Just got my decagon scope photos

GF chose the decagon in the end. Was deciding between the round 10 and decagon. She picked the decagon immediately which made it easier for me.
We were served by Eugene. I highly recommend him. He brought us to show the SIC and the different white series outside the shop on our request and also under all the different lightings. My gf and I concluded that for some reason, the white series just looks much brighter. We saw a F round 10 that looks even whiter and brighter than a D SIC. Not sure if this makes sense, but its probably due to the light return or facets. In terms of bling and fire, my advice is not to just compare it in the jewellery shop light. When you bring it outdoor, you can see the white series sparkly all over but the SIC have more areas that dont really react.
In terms of what capture your eyes, under all the lightings that we've seen. The decagon and actually the other white series just simply outperforms the SIC. Eugene was kind enough to let my gf compare all 6 diamonds, and she picked the decagon. When she moves the diamonds on their tray, the diamond that captures attention the most is the decagon.
For those who haven't visited JP yet, when you view their white series line, compare them under different lightings and choose what appeals the most to you. Value wise though, I'm very surprised the decagon is not priced much higher than the SIC. Was expecting to pay 40% more, but ended up just a marginal difference for a much higher light performance.
Others bros here got the decagon, do you guys bling up your rings with the decagon melees as well? The ring design is left to me to figure myself and honestly I'm super lost. Any recommendations?
