A friend is looking for a 1.6 - 1.7 ct. MRB Diamond H SI1 trying to keep the price close to $10,000. I looked for a while but ran out of time. If anyone has time to search and help out that would be great!
If it was me, I'd request IS images for the stone recommended from @gm89uk, 1.4 H VVS1, and 1.58 I SI1. But, JA only gives you 3 IS per email. So, this would use up all three. Maybe put the 1.4 on hold and IS for the other 2. Make sure to put your favorite 3 on HOLD asap.
