HCA. John Pollard would be the best person to ask.

As an aside, the 60/60 make came about as a combination of lighting changes and better yield. There was no grading of cut on consumer reports, so diamonds were often fashioned to look good under showroom lights. As high pressure lighting came into use in the later part of the 1900s retailers found larger tables, lower crowns and narrower pavilion mains made for extremely bright-looking stones when lit correctly. Conveniently for manufacturers, producing such diamonds - as opposed to the "Scientific Cut" adopted by Lazare Kaplan, Tiffany & Company and others some decades prior - also resulted in greater yield from most rough crystals.

60/60 makes are capable of earning EX and/or Ideal at GIA and AGS, although it takes skill since the "bullseye" window of complimentary angles is smaller than makes closer to modern Tolkowsky numbers.

msop04--I will definitely post pics once I have proposed. Should be a few weeks from now.

zz00ter--The diamond I chose had an HCA of 1.4 and the idealscope picture was a strong red except for some lighter spots on the edge where the prongs will be. Also, James Allen reviews 3 diamonds that you send them as a one time courteousy and they said the one I wound up choosing had excellent fire, brilliance and scintilation. The diamond described in the first post of the thread was not the one I chose, I wound up going with the one I posted the link to for Julie. They recommended that one as they felt the faint flour whitened up the color of the J a bit.
From my research it seems 60/60 diamonds are a bit trickier that the average diamond in terms of finding a good one but if you do you can get a really great diamond and maybe a little cheaper than you would a non 60/60. Im a far from an expert and am only speaking from my experience. I am sure there are folks on here that can tell you much more.
