I was just fooling around with Excel and graphing carats vs price of specifc suitable diamonds (using search by cut quality of excellent). I was able to pull what I thought were good buys by looking for diamonds that fell outside of the normal. I don't know if this would be hard to add to the site and if the graph is really that vaild.

Good Morning. I have three questions:
1.Is there a web site that post Antwerp rough diamond prices?
2. What can I expect to pay for .75 / 1.00 carat rought VS2 H or I/color.?
3. What could I hope to sale a rough weighing .75 to 1.00 carat?
I'm new in the business, I received an opportunity to move to Africa to market (possibly) rough and polish diamonds. Any suggestion and or direction for information would be greatly appreciated

It is doable Larry :wavey:

I was thinking of doing it as a part of advanced section for pricescope. Do you think it would be useful?

Larry,

I did it for my selection but I graphed price vs width in mm -- because I figured that many sellers would miss that but not price vs carat.

In the end, I found diamonds of the quality I wanted ranging from 1157 to $1250 per mm-wide. But I did not select the cheaper ones because there was always somthing not as good about them. It proved futule for e-ring purposes because I did not want to skimp on anything except size. But it would have been good for buying a stone for myself.
