Hello! I'm starting the hunt for a pair of rounds and would love your help looking at whether 2 I found are a good option. I'm aiming for around 4-4.5cttw, D-F color, VS2+, HPHT. Ideally, would like to keep closer to $3k total but can go up to $4k. How do these 2 IGI stones look: LG618401209 and LG576330819? I was only able to find the video for the second stone and was unsure if there was a hint of blue nuance. Also, are the measurements too far off to be a good match? This is my first time looking for a matched pair and appreciate the help! Also open to any suggestions!
