As mentioned in the topic, I was wondering which search engines do you use when you want to look for lower color diamonds and want to look at the images?
Rare carat goes up to K, James Allen has hardly anything below M (and mostly rounds)...
I've never purchased from here so can't speak to that, but https://www.brilliance.com/loose-diamonds/fancy-color/yellow has a nice inventory to look at, I know it says fancy, but if you go to the colour drop down you can choose from yellow, all the way to w-z! or Diamonds by Lauren.
Yoram at Gemconcepts may be able to custom cut something if you have an idea of what you want, or it could be worth looking at some of the coloured diamond vendors like leibish
