jojobeans91 : Don’t worry about our setting and the stone. Jewelers have been twisting metal for a long time. Shanks were less often twisted when die-striking was the norm, as it was harder to get the metal to really look twisted. But, you will find rope-inspired rings back to the Victorian period. In any case, I think it will look great.
I have to agree that being a prototype for a stone would make me nervous. With that in mind, I would go with Zaya (of your two). Although I’m kinda in love with this moval…
However, I think the ENV oval by JYB Jewels would also look great on your ring! These are cut by hand, so you likely can specify the exact dimension (length/width) you want. The video below is of a chubby oval.
A bunch of Bees have Harro Ovals, you an probably poke around. Harro are cut very similar (facet pattern) to an oval diamond. They have a bit less fire than some of the others, but they look more like a diamond in cut pattern. The below video compares a C&C oval to Harro (1.08 seconds in). With Harro, you can choose crushed ice or not (I generally prefer not, but you have to love it).
Most Bees lately have been preferring near colorless (F/G/H) over colorless as the colorless can be stark and steely to some eyes. A few Bees returned their colorless for near colorless. It depends on the look you like. I prefer warmer diamonds, so I also prefer warmer moissy.
If you are looking to go bigger, they will have to raise the height of the stone over the band to accommodate the greater depth since the cathedral shoulders limit the width at the base and the head is internal to the shoulders. So, once you decide on a brand, and assuming they will be putting the stone in the ring, have them tell you what size stones are possible. If you will just be buying the stone for local setting, have your local jeweler give you guidance on size allowances (in mm) for this setting.
