Hi Joe,

First of all, I want to thank you for building this website. This is by far the most informative and statistically backed shopping website I have seen. I also enjoyed reading your research using CV.

I have been shopping for diamonds for a few weeks and want to ask your opinions regarding clarity. My budget is $25k and I am looking at some SI diamond in order to maximize color and weight. (can we have a color clarity curve like ROC curve?? 🙂 )

I found some on JA and would love to have your opinions on it:

  1. 2.07c D SI1 https://www.jamesallen.com/loose-diamonds/round-cut/2.07-carat-d-color-si1-clarity-excellent-cut-sku-10195224
  2. 2.02c D SI1 https://www.jamesallen.com/loose-diamonds/round-cut/2.02-carat-d-color-si1-clarity-excellent-cut-sku-9546115

I also went to a local jeweler and they showed me a 2.30c E SI2 that looked eye clean but with a few obvious inclusions under a microscope (but no bad inclusion in the center of the diamond). I thought the price is competitive at $20,000 but the SI2 is in my head. What is your opinion on SI2 diamond and do they worth buying?

Thank you in advance!
