I love ovals but love elongated cushions even more! :) For some reason I like the look a little better. And I also like having that tiny bit of extra finger coverage too.
But all that said, I still really want an oval w/side pears :)
And I agree with itsoloken re: radiant cuts - those are also at the top of my list :)
Regarding not being able to try on rings - maybe order some CZ cheapies from Amazon or eBay in different shapes... I really love Berricle but they can be a little pricey.
Here's a link to a pretty nice oval: https://www.amazon.com/DYUNQ-Zirconia-Solitaire-Engagement-Sterling/dp/B07S1FTL83/ref=mp_s_a_1_3?dchild=1&keywords=cubic+zirconia+ring+solitaire+oval&qid=1586747076&sr=8-3
