Solasfera vs stone from James Allen

[junhox212]

i want to get opinion of people on PS regarding which stone they would pick.

I am after the sparkle of the stone and based on that factor, which stone would you consider better?
The cost of this stones are very identical.

First is:

Second stone is a none certified solasfera stone (doesn't come with AGS or GIA cert), but the gemmex report which shows the light performance was shown to me. Color and clarity is an estimated one from the David S. company.

Since the solasfera is supposed to perform like a super ideal cut stone, would that be the better choice?

They are completely different. The Solasfera has 10 arrows, the JA is a traditional 8 arrow. At this size, I think the extra arrows and facets of the solasfera would be lost - it would be extremely bright, but if you are wanting sparkle I think it would be more pronounced off/on flashes with the fewer, larger flashes of the JA. The Solasfera has more, but smaller, facets and will result in a pinpoint sparkle.

Watch this: (there are lots more Solasfera vs traditional H&A 8 arrow stones on the channel as well)

At this size I would opt for an Ideal cut round brilliant with 8 arrows. I think .4 is too small to appreciate the extra facets of
the Solasfera.
