This stone is a no for me, very little red (read bright) and there is clear "mush" in the middle. You can do much better. Can we get your budget and overall requirements please?
Definitely a No...too much leakage under the table.
How big are you trying to get? I suppose as big as your budget allows? I think an H is going to be hard to find because most old cuts are lower in color but can see what we can find.
Edit...I checked Old World Diamond, Jewels by Grace, Love Affair Jewelry, ebay and Diamonds by Lauren
for true old cut cushion and nothing in your color/size/budget.
You might try working with one vendor and seeing what they can find/bring in for you.
Also, other PSers may have some other locations to look. Also, I hear that Adam at Old World Diamond has lots of other stones that he does not have posted on the website so you might contact him and
see what he has.
