by cflutist » May 10, 2019 I love Trilogie, but with the current price drop, I could not pass on upgrading my center stone. I replaced the cut to order 2.21 F-SI1 with a 2.18 E-VS1 CBI. The two side CBIs are still .53s F, VS1 and VS2. There is a very slight difference in tint but my phone is having trouble capturing it. Size 4.5 ring. The new AGS report Indoors in natural light and off white ceiling.
